Selected dental materials should look at the oral

With the continuous improvement of oral repair requirements, both functional and beautiful porcelain and ceramic restorations have become an increasing everyone's attention. However, the more types of porcelain teeth, porcelain teeth, patients do exist do not quite understand, I do not know how to choose. Make a brief introduction below.

A porcelain tooth is mainly divided into two kinds of base metal porcelain and precious metal ceramic. In the base metal and porcelain, nickel-chromium alloy and beryllium-containing Ni-Cr alloy porcelain tooth may be local gums stimulation, but have an adverse effect on the whole body, there is no scientific conclusion. Other base metals and ceramics, such as titanium, cobalt chromium alloy porcelain teeth, do not contain nickel and beryllium, less local irritation of the gums.

The precious metal ceramic gold alloy porcelain teeth (gold 86% to 88%, other elements, including platinum, palladium, etc.), other gold deposition porcelain teeth (gold 99.9%). Their good biocompatibility, and to stimulate the gums, what kind of specific applications, make a decision should be based on patients with different oral.

The all-ceramic dental oral fixed prosthesis developed in recent years, it does not contain any gold pigment, not only have excellent biocompatibility, and dental instruments has a good appearance, represent the future trend of non-gold factors of repair. All-ceramic dental clinical heat-pressed ceramic and CAD / CAM zirconia all-ceramic and so on. Heat-pressed ceramic aesthetics, but lower strength, usually used in front teeth. CAD / CAM zirconia all-ceramic, doctors completed the clinical tooth preparation and modulus, the latter part of the production process completed by computer design and CNC machine tool cutting, high precision, strength, theoretically can be used before and A variety of dental implant after dental restoration. Due to the limitations of zirconia crown color, aesthetics of CAD / CAM zirconia all-ceramic is slightly less than the heat-pressed ceramics. With the continuous improvement of the material, the problem is gradually resolved.
