There are many kinds of porcelain teeth on the market, many patients will ask the same question: "what kind of porcelain teeth should I choose?" today, we will introduce the types of porcelain teeth to you.
Porcelain teeth divided into metal and non metal ,from the perspective of structure, there are two parts, respectively is within the crown and the glazed ceramic layer, and the inner crown is divided into metal crowns and all ceramic crowns.
Here are some detailed introduction for you.
The metal porcelain teeth:
1. Ni Cr alloy porcelain teeth
Belongs to the porcelain base metal. The corrosion resistance of Ni Cr alloy, low price, chemical properties of Ni element is relatively stable in the oral environment, exposed metal will gradually decompose, precipitation of metal ions, leading to gingival tissue staining, the formation of gum black line. Not the mainstream products, now many dentists don't use it.
2.cobalt chromium inner crown porcelain teeth
Due to various problems of Ni Cr alloy porcelain teeth, cobalt chromium porcelain teeth are gradually produced. To abandon the "nickel" add, avoid saliva toxicity of nickel metal, nickel chromium alloy porcelain teeth is a substitute. Belongs to the porcelain base metal, in the aesthetic repair effect is just short of a young beauty. Friends do aesthetic restoration of anterior teeth, or not to use this material as much as possible.
3.silver alloy porcelain teeth
Silver containing more than 50% within the crown porcelain teeth. Its elasticity is moderate, good taste, and silver itself has a toxin absorption function, suitable for middle grade anterior teeth, crown protection, restoration of posterior strength is poor.
4.pure titanium inner crown porcelain teeth
Titanium metal has good biological safety, light weight, high hardness, stable performance, is the ideal material for oral cavity repair. Pure titanium metal is the only one not to react with the body, its biocompatible medical metal is the highest. The higher cost of precious metal ceramic restorations.
5.gold alloy crown porcelain teeth
Noble metal porcelain of the best simulation of high, comparable to that of natural teeth. Its good elastic buffer, strong, suitable for root short, poor bone teeth repair, in the crown before is the best choice for repairing of anterior teeth.
6.gold deposition baked porcelain teeth
Porcelain crown made by deposition, reducing a molding process, the fabrication error decreases. The aesthetic effect and sealing ability to repair anterior teeth restoration of posterior strength is poor.
Nonmetal Porcelain teeth
Non metal ceramic teeth are also called all ceramic teeth, divided into cast porcelain teeth and zirconia all ceramic teeth.
1. cast porcelain teeth
Cast porcelain is composed of ceramic material, the production process is to take a good impression, the whole cast, so the color is particularly realistic, but because there is no solid within the crown, so its not strong as the all ceramic teeth.
2.all ceramic teeth
All ceramic teeth production is the first to use porcelain material to burn the inner crown, and then fired on the outside of the porcelain powder.
Because of internal and external are belong to porcelain material, semi- transparency similar to natural teeth, after the restoration of the gingival margin expression more natural, can achieve the simulation effect, and durable. It is the preferred material for the repair of anterior teeth in aesthetics.
Advantages of porcelain materials:
Excellent biocompatibility with the human body, it will not stimulate the gums and cause gingival inflammation, gingival discoloration and other phenomena.
It has beautiful appearance, good translucent, and the effect is the most close to the natural tooth.
No noxious stimulation of the body, and had no effect on nuclear magnetic resonance imaging of the brain and neck.
