How to choose porcelain teeth scientifically is the most important concern of every patient who needs porcelain teeth. In order to enable patients to correctly select the most suitable for their porcelain teeth, the types of porcelain teeth and the differences are briefly introduced for your reference.
At present, porcelain teeth are mainly divided into two categories: metal porcelain teeth and all-porcelain porcelain teeth.
Metal porcelain teeth are also divided into non-precious metal porcelain teeth, semi-precious metal porcelain teeth, precious metal porcelain teeth and titanium and titanium alloy porcelain teeth. All-porcelain teeth are also divided into ceramic teeth, cast porcelain teeth, aluminum dioxide porcelain teeth, zirconium dioxide porcelain teeth.
A, non-precious metal porcelain teeth
Nickel-chromium alloy porcelain teeth: the metal for the porcelain substrate, biocompatibility is poor, a part of people will occur allergies, nickel, beryllium, the slow release of elements, will cause gum discoloration, usually rarely used in developed countries. The advantage is the low price. So I do not recommend patients to do this kind of porcelain teeth .
Cobalt-chromium metal porcelain teeth: physical properties can be, because it does not contain nickel, biocompatibility greatly improved, the probability of causing gum discoloration is also reduced to the German BEGO company cobalt-chromium alloy is the most ideal for patients who do not require very high restoration effect or can.
Titanium and titanium alloy porcelain teeth: titanium has good biocompatibility, non-toxic to humans, while having good corrosion resistance, is currently a better development of metal materials, but due to the high difficulty of the production process, the development of clinical applications to be further studied.
Second, semi-precious metal porcelain teeth
Silver palladium alloy porcelain teeth: silver palladium alloy for porcelain substrate, due to the completion of the porcelain dental substrate is white, so the market is also known as white gold porcelain. But now due to the stability of silver in the oral cavity to be further studied, so the silver palladium alloy porcelain in the reduction.
Gold palladium alloy porcelain teeth: palladium is a very good biocompatible precious metal, gold and palladium together, the precious metal content has reached about 80%, with a fairly high biocompatibility. Porcelain teeth cervical edge gums rarely occur vegetation through black, gum black line, etc., generally will not cause gum discoloration. Also has good physical properties, is the best substitute for precious metals. Its economic and affordable, is the more recommended type of developing countries.
Third, precious metal porcelain teeth
Precious metal porcelain teeth: containing gold about 86%, so also known as gold porcelain teeth, excellent biocompatibility, stable metal properties, corrosion resistance, good metal ductility, very little gum discoloration. In addition, porcelain powder can reflect its own color on the surface of gold, making porcelain teeth more beautiful and fully meet the requirements of cosmetic restoration. Therefore, gold porcelain has both the beauty of full porcelain and the strength of metal porcelain teeth, is currently the most respected metal porcelain.
At present, most foreign countries make this type of porcelain teeth, suitable for front and back teeth. The disadvantage is that the price is more expensive.
Gold deposition technology porcelain teeth: containing about 99.9% gold, biocompatibility is excellent, but due to the complexity of the process, suitable for the production of front teeth, currently in the promotion.
Fourth, all-porcelain teeth
All-porcelain material has the advantages of aesthetics, color and shade close to the teeth, biocompatibility, so porcelain teeth rarely occur gingival discoloration, but its brittleness. At present, most of them are limited to the restoration of front teeth.
Recently, the successful development and application of zirconia all-porcelain, because zirconia all-porcelain teeth is through computer-aided design, laser scanning, and then computer-controlled grinding production, physical properties greatly improved to increase the toughness and hardness, some performance has exceeded the metal, is currently the most ideal all-porcelain and porcelain teeth.
Porcelain is a high-tech dental veneer method carried out in the last decade or so, not everyone is suitable. If selected properly, porcelain teeth have a realistic appearance, beautiful, strong and durable, color similar to natural teeth, both to restore the function of the teeth, but also to increase the role of aesthetics, is an ideal denture.
Good, higher service life of porcelain teeth should be composed of the following elements.
1, the physician should have a scientific design program;
2, dental preparation should be strictly standardized;
3, the material should be good;
4, the production technician level to be high;
5, the production of models to be accurate;
6, reasonable use.
Interlocking, mutual influence. So a tailor-made porcelain teeth can not only assume the normal performance of natural teeth, but also to maximize the reproduction of the natural beauty of human teeth.
