Dental aesthetic beauty requirements

World Health Organization to develop standards for dental health: teeth cleaning, no cavities, no pain, gum color normal, no bleeding.

It is now only requires dental health, it also requires teeth beautiful, the color from the teeth, the teeth arranged in several respects shape of the teeth, teeth beautiful basic requirements are: white teeth, the teeth arranged in neat rows, the teeth the size of co-ordination, no missing teeth, and defects.

Dental aesthetic beauty is the combination of medicine and the doctor must not only understand oral medicine at the same time, but also know how to aesthetic dental equipment principles, the principles used in cosmetic dental aesthetics on.

Tooth color to meet the aesthetic requirements, to be white, but not pure white, but not the more white the better, can not seem rigid, giving a crystal clear sense, while the other teeth to color, skin color coordination.

Arrangement of teeth not only neat, but the teeth of the center line to center line parallel to the line and face, smile dental floss on the inside parallel to and under the lip, gum is just lip on the inside cover.

Tooth shape to meet the golden ratio, determined by using the golden section ratio of the teeth, not only to increase the balance of smiling mouth, making a smile Adverse impact on dental health habits more natural, more full of vitality and soul, but also to repair the tooth becomes comfortable, good with.

Therefore, when a doctor during the cosmetic teeth, must be based on each person's facial features, lip, skin, teeth shape, gender, age, occupation, etc. for individual well-designed and precision measurement, teeth color, arrangement, and shape must meet the aesthetic requirements.

Four reasons for selection of porcelain teeth

Refers to porcelain dental surgery porcelain dental restoration by dental surgery to achieve deformity correction, about the teeth arranged in neat rows, restore teeth to normal occlusal function. Porcelain teeth straightening teeth biggest advantage is time, pain, and complete dental cosmetic, but also effectively prevent blocking the caries, plaque and other produce.

Choose to do porcelain teeth four reasons:

1. Arrangement of teeth and dental porcelain tooth form if your teeth is too big or too small, not very coordinated appearance, method of orthodontic tooth shape powerless to change, and correction of porcelain teeth in order to solve the same time, a corresponding adjustment of the tooth shape , so that even more coordination.

2. Cost of porcelain teeth cost of orthodontic treatment options in a large space is not very different, but there are a variety of dental porcelain materials, prices vary greatly, each person dental equipment according to their own requirements and economic conditions to select.

3. Arrangement of teeth and tooth color change when you are more serious dental fluorosis or tetracycline, but not neatly arranged in the teeth, orthodontic approach can only change the arrangement of teeth, make your teeth white and tidy, and not Cosmetic Dental Crowns change tooth color. Porcelain can also correct way to solve the arrangement of teeth and tooth color problem.

4. Time is short and orthodontic compared to porcelain teeth correction of the biggest advantages is the time is short, only a week, twice on the line treatment. Orthodontic a long time, adult orthodontics usually takes about two years, during which a referral to a month.

Do you know that lack of a need to make porcelain teeth three

Full name of porcelain teeth are porcelain fused to metal crown, is an ideal prosthesis. It is the first made ​​of metal alloy substrate, and then its surface similar to natural teeth covered with porcelain powder with low melting, high temperature in a vacuum sintering furnace-fused porcelain formed, and thus the strength of metal and porcelain crowns and beautiful .

Porcelain teeth to restore teeth is characterized by morphological features, bending and strong colors, lifelike appearance, smooth surface, wear resistance, no deformation, color stable, successful ceramic restorations should be realistic shape, color and stability. Acid, a permanent prosthesis. With the growing popularity of porcelain teeth, porcelain teeth, people have become dental equipment accustomed to as the preferred method of tooth restoration, but there is often a question is: Why should a tooth missing three inlaid porcelain teeth?

Hospital Dental Center experts say: The patients are usually missing teeth missing tooth, a tooth of the jaw will lose power, so need to lose this tooth to the jaw power of average two teeth next to the bear, which is required the missing teeth on both sides of the teeth after tooth reduced repair to bypass the way, do a group of three teeth based porcelain bridge.

There is also a way to not be so complicated, just do a tooth on it, and that is growing teeth. Implant does not require the normal wear and tear Bad breath is a precursor to serious illness on both sides of the tooth. However, comparison with the implant when the long, costly, not porcelain teeth to the quick. Therefore, patients in the choice of method can be according to their affordability and their need to choose.

Bad breath - how to prevent

Bad breath - how to prevent

First, to develop good health habits, timely and clear the mouth of putrefaction to ensure oral hygiene: pay great attention to oral hygiene, every morning, before going to dental equipment bed and brush our teeth after meals seriously, if necessary, with a toothbrush or a clean towel to gently brushing fur.

Secondly, don't smoking, alcohol; diet is relatively light, avoid eating raw, pungent, smell (such as garlic, onions, leeks, tofu, etc.) and stodgy, greasy (high protein, high fat) food; eating too fast; more water, eat more fruits and vegetables and legumes; lifestyle laws, to feel Root canal treatment is arranged comfortable; take part in physical exercise. Chinese medicine, bad breath is gastrointestinal with "hot", so try to eat to help advocate bad breath in the hot and cold food temperature, amount of heat to eat some hot food consumption.

Treatment should follow the principles of dental caries

Treatment of caries lesions is necessary to terminate the development, protection of health of the pulp, the tooth to restore shape and function, the principle of maintaining the integrity of the dentition.

No or a small amount of tissue defects may still caries treatment. No obvious defects of shallow caries, with drug therapy, re-mineralization treatment, were used at the pit and fissure sealant therapy. Defects of the existing dental caries still, shallow caries, caries in caries and chronic, to fill treatment. Of acute caries and rampant caries in the cavity preparation, the dental equipment drug for temporary filling or sealing, should be re-mineralization treatment, and then the permanent restorative treatment. Rampant caries of the teeth should be full-mouth treatment design and systemic diseases. Susceptible to the caries and rampant caries in the treatment of patients at the same time, giving anti-caries measures, such as clear plaque, control sugar, pit and fissure sealant, remineralization therapy, regular postoperative follow-up observation.

Of shallow and wide occlusal surface defects can be inlays or onlays repair form and function, a large defect of caries can be used to repair or restorative treatment inlays after full crown. The treatment of secondary caries, in principle, should remove the original restorations or restorations, and then light, medium and deep caries treatment principles, if you do not affect the Prevention of oral mucosal disease resistance and retention form type can also be carried out only in the cavity of the local restorative treatment, do not have to remove all backfill or restoration. Pulp and periapical disease of dental caries disease or recurrent caries, endodontic treatment should improve after re-filling or repair.

The orthodontic appliance type

In orthodontics, the appliance use is more common. So in the orthodontic appliance in the end what type? What types of braces do? Experts said that, in general, orthodontic appliance according to their retention in the oral cavity can be divided into removable appliances and fixed appliances into two categories.

Removable appliance structure is simple, during the course of orthodontic wear can pick their own, enabling the maintenance of oral hygiene, but the correction force control is not precise enough. Fixed appliance can be controlled in three dimensions tooth movement, but because dental equipment almost every tooth with orthodontic adhesive on both parts, patients must be carefully brush your teeth to maintain oral health.

In addition, with a wide range of adult orthodontic treatment carried out a biological ceramic brackets and clear plastic brackets, the part of patients to meet the aesthetic requirements. In recent years, developed a new treatment technology lingual What circumstances do root canal treatment appliance technology, allows almost no exposed appliance, but its clinical operation is relatively complex and difficult, more costly.

Above the appliance has its own indications, consumers need to choose the course of orthodontic appliance which need specific professional orthodontic treatment only after a physician determined.

Root canal therapy must know something

Root canal therapy is the treatment of various causes of pulp disease, periapical, preservation of residual crown and root of the preferred method, but also internationally recognized as the most effective treatment. Division I introduce the latest root canal treatment equipment, appliances and materials, to save the past can not keep the teeth, and achieved good results. The high-tech treatment, difficult and dental equipment complicated to operate, treatment for a long time, the price is relatively high. Because the teeth were root canal affected by age, race, genetic, systemic diseases, diseases affecting Chengdu, there are significant individual differences, even if the same individual in different root canal teeth are quite different, which gave the number of root canal treatment more difficult, affect treatment and clinical results after treatment. Root canal treatment process and the following problems The ideal solution for dental cosmetic restoration may occur after treatment, I hope to attract your attention:

1. Drug stimulation of short-term pain, swelling

2. As the root canal Bay, a narrow cause equipment to break or wear through the wall.

3. Born too thin tooth tissue caused by broken teeth

4. Possible allergic drug allergy

5. As the root is too long or bend, and other anatomic variations of the factors beyond the apical foramen instrument, causing local tissue dry and symptoms of numbness

6. The possible removal of carious tissue remaining or residual crown and root

7. As the tooth itself cracked, cracks after root canal treatment may increase or fracture

8. Calcified root canal atresia, the teeth may be removed due to poor treatment

How to choose the color of porcelain teeth

Not a single natural color of human teeth, neck, body, cut side of the color is not uniform, cut-side maximum brightness, saturation neck up.

First, the color of porcelain teeth in the choice of time to try to exclude the external environment affect the color of objects, there are those unclean teeth, first teeth cleaning before repair. Color selection should remove the patient's lip ornaments, choose the color of natural light than under direct sunlight.

The color of the crown of human nature because of race, region and individual differences exist. Most people on the lower jaw teeth color is also inconsistent with the same name, left side of the same name as the teeth of the same color value. Clinically, the side of the front teeth missing, the same name should refer to the contralateral tooth color selection, do not refer to the jaw tooth color selection. On the teeth, central incisors, lateral incisors, canines in order of dental equipment decreasing brightness, saturation values ​​gradually increased. Maxillary canine to the lowest brightness, saturation maximum. Tooth color and age has a close relationship with age, the natural tooth color Zeming gradually reduce the brightness, the color is getting stronger. Therefore, to achieve the best cosmetic results, choose the color, do not over-the pursuit of high brightness, color light hue, brightness and saturation should choose the colors are moderate, and pay attention to the light of the contralateral teeth, the color of adjacent teeth.

Full exchange of views with the doctor, because the different personality traits, when both doctors and patients have different options for color, the more some discussion, in order to obtain the final agreement.

Dental experts suggest that you: choose the color of porcelain teeth, when not more white the better, but to select their most suitable color.
