Tooth cosmetic veneering method

Abstract

The invention provides a tooth cosmetic veneering method, which comprises the following steps that: spinels are adopted for porcelain laminate veneering, wherein the veneer thickness can be controlled between 0.5 and 0.8; tooth surfaces are free from being processed, so that painless cosmetology is realized; temporary teeth are free from being worn, so that inconvenience of a person being subject to cosmetology can be reduced; and the tongue side parts of teeth are free from being processed, so that jaw teeth can be effectively protected, and 'foreign body feeling' is free. In the invention, a compound material prepared by a special glass permeation method is adopted, the strength can reach over 400 Mpa after bonding, the durability of the prepared spinel porcelain laminate tooth veneer can reach over 10 years; the prepared spinel porcelain laminate tooth veneer has the optical speciality being the same as that of natural tooth tissues, and has a simulation cosmetic effect; the material has good mechanical and physical properties so as to bear high stress, high acid corrosion resistance, and low heat conduction property so that the tooth body can not be irritated by heating, and no stimulation is caused to teeth pulp when people eat cold and hot food; the material has a self-cleaning capability, so that bacteria are difficult to grow; the X-ray transmission property is good; and the cost is low.

Description

technical field [0001] The invention relates to the field of tooth cosmetic restoration, in particular to a cosmetic method using spinel all-ceramic material as tooth veneer. Background technique [0002] In today's society, with the improvement of living standards, people's pursuit of material has been gradually satisfied, and more and more of them are spiritual pursuits. The spiritual pursuit is most directly reflected in the desire for beauty. Especially in recent years, people's positioning of beauty is not limited to the face and figure, but also pays more attention to the whitening and health of teeth. Having neat, white and beautiful teeth is a One of the top ten health symbols of modern people. It is precisely because of this that tooth beauty is also emerging in the oral industry. [0003] For a long time, various dental problems such as tooth discoloration, especially moderate to severe tetracycline teeth, dental fluorosis, small area cracking, tooth gaps, and mi...

AI Technical Summary

Problems solved by technology

The initial veneer material is directly bonded to the teeth with light-cured resin material, which has poor aesthetics and firmness, and has certain irritation to the gums.

The all-ceramic veneers that are widely used in stomatological hospitals are made of all-ceramic, and are pasted on the surface of the front teeth with high-strength adhesives to obtain a good aesthetic effect, but there are also damage to the teeth, poor firmness, and short service life.
