Dental treatment during pregnancy can reduce the risk of premature fetus

American scientists, a new study shows that pregnancy dental treatment can greatly reduce the risk of preterm delivery and periodontal disease.

According to foreign media reports, U.S. scientists completed a new study shows that, not only safe during pregnancy dental treatment, and can greatly reduce the risk of preterm delivery and periodontal disease.

Dental problems are usually caused by a bacterial infection caused by inflammation of the gum tissue lesions left untreated can cause chronic inflammation lingering. The pregnancy odontopathy is a vexed question. Due to the body hormones suddenly change therefore, pregnant women are more prone to dental equipment. However, the standard tetracycline-based dental therapy is not advocated because the therapy may be dangerous to the fetus. However, substantial evidence that dental itself will increase the risk of preterm delivery.

The new study involved 322 dental tested pregnant women. These women were randomly divided into two groups, one group received an invasive scaling treatment and to accept oral health counseling. Another group of pregnant women receiving oral health counseling. After giving birth, the women, all participants received dental treatment.

The study found that the scaling treatment of pregnant women and Misunderstanding of the tooth whitening pregnant women did not receive treatment premature ratio of 45.6% and 52.4%, respectively. In-depth analysis found those pregnant women, pregnancy successful dental treatment, the risk of preterm delivery was significantly reduced. Scaling group of pregnant women in dental successful treatment of 42 people, and its premature birth rate was only 10.5%, premature birth ratio of 62% in the 111 but not healed dental scaling treatment of pregnant women.

The researchers said the new findings of dental treatment during pregnancy have a positive inspiration. The pregnancy odontopathy the non-drug therapy is safe and reliable, and can reduce the risk of preterm delivery. Therefore, Dr. Jeff Côte suggested, the obstetrician should recommend dental pregnant women going to the dentist in a timely manner, non-drug scaling therapy is a good choice, but successful treatment is essential.

Choice of removable dentures and fixed partial denture

We all know that tooth loss as early as possible to denture repair, dental clinical denture depending on the retention of the dentures in the mouth, can be divided into two kinds of removable dentures and fixed partial denture, then we should choose for removable dentures or fixed partial denture it?

Activities the denture plastic or metal for the denture base denture base attached to the snap ring and dentures, solid bit by card ring hanging on real teeth, patients can pick to wear removable dentures advantages are: a wide range of applications, from the lack of a missing teeth to all teeth can be adopted; less tooth tissue repair ground; could be turned off to clean, easy to maintain hygiene; easy to repair after damage. Removable dentures also some disadvantages, such as volume, first wearing, not suited to the relatively poor chewing function.

Fixed partial denture is co-produced by the metal and nonmetal Underpinning small size. Fixed partial denture retention connected to rely on retainer with real teeth across the real teeth of both ends of the fixed denture set up the same as the pier, the scientific name for a fixed bridge. The narrow range of fixed denture use should be used for a small number of missing teeth and dental equipment I remaining teeth health.

A good fixed dentures, chewing efficiency, comfort, and the co-production of the metal and nonmetal fixed denture beautiful effect is good. The biggest drawback of the fixed partial denture real teeth grinding in addition to the organization, making more difficult.

Choice dentures specific according to the specific circumstances of the patient's mouth and oral and body in good health, the number of missing teeth Prosthodontics less than three, may be appropriate to Six methods to prevent mouth ulcers select a fixed partial denture And if a large number of missing teeth do not want to teeth, then the optional removable denture repair.

Whitening operation

Normally, a healthy white teeth always impressive teeth whitened there are many ways, Whitening is the most common method, cold light whitening procedure what is it?

Whitening operation

   

1. Before the operation start whitening, the dentist first oral Attorney AC patients and whitening, to confirm whether the consumer was in line with the conditions of whitening. After confirmation, the dentist will compare and recorded before whitening teeth color photographic archive. At this time, the medical staff will wear goggles for whitening patients and operating personnel, and a small amount of water and polishing reconcile a simple treatment of the surface of the teeth. After treatment is completed, allow patients to gargle, be sure to dry the surface of the teeth.

2. Whitening dentist will open into the patient's mouth. Determine the patient discomfort; the doctor will be separated from the wet sliver into the lip and the inside of smear Lip oil wear to cover tissue paper. Medical staff will then light-cured resin-coated in the gums, and cover to the subgingival 0.5mm, light curing lamp irradiation for about 3 seconds. After the hydrogen peroxide whitening powder into a paste, a whitening agent is applied in the drying up and down the surface of the teeth of a total of 16 or more will be a good tune, smear about 2-3mm thickness, in this process, adjust illuminometer lamp, lamp with the surface of the teeth was 90 degrees vertically, just contact openings. At this time, you can press the start button, start the first 8 minutes of treatment, after the end of the machine will automatically stop, and then with a strong straw siphoning off a tooth whitening agent, such as the need to use a dry cotton ball to dental equipment wipe the residues in the cold light teeth whitening agent, Do not rinse. Repeat 8 to 10 steps twice, the second and third eight minutes of treatment. If the patient responses tooth sensitivity or pain should stop whitening operation.

      

3. Whitening is complete, the doctor will provide consumers siphoning whitening agent, carefully remove the light-cured resin and sliver water rinse teeth and Dental implant process needs attention between the teeth and remove the opening and goggles. After doing whitening teeth after colorimetric photographic archive.

After orthodontic have hazards?

1. The teeth become loose: under normal circumstances, has a certain degree of Physiological Activity of each tooth in order to be able to buffer the chewing pressure preventing tooth trauma. Do orthodontic treatment, increased tooth mobility, this is a normal reaction. However, this orthodontic side effect can be restored. The teeth you want to move, you need to alveolar bone and periodontal ligament reconstruction, because the teeth are fixed by the periodontal ligament in the alveolar bone in the so that the teeth will become loose. Orthodontics stop moving to the normal position, the teeth can through their own ability to repair. Periodontal ligament reattachment becomes solid, no permanent damage. Clinical tooth mobility too, should be suspended afterburner, afterburner allowed to dental equipment continue after the recovery period.

2. The pulp: Early orthodontic treatment, pulp mild, temporary inflammatory response, manifested as pain or discomfort of the patient within the first few days of the afterburner, but experiments show that this impact of no clinical significance. This is also one of the side effects of orthodontics, but temporary.

3. Root: orthodontics, root surface absorption hyperplasia such reconstruction activities. After treatment, the root with its own ability to repair and return to normal, but the afterburner in the treatment is too large; it will increase the risk of root resorption.

4. Impact on the alveolar bone height: done orthodontic treatment, alveolar bone height will have a small amount of the reduction, which is due to wear the appliance allows the oral hygiene is not easy to Removable partial denture indications maintain, and increase the risk of gingivitis, alveolar bone. Certain effects after treatment is completed, the alveolar bone will not continue to occur absorb if oral health remains good, alveolar bone will gradually return to normal. These are also temporary orthodontic adverse consequences.

Root canal treatment has no effect on health?

The root canal therapy is appropriate disinfection by removing necrotic material within the root canal, root canal filling to remove the negative stimulus of the contents of the root canal apical surrounding tissue to prevent the occurrence of periapical lesions or promote periapical a lesion healing treatments. Pulp necrosis, chronic pulpitis, pulp periodontal syndrome and systemic disease should not be tooth and in need of treatment or temporary retention of teeth require root canal therapy.

We usually refer to the nerve, the competent person's feelings. But refers to the nerve in the oral outpatient treatment, only the pulp nerve, the nerve inside the tooth, the tooth is an empty pipe, there are nerves, blood vessels, arteries, veins, and the role of this nerve is feeling more strong hot and cold and sweet and sour stimuli. Under normal circumstances, this part of the nerve will not pass sensory signals to the brain.

Nerve role nutrition made ​​inside the tooth odontoclasis, teeth slight wear or long natural accumulation into severe abrasion process which will be repaired by dentinal hyperplasia, which is the protection of human mechanism. Partly in order to dental equipment maintain the thickness of the teeth, the dental hard tissue will grow, but the speed is limited, with age, the speed is getting lower and lower. Nerve unplug, and cause teeth nutrient metabolism, no, so the teeth discolored and brittle. Sensory function is generally not affected. When the encounter on our teeth, the teeth, the sensory nerves than Which are in need of dental restorations pulp nerves, but periodontal nerve.

What is the harm of missing teeth is not timely denture?

1. Pronunciation dysfunctional: missing front teeth affect the accuracy of the fat tooth tone, tongue, teeth tone lips and teeth sound this causes the teacher, actor and translator workers inconvenienced.

2. Temporomandibular joint: not timely denture can cause relationship disorders, the disorder but also brought about the emergence of trauma impede mandibular advancement and movement of the side, the side of the most tooth missing form deflective mastication.

3. Cause periodontal tissue lesions: in this area tend to be most people ignore. One or two teeth missing, adjacent teeth can be dumped to the missing tooth gap shift, the shift can be caused by a small gap of the adjacent teeth appear. Dentures which will bring difficulties, but also easy to cause food impaction, lead to periodontal disease, dental caries.

4. Affect facial appearance: lack of teeth affects facial appearance, front teeth missing denture, people naturally will notice the aesthetic problem, but when on, under, after missing more teeth or dental equipment full mouth of teeth missing, the vertical distance of the surface of the lower short, increased facial wrinkles, it seems old, that most people do not experience.

5. Masticatory function will diminish: the main function of the teeth is to chew food front teeth incisors tearing food effect, posterior teeth grinding food, its absence is especially timely denture chewing time without missing greater degree. In addition, the food was chewing also can stimulate peristalsis, food after chewing can facilitate the digestion and How to choose the elderly denture absorption of food mixed with saliva.

How to prevent child tooth decay?

Tooth decay, sometimes some people call cavities, the scientific name dental caries. Its main causes plaque. Adults and children are likely to suffer from tooth decay, but the chance of children suffer from tooth decay than adults, because small children do not brush their teeth, many parents are accustomed to your child to drink a bottle of milk at bedtime or grab a snack. Did not think thereafter should help children to clean their teeth. Children sleep more sleep reduce the secretion of saliva, oral cavity and in a quiescent state, is not conducive to the cleaning of the teeth, which are to increase the chance of suffering from dental caries.

Children should be how to prevent tooth decay, we made ​​the following recommendations:

First. Teach children the correct way of brushing. For children to buy a compact brush heads, bristles and valuables, hair end blunt and child health flexible toothbrush.

Second. Children under 15 years of age should be noted that a reasonable diet. Eat more foods rich in phosphorus, calcium, vitamins, and common foods: milk, soy and soy products, shrimp, seaweed, eggs, cod liver oil and dental equipment other rich in these substances.

Third. Appropriate rough, fiber-rich foods in your diet. Such as: corn, oats.

Fourth. Develop good habits, do morning and evening brushing, especially before going to bed to brush your teeth, maintain oral health.

Fifth. Select some of the fluorine-containing foods, such as: tea, lettuce, cabbage, green onions in the diet. Select toothpaste, fluoride toothpaste.

During childhood, parents should educate their children to develop good habits, in order to reduce the complication rate of dental caries.

Invisible the five advantages of the appliance

Invisible orthodontics modern computer-aided rapid prototyping technology and new materials, the perfect combination of product. Expert’s correction process by computer simulation, and transparent elastic polymer materials for each process to make a correction, so as to achieve the purpose of straightening teeth. Covert treatment, opening laughter I can not see doing orthodontic treatment. Protect the privacy of patients and social image, but also because of its concealment of the correction and fast, more and more oral request by pro-gaze, become adult’s favorable trend of orthodontic technology.

1. Precision: modern science and protection of the perfect effect

Made through the process of three-dimensional computer image technology to simulate tooth movement appliance put on the teeth accurately move to design the right direction, up to fully meet the expected effect of the calculation.

2. Appearance: the orthodontic device is transparent and thin, and completely invisible

Almost completely invisible, among the others unaware orthodontic solve your orthodontic tooth appearance concerns.

3. Comfort: traditional bracket and wire devices

Brackets, wire and other orthodontic devices in the traditional sense, no foreign body sensation and irritation, orthodontic process is comfortable and dental equipment relaxing.

4. Convenient: free to pick with, does not affect the social

Invisible orthodontics, self-pick to wear, does not affect the social, dining, and dating and so on. The doctor in accordance with the plan of correction cycle, mailing each cycle Orthoses and referral less.

5 Clean: the maintenance of oral hygiene is more easily

Invisible orthodontics own removal, oral hygiene easier to maintain, do not have to Need to prepare before orthodontic worry about gingivitis, tooth demineralization, discoloration and other problems.

Caesarean babies susceptible to dental caries

American scientists have recently made ​​a new study shows that, compared with babies born through natural childbirth, the baby was born by Caesarean section are more susceptible to dental caries bacteria infection.

Participate in the study said, when the baby is born, the obstetrician is usually their oral disinfection. Soon after, the baby's mouth would give rise to a lot of bacteria. Most of the bacteria can help babies to improve their immunity and helping to eliminate harmful bacteria.

However, the researchers also found that the mouth of babies born by Caesarean section, the emergence of a relatively early can cause dental caries, Streptococcus mutans. Premature agglomeration of such bacteria to babies born by Caesarean section is susceptible to dental caries in the later days.

Up to four years of follow-up survey on 156 pairs of mother and child, the researchers found, resulting in dental caries, Streptococcus mutans on average 29 months after the natural delivery of the baby's mouth. In the mouth of babies born by Caesarean section, the emergence of these bacteria is usually 17 months later. The results also show that babies born by Caesarean section compared to the natural delivery of baby at birth can come into contact with more dental equipment beneficial bacteria, which will certainly help them to resist the invasion of Streptococcus mutans.

The researchers said that the long gestation and high levels of Streptococcus mutans in the pregnancy the mother's body, with the premature infant oral Streptococcus mutans in the relevant. The researchers also suggested that, by Caesarean section have children and How long does it take to eat after tooth extraction pregnant women themselves suffer from dental caries, children grow teeth as early as possible zone them to the dentist for check-ups.

What are the advantages of dental implant?

Lack of one or a few teeth in fixed prostheses required to grind the edge of the two teeth in the edentulous ridge is small, the pillar as a solid braces, dentures will firmly dentures to do a great base plate as the base care, people do not feel comfortable, foreign body sensation. The implant can be directly implanted in the edentulous ridge implant, fixed dentures, without loss of other teeth, and no foreign body discomfort.

All missing the back of the molar area, in the past can only be fitted dentures. Masticatory function of denture, dentures metal hook easily stuck in the dirt, easy to clean, the metal hook is also easy to reveal the impact of aesthetics. The implant had no shortcomings.

Mouthful of missing teeth, full dentures must make the traditional dentures, fixed weak gum mucosa and soft tissue support alone, not only the denture is easy to loose, poor chewing function, only restore the normal function of three or four. Plus, if your gums uneven force when the alveolar bone will gradually shrink, dentures effect is getting worse. Implant no moving or dental equipment chewing function of poor, and the alveolar bone at the implant site, dental implants to the formation of functional stimulation, slow the absorption of the alveolar bone.

Implant compared with conventional dentures has many outstanding advantages:

1. The masticatory function is much better than the other dentures.

2. Strong retention and stability, like real teeth, the same tie in the patient's mouth.

3. Less grinding or not grinding your own real teeth.

4. Do not need activities necessary teeth denture base and clasp, a large area of ​​the denture base caused by nontaster comfort.

5. The small size, no exposed metal, beautiful and more conducive to The reason of elderly people suffering from periodontitis maintaining good oral hygiene.

6. For some patients with conventional dentures repair difficult or ineffective, oral and dental implant is superior.

Orthodontic take a long time?

Experts point out that mainly depends on the individual teeth, the teeth of the basic conditions of some patients, he may be as long as the correction above or below a row of teeth on the line, and time will be shortened relatively. For some teeth, the situation is more complex patients, the need for multi-step orthodontic procedures; such orthodontics time will be longer than others and may need to wear for life dental retainer.

Some people's teeth to move up will be relatively fast, the time of straightening teeth may shorten. Usually about will be completed in about 1-2 years time. Some people's teeth grow strong; move up will be more difficult, the orthodontics time will be longer, it normally takes about 2 years.

Crowded teeth corrected to children and adults are not the same. If the children to be corrected, then, relatively speaking will be relatively short. Because the teeth of children currently in a growth phase, especially 13, 14-year-old children, at this time is the golden period of correction. The time of the child during orthodontic usually between one to one and a half. Adults need correction, and dental equipment then the relative will be a long time, at the time of the adults over the age of 18 orthodontic longer.

During orthodontic period, usually every other month is necessary to the hospital for an adjustment of the teeth, this process is also very important. Oral doctors with the patient's tooth morphology change, develop a program suitable for each patient.

Some friends worried that the correction for too long will not want to orthodontics, in fact, having too much to pursue this issue, because the time will be able to Root canal therapy needs to pay attention squeeze out.

What needs to be done to root canal treatment?

Necrotic pulp and periapical diseases of teeth needed root canal treatment. Root canal therapy is appropriate disinfection by removing necrotic material within the root canal, root canal filling to remove the adverse stimulation of the root canal contents on the periapical tissue, prevent the occurrence of periapical lesions or promote periapical lesion healing as a treatment method.

Pulp necrosis and chronic pulpitis, pulp and periodontal syndrome and systemic disease not suitable extraction and in need of treatment or suspension of retained teeth are indications of root canal therapy. The following in root canal treatment:

1. Bite when spontaneous pain or tenderness.

2. Sensitive to hot and cold food and the discomfort continued.

3. Severe caries or trauma leads to abscess of the alveolar bone.

There are two ways in the implementation of the root canal therapy.

Double or multiple method: first cavity preparation of opening the chamber to flush the canal, and removal of necrosis, gangrene of the pulp, expand the root canal, and dental equipment again rinse clean root canal, enclosed disinfection drugs after sucking about 2 to 7 days; If there is no referral The obvious reaction, namely removal of the seal material, filling the root canal, if there are significant reaction, can be re-enclosed disinfection drugs, the next root canal filling.

The first method: the system open pulp, rinse, expands the root canal, root canal filling immediately, once completed.

The process of root canal therapy doctor root decomposition products, closely filling the root canal, isolated from the bacteria into the root canal re-infection, to prevent the periapical lesions or Do you really know how to choose good porcelain teeth promote the healing of periapical disease. Root canal treatment to ensure cure teeth, to try to save teeth in masticatory function.

How the effect of all-ceramic dental?

The all-ceramic tooth is only in recent years carried out a high-tech dental. In the treatment of the root a crown, the crown is a layer of porcelain transparent support skeleton, and then baked on the outer crown surface layer and the natural tooth color similar to the ceramic powder, and finally bonded to the teeth. All porcelain teeth in the oral cavity indications can be severe tetracycline stained teeth, dental fluorosis, abnormal teeth, discolored teeth and various all-ceramic repair is a good quality of a dentition defect fix.

First. The all-ceramic tooth color closer to real teeth.

The most prominent feature of all-ceramic dental realistic appearance. All porcelain teeth using advanced ceramic material does not contain any metal, with air, water or other electrolyte contact, rapidly produce micro-oxide film, to avoid bacterial regeneration. Inside and outside of all-ceramic dental porcelain body, good permeability, the reflection of light closer to natural teeth. Its color, brightness, extent than the ordinary porcelain teeth closer to the real teeth, and color seems to be particularly active. The all-ceramic dental restoration technology can also be selected according to each tooth patients own conditions and needs, to achieve the dental equipment best results, personalized teeth.

Second. Biocompatibility of all-ceramic dental better.

Many people, especially women are allergic to the metal in the metal ceramic crowns, so many patients out of the considerations in this respect, more willing to choose the all-ceramic dental restoration. The adaptability of the all-ceramic dental restorations in the oral cavity than any other metal porcelain teeth, do not have to worry about metal allergies and other issues. Metal allergy can cause gum swelling, bleeding and other phenomena, full porcelain is basically found no sensitive cases. And a good all-ceramic to prevent gingival discoloration, base metal in the oral cavity formed by oxidation of the gray oxide, bulk deposition to the gingival margin, causing the gums to be grayed out and affect appearance. All-ceramic restorations completely solve this problem.

What are the advantages of dental implant?

Much edentulous patients of all ages dental implant, dental implant is a new teeth appear following the traditional removable and fixed teeth, compared with traditional dental methods have many advantages, below, to listen to introduction of the Dental Hospital experts:

1. The masticatory function significantly better than many traditional dentures.

2. Retention and stability, has a strong like real teeth, like rooted in the patient's mouth.

3. From time to grind your own real teeth does not lead to the adjacent teeth caries periodontal disease.

4. Do not need dentures must denture base and clasp a large area plastic denture base caused by taste dull and comfort.

5. Small size, no exposed metal, beautiful, conducive to maintaining good oral hygiene.

6. The dental implant surgery is a smaller alveolar surgery, similar to pulling teeth, local anesthesia, and trauma, after surgery you can eat almost no pain. General implant surgery only requires tens of minutes to hours that can be completed. As the use of sex excellent biological material is compatible with the human body, dental implants on the human body does not produce any adverse side effects. Osseointegration of implant failure can be improved method of replantation after removing or changed into ordinary dentures.

7. Dental Implant is the prevention of bone to dental equipment attract and keep the alveolar bone. After 40 years of development, the dental implant has developed into a mature, reliable, high success rates, new technology, is widely accepted in Western countries.

8. The use of longer statistically can use only 40 percent four years after the partial denture. 10 years 35%, 44% of the abutment injury loss in 10 years, fixed dentures life of 10-15 years, dental implants without caries, endodontic and Porcelain dental restoration pros and cons of identification periapical disease risk, peri below periodontitis long-term effect is higher than the fixed partial dentures, far higher than the removable partial denture.

Why not do the low cost of porcelain teeth?

Dental restorations, many people have heard of porcelain teeth, some time ago ignited the beauty crown in real terms is porcelain teeth, porcelain teeth, as is currently the most common type of dental restorations, whether from dental restorations and cosmetic results porcelain teeth are pretty good, and the price of porcelain teeth is much cheaper than dental implant, but do porcelain teeth must not blindly seek cheap.

Many people think that the high price of water also like to choose the cheapest, these people might say, just not the same price level is nothing more than materials used, there are other What is the difference?

The name of cheap signs of oral body porcelain teeth, gingival retraction agents modulo without retraction cord, silicone modulo the expense of the porcelain tooth cervical margin micro leakage method to reduce costs and more hospital this are looking for in the processing of a number of irregular factory processing, they will use some inferior material to produce the maximum to dental equipment reduce costs, the most crucial point, not the regular small clinic irresponsible, basically there is no after-sales service a problem to find people.

Oral health is how much money can not buy regular hospitals are clearly marked, transparent fees, charges, although not really cost-effective, in general, low-cost porcelain teeth the following hazards:

1. Porcelain teeth generally this time of life is very short.

2. The use of inferior materials, poor quality of the porcelain teeth, it is easy to go wrong.

3. If you are using materials harmful substances, it will directly affect people's lives and health.

What is the crowding correction method?

Crowding will affect the teeth clean, weakening the role of self-cleaning of the teeth, and life on the dentition crowded concern for crowding the main correction methods to expand the dental arch, brackets invisible appliance treatment, the teeth orthodontics, America crown four, the following is the introduction of these four treatments.

Crowding correction method: the method of expanding the dental arch.

1. The bow of the external maxillary lip molar applicable to the distal end of the second molar before the eruption, the first permanent molars forward cases. The teeth on each side after the shift to the distal 3-4mm.

2. Removable appliance to carry out the split reed placed on the arch appliance, finished arch expansion screw, when the arch is to expand the crowded teeth Office needs plus attached spring, such as reed to row teeth. For moderate and severe crowding treatment, generally use the subtrahend and appliance therapy.

Crowding correction: bracket invisible appliance treatment

Through a dedicated, advanced computer software to simulate the correction process, and transparent import elasticity of medical polymer materials for each process produced an appliance; the entire treatment process is, for this series appliance, a handsome, almost entirely invisible effect. And easy to use, free to dental equipment pick wear, and a decrease in the number of times that require referral

Crowding correction: Orthodontics

1. Mild crowding in the crowded dentition mild correction of clinical reverse the dislocation often show the upper and lower incisors or canines mild lip to the dislocation, usually braces orthodontic correction.

2. Crowded dentition with moderate and severe correction of moderate and severe crowding commonly used the subtrahend tooth with orthodontic treatment.

Crowding correction method: cosmetic dental crown:

It breaks through all the disadvantages of the traditional porcelain teeth, misplaced teeth, deformed teeth of the clinical crown part to impose professional and Yellow teeth whitening technical correction of the last cosmetic dental crown. Cosmetic dental crown treatment time is short, and generally the whole process about a week, can change the size, shape, color, and malalignment of the teeth.

After tooth extraction dentures can cause gum disease

Some oral tooth loss, in particular, does not attach importance to the absence of l-2 teeth. They believe that the side of the teeth, you can use the other side; the back teeth did not make do with the front teeth. Doctor’s advice, after tooth extraction, a long time without teeth, will give the entire oral and maxillofacial a wide range of impact.

Missing teeth parts caused chewing dysfunction

Because of a missing tooth is often caused by disuse of the side of the teeth, the results caused by missing teeth and side teeth because of disuse and periodontal disease and increased incidence of dental caries, while the elongation of the jaw teeth without contact to dental equipment cause food impaction, while the other side of the tooth because of the burden of excessive wear could easily lead to food impaction, periodontal disease, dental caries.

Long-term missing teeth and adjacent teeth easily tilt

Because missing teeth and tooth gap easily formed, and subsequent food impaction, periodontal disease and cause premature contact or interfere with the elongation of the jaw teeth, leading to bite the co-disorders.

The missing tooth can cause the lesions of temporomandibular

Missing teeth and severe cases, prone to the problem of limited mouth opening, joint pain, joint snapping. Of course, the temporomandibular joint disorder etiology is complex and What issues should pay attention to pulling wisdom teeth difficult long-term temporomandibular joint disorders in clinical cure. Missing teeth is indeed a very important one of the causes.

In addition, the lacks of front teeth affect the appearance and pronunciation. In view of the above factors, the patients after the proposed extraction must be on time to the hospital bordered dentures.

Oral treatment of pregnant women Note

1. Drugs: treatment of diseases of the teeth, mostly under local anesthetic to the patient relaxes. But pregnant women should avoid the depth of anesthesia. Other drugs, such as: pain relievers, tranquilizers, antibiotics dental most of them are safe, but it should be used with care under the direction of the physician.

2. X-ray irradiation: any dental radiographic dose is very small, and away from the lower abdomen, all within a safe range, but pregnant women is still best to avoid. However, if pregnant women due to the emergency needs to be exposed X-ray, you are required to dental equipment wear protective lead clothing, and especially over the stay abdomen. Pregnant dentists and assistants also should pay attention to their own protective measures.

What are the indications do dental implant?

From the aesthetic effect and functional restoration of missing teeth, dental implant restoration is the preferred way. Theoretically, the implant restoration is applicable to all types of teeth missing. Dental implant indications are detailed as follows:

1. The general condition of good physical and mental health, bone and tooth development has been finalized by the adults to do the dental implant.

2. Jaw alveolar surgery and trauma at least six months or more after at least 3 months after tooth extraction, bone defect has been restored, plant gums, bone morphology and good quality.

3. Oral soft tissue without significant inflammation, lesions.

4. Missing one tooth, several teeth, and all patients with missing teeth.

5 Professional physicians, oral examination, to shoot a panoramic X-rays and do routine blood examination point of the dental implant indications, contraindications, if any bleeding disorders, hypertension, heart disease, diabetes and dental equipment other systemic diseases. Disease in patients with stable before they can receive the dental implant.

6. Wear traditional dentures solid potentiometer, non-functional, and mucous membranes can not tolerate.

7. Alveolar absorption serious jaw full mouth of missing teeth, wearing traditional The life of porcelain teeth complete denture difficulties, is not good, wear is not strong persons.

Orthodontics failure symptoms

Orthodontics failure symptoms

A lot of people on the understanding of orthodontics are quite narrow, leading to many options some incorrect correction, ultimately brought new suffering, and add a burden to their spiritual and material.

One. The harm caused by improper design

1. Pulled out the wrong tooth, resulting in malocclusion deformity. Recommended reading: adult orthodontics against?

2. Correction not sure, some teeth aligned, but do not have the correct occlusion.

3. Only partial considering the uniformity of the teeth without considering dentofacial functional recovery, resulting in temporomandibular joint dysfunction, affecting the normal chewing, appear to eat pain and dental equipment other symptoms.

Two. Hazards caused by improper use of force in the orthodontic process

Orthodontic process, excessive force, and may appear swollen gums, root resorption, etc., and some will lead to loose teeth or even fall off.

Three. The braces inappropriate choice of the harm caused by

1. The instability of the brackets come off easily corrected time will be How do the front teeth to open and close extended.

2. The depth to stimulate the oral mucosa, as well as increase of oral ulcers and gingival hyperplasia.

3. Corrective forces can not reach equilibrium, make orthodontics failed.

Orthodontics failure symptoms

A lot of people on the understanding of orthodontics are quite narrow, leading to many options some incorrect correction, ultimately brought new suffering, and add a burden to their spiritual and material.

One. The harm caused by improper design

1. Pulled out the wrong tooth, resulting in malocclusion deformity. Recommended reading: adult orthodontics against?

2. Correction not sure, some teeth aligned, but do not have the correct occlusion.

3. Only partial considering the uniformity of the teeth without considering dentofacial functional recovery, resulting in temporomandibular joint dysfunction, affecting the normal chewing, appear to eat pain and dental equipment other symptoms.

Two. Hazards caused by improper use of force in the orthodontic process

Orthodontic process, excessive force, and How do the front teeth to open and close may appear swollen gums, root resorption, etc., and some will lead to loose teeth or even fall off.

Three. The braces inappropriate choice of the harm caused by

1. The instability of the brackets come off easily corrected time will be extended.

2. The depth to stimulate the oral mucosa, as well as increase of oral ulcers and gingival hyperplasia.

3. Corrective forces can not reach equilibrium, make orthodontics failed.

Anterior open bite together how correction is better?

Anterior teeth opening and closing the upper and lower teeth when biting, no occlusal contact in the vertical direction. The experts said that great harm to the opening and closing the front teeth, anterior opening and closing of the serious impact on the front teeth of the cutting function, and affect swallowing function, and voice capabilities.

Anterior open bite together how correction is better? The molar neutral relationship, far in the relationship or near relations. The front teeth opening and dental equipment closing of the patient, you can use orthodontics treatment, of course, the most appropriate treatment should be targeted at the underage crowd, not only can achieve a good therapeutic effect, the time spent is relatively shorter.

Beauty crown treatment

Dental Hospital of experts, cosmetic crown treatment of orthodontics is a very safe method, using this method will not cause damage to the teeth, teeth postoperative natural beauty, and real teeth, there is no difference between the effect of a lifetime to keep the not let others know that you have done the cosmetic dental surgery.

What are the types of common porcelain teeth?

The teeth are beautiful enough, brilliant smile enough, confident enough? These troubled people before a big problem, and now no longer exist. The all-ceramic dental help you all get. That all porcelain teeth, what?

All-ceramic dental material effect of a better one. Is only in recent years carried out a high-tech dental method. In the treatment of the root a crown, the crown is a layer of porcelain transparent support skeleton, and then baked on the outer crown surface layer and the natural tooth color similar to the ceramic powder, and finally bonded to the teeth.

What kind of common porcelain teeth? Hainan 187 digital hospital oral Center experts pointed out that the now commonly used in clinical all-ceramic dental general types:

1. High strength and toughness of alumina ceramic teeth has been proven successfully used the shuttle's heat shield, the Porsche brake disc and man-made transmission with the much larger than the other known non-metallic ceramic, it's tough.

2. Casting all porcelain teeth

After casting all porcelain teeth to make the appropriate tooth model with wax, and then proceed to a high temperature wax steps, and finally will make good porcelain block melt through pressure cast into the circle, all-ceramic dental finished product is complete. The cast of all-ceramic teeth are beautiful, good translucency, refraction similar to dental equipment the enamel, dental cosmetic results closer to the natural teeth.

3. Zirconia all-ceramic dental

Zirconia all-ceramic tooth is a full-porcelain teeth produced by the slip casting method, is coated zirconia refractory tooth model slip in the high temperature so that the molding. In the 1970s, the German name VITA invented the technology of In-Ceram all-ceramic dental strength has been greatly improved, and quickly applied to How corrections buck teeth the clinical, all-ceramic dental realistic aesthetic dentists shocked, even the dentist difficult to distinguish which one is dentures.

How to repair dental implant tooth loss?

With dental implants are becoming increasingly popular in modern society, more people learned of the dental implant is a new method to repair missing teeth, but when it comes to dental implant technology and remediation, the relevant knowledge of dental implant not enough to understand.

Dental implant, also known as implant denture, known as human vice teeth. It is divided into implanted in the human jaw implants and commitment to the crown part of the chewing role. Doctors according to the situation of patients with alveolar bone, the appropriate choice of dental implants implanted in the jaw, and dental equipment then installed in its exposed mouth planting pile crowns, natural tooth form and function.

Repair missing teeth, dental implants are the natural first choice, the effect of dental implant naturally, without compromising the adjacent teeth; there is no sensation, no damage to restore chewing texture, and many other advantages, a lot of missing teeth in droves. After years of development, dental implants have become one of a mature oral rehabilitation treatment.

The so-called kinds of teeth, as people type of work in the medical implant, called implant denture. Will be buried in the alveolar bone implant, there is no rejection, and How fast to prevent tooth decay pain then to the implant as the foundation on which to repair teeth. This may dispense with the general set dental care, to make a snap ring or plastic prop, and set fixed teeth to cut the troubles of their own good teeth.

What kinds of porcelain teeth?

Porcelain teeth is a state-of-the-art dental, It can fix defective teeth, cosmetic teeth, by the people of all ages and types of porcelain teeth What is included?

1. Ni-Cr alloy porcelain teeth. Composed of nickel, chromium, beryllium, manganese and other metals. Features: high strength, cheap, very few patients have allergies.

2. Platinum-palladium alloy porcelain teeth. Platinum, palladium, silver and other metal components. Features: corrosion resistance, good biocompatibility, color and more realistic, stable performance, not collapse porcelain.

3. Titanium porcelain teeth. Titanium, nickel, chromium and molybdenum and other metal components. Features: high metal intensity, and porcelain combined with strong, good color.

4. Gold-platinum alloy porcelain teeth. There are 90% gold, 9.5% platinum, palladium and other metal components. The combination of features: metal and porcelain is more solid, edge seal, the color is more beautiful, but the price is higher.

5. Cast porcelain teeth. Within the crown of lithium-based ceramics, the strength can be as high as 420mpa. The process is prefabricated casting pressure ceramic casting pressure for the restoration and then porcelain or color in more than a thousand degree heat. Characteristics: superior in appearance to metal porcelain teeth, the color closest to the real teeth, the crown did not stimulate the gums, the reflection of light closer to dental equipment natural teeth.

6. Gold deposition porcelain teeth: Material: gold content of 99.9%, a special process, the accuracy of the ordinary process can not be achieved. Features: better protect the tooth base pile crown, bridge fit excellent, good biocompatibility, vivid color porcelain.

7. All-ceramic porcelain teeth. As the kernel with special, very high levels of alumina or zirconia ceramic materials, porcelain and then do the surface finishes, or Why porcelain dental treatment needs of the teeth the dyeing process. Ceramic restoration PFM necessary metal crown. Features: translucency of the crown better, more beautiful, but the strength is somewhat less, used for the cosmetic restoration of anterior teeth.

What types of porcelain teeth?

There are many types of porcelain teeth, many people will choose porcelain teeth to repair teeth, but the face of a lot of porcelain teeth in the market, and it is foggy! In fact, the types of porcelain teeth and prices are closely related; species will inevitably affect the price. Different materials, different types. Below the mouth of the experts to explain the types of porcelain teeth:

Porcelain teeth perfect teeth to provide a fantastic treatment: crystal white, uniform shape and does not affect chewing function. This tooth savior of dental defects, missing dentition, teeth, tetracycline, dental fluorosis, deformed teeth and residual roots can be repaired. Recommended reading: the characteristics of each of the types of non-precious metal porcelain teeth

Types of porcelain teeth, porcelain tooth material selection, mainly to dental equipment see the production of materials of porcelain teeth, basically non-non-precious metals, precious metals and ceramic three materials:

Non-precious materials have titanium, cobalt chromium alloy, nickel-chromium alloy materials, improved materials, does not appear the phenomenon of nickel-chromium alloy are allergic to the gums and other organizations, and the biological capacity of these materials been greatly improved, the binding force is also strong, in color, these non-precious metal colors with the color of natural teeth is Orthodontics is the most suitable time similar for those patients with less demanding on the beautiful, the type of porcelain dental material is a  better choice.

When is the best age for orthodontics?

Orthodontics for dental anomalies, the most effective method, but orthodontics is the best age. If you missed the orthodontic best age during the orthodontics are not so easy, then how big the best age for orthodontic? Following oral hospital authoritative experts tell us about.

The first stage is the primary teeth of young children (3-6 years), there are a lot of growth, development potential, and should not be put to immediate use in the primary teeth of the correction means. Some deciduous teeth malocclusion or early correction. Such as anti-together, including the anterior and posterior teeth reverse bite; sucking means, tongue and other bad habits caused by occlusal deformity, early correction is extremely beneficial to the teeth, together, the surface normal birth.

The second stage is the teeth of (6-12), and the exchange of permanent teeth eruption period, deciduous shedding. In the teeth of, or dental equipment should seize the opportunity to be correcting. However, the teeth of the appliance must be very cautious in all appliance design, without prejudice to the facial growth.

The third stage is the permanent dentition (12-16 years), this period of correction suitable period of most people. General orthodontic treatment can be actively carried out. Correction after the occlusal deformities of various phenomena will be varying degrees of The role of deciduous permanent tooth germ significant improvement. Either method of correction of the teeth aligned should have a retention period, which normally takes 6-12 months.

Secret for your dental fillings process details

Many people think that depends on the dentist to feel a headache, feel the fillings is a very scary thing, the fillings process you, so you clearly fillings details.

Experts for you to resolve the whole process of the fillings. The experts tell us, the process of filling in four steps: cavity preparation, sterilization, filling, polishing or polishing.

1. of the cavity: the cavity preparation is the dental drill stage. The doctor needs to do the process of cavity preparation: (1). In addition to the net diseased tissue, otherwise it will cause secondary caries. (2). Protect the pulp and healthy teeth. (3). To establish a good solid shape and resistance form, so as not to backfill broken off and not close together and cause secondary caries. The cavity preparation is the first step in the process of filling.

2. The cavity preparation is completed, the vast majority of infections in the teeth has been cleared, the disinfection process in order to better eliminate the remaining infection, the need for further cavity disinfection. Disinfection cavity drug should have a strong bactericidal damage the efficacy of pain relief and comfort to the pulp, no discoloration of the teeth, does not affect the performance of the filling material and other properties. Disinfection is dental equipment the process of filling in the second step, this process is particularly important, a direct impact on dental patients when will the pain.

3. Filling: The filling is a filling material to fill the nest inside the cave, according to prepared. The filling process is very important, non-metallic materials and metallic materials commonly used filling material, the filling is the process of filling in the third step, this process requires a doctor a good grasp of what materials. The material used in different situations is not the same.

4. Polished or polished: the surfaces of the teeth need to be smooth, and fill in the solidification Shique not with everyone. Polishing or polishing purposes is Crossbite orthodontic treatment of anterior teeth and root the filler surface subtle uneven polished. Polishing or polishing is the process of filling in the fourth step, the final step.

Complement the dental process, although only just four steps, but the materials used, the doctor's professional and cautious fillings of your success affect greatly, so the fillings need to select the regular hospital at the same time, if your fillings, there is obvious discomfort, the need to timely inform the attending physician.

The gingival margin of porcelain dental restoration black line

My teeth are decayed tooth made of porcelain teeth, there are already six years, and now the gingival margin black line, should be caused by the kind of metal dentures. Filmed a piece to the hospital, apical shadow, a doctor said porcelain crowns, will not bring disaster to the other teeth; another doctor says to do root canal treatment, but the gums will do a root canal treatment while black. In the end who said it was real? I intend to replace the all-ceramic dentures, the dentist at the clinic said the apical shadow on the need to do root canal treatment, but I'm afraid the gums will turn black is because black I want to change the, for that matter, clinics the dentist also positive answer in the end I will or dental equipment will not. 

Want kind of help:

1. Root canal treatment really makes gums turn black? Is not necessarily to do? In front of the hospital the doctor said to put the dentures would not bring disaster to the other teeth, whether it is true, if true, put on all-ceramic tooth can not have to do root canal treatment?

2. All-ceramic tooth is replaced; the original black gum line will disappear?

Satisfied with the answer

1. Root canal treatment will not cause gum discoloration. Gingival discoloration is generally a long time caused by a metal oxide deposition is common metal Gingival color porcelain former the use of dental porcelain restoration time. Apical shadow is usually apical inflammation, this proposed treatment. Later to exclude the hidden pain, all-ceramic dental restoration.

2. Replaced with full porcelain teeth, gums black line, not everyone will return. Depend on the constitution. In short: A long-term effect of root canal therapy is recommended to do. For aesthetic all-ceramic tooth needs to be replaced. Specifically how to see your own choice.

Typical cases

Male, 30-year-old crown fracture 10 years ago had the line of disposable plastic crown after the fold due to the labial root, remove the original post crown, and pull the piece of labial teeth. Check: labial root oblique fold subgingival 4 mm, no loosening of teeth, front teeth deep overbite. X-rays showed normal root length and periodontal, has been in the RCT. Recommendation: Porcelain crown after. Disposal: Gingivectomy to the defect surface is revealed, the practice of root canal abutment preparation, casting crown pile in the basement, porcelain, try them, and zinc Ting cements. Repair the abutment crown border and the opposite side of the same name as teeth and adjacent teeth, the patient Heart, labial tooth structure is relatively thin, due to lower occlusal and Zhu Huanzhe Do not bite hard food. Before the repair is completed, to be cover up with gutta labial defect.

Discuss

Gingival defect or shrink the patients, because of the clinical crown length, affect the appearance. Thus, repair, pay attention to the crown and the crowns of adjacent coordination, the use of gingival color porcelain can deal with this problem. Clinical crown lengths, arm length, thus, the abutment preparation to eliminate the thin wall, increasing the length of the dowel pins, adjust the bite.

Gingival defect in patients with periodontal more dental equipment or less disorder, very detrimental to the repair. Thus, before the repair to completely cure periodontal disease, and to teach patients to maintain oral hygiene approach, so that the abutment teeth gums well-being, color co-ordination with the adjacent teeth. Red, swollen gums must be clear and the boundaries of gingival porcelain, not real ones. Gingival porcelain with patient’s gingival edge and tooth structure to seal, lubrication, natural transition, can not constitute an overhang, to stimulate the gums.

Gingival porcelain is slightly prominent in the crown porcelain manufacturing to pay attention to the smooth continuation between the two not rugged indefinite, or Early childhood prone to dental caries the existence of sharp edges burrs, incurring the premises staining or food retention.

The composition and type of fixed partial denture

One. The composition of the fixed partial dentures: retainers, poetics, and connectors, composed of three parts

1. Retainer: the production in the abutments and cements the crown post crown, partial crown or inlay, the connection body connected with the bridge, fixed bridge abutment to form a functional whole, and fixed bridge to obtain retention.

2. Pontic: that is, the artificial tooth is part of the fixed bridge to restore form and function of the missing teeth.

3. Connector: is the part between the fixed bridge retainers. : Fixed connection body, the activities connected body

Two. The type of fixed partial dentures

1. According to the relationship between the bridge and the alveolar ridge can be divided into contact, non-contact

2. According to different materials can be divided into the metal bridge, non-metallic bridge, metal - non-metallic bridge

3. Depending on the fixed bridge structure can be divided into fixed bridge, cantilever fixed bridge, fixed bridge, composite fixed bridge

Fixed bridge features:

(1). Retainer and bridge the connection between the form of a fixed connection, abutments, retainers, bridge connected into a fixed overall composition of the new chewing units; the physiological movement of a single abutment into the overall physiological movement

(2). Abutment teeth can withstand larger occlusal force, and both ends of the abutments are sharing the occlusal force more uniform

(3). Extensive clinical application

Semi-fixed bridge features:

(1). the end of the retainer for a fixed connection, the other end of the active connection. Active connection to the body in the bridge section made of the dental equipment bolt body, the chimeric the abutments retainer bolt Road

(2). Uneven both ends of the abutment the stress

(3). Cases for the inclination of the abutments, it is difficult to achieve common place Road

Single-ended fixed bridge features:

(1). only one end of the retainer contact with the fixed connection, the bridge contact with the other side of the adjacent teeth or adjacent teeth to Fixed partial denture maxillary full dentition form a completely free end

(2). Force, resulting in leverage, easy to cause damage of periodontal tissue trauma or retainer loose

(3). Missing teeth and gaps, to withstand the occlusal much abutments have enough supportive and retentive force

Composite fixed bridge features:

(1). A combination of two kinds or more than two kinds of simple fixed bridge

(2). Intervals, including at least two teeth and at least four dental units

(3). Support and retention and the location and shape of the abutment and hard to find a common place Road

Three. The special structure of the fixed bridge: fixed bridge implant; fixed - removable joint bridge; bonded fixed bridge.

Fixed partial denture should be qualified

The bridge is an important part of the fixed partial denture missing tooth morphology and function. The designs of the bridge directly affect the repair effects and oral health. The bridge should have the following conditions:

1. Able to restore form and function of the missing teeth.

2. The role of self-cleaning, to meet the oral health requirements.

3. Have sufficient mechanical strength, chemical stability and good Histocompatibility.

4. Beautiful and comfortable.

In the bridge design should consider the following questions:

1. The occlusal surface of the bridge: First occlusal morphology better, sharp clear pit and fissure ridge, is conducive to chew. Second, the size of the occlusal surface than dental equipment normal teeth small, in order to reduce the occlusal force.

2. Gingival surface of the bridge: one to keep clean; second, good-looking; the Mihashi abutment height smooth to prevent inflammation.

3. The axial plane of the bridge: In addition to the resume form, to meet the aesthetic requirements, but also pay attention to food row overflow, to restore the correct shape protrusion.

4. Bridge's strength: the strength of the bridge refers to the bending strength of the bridge. To occur when the bridge to withstand the occlusal deflection, abutments will produce the response of the flexor moment, when the stress is Dental orthodontic tooth more than 60% greater than the retention force of the retainer when the flexor moment, make the retention of cortical from the abutment.
