Zirconium ceramic crowns

Zirconium ceramic crowns

The novelty of prosthetic treatment in Europe and USA is to replace metal-ceramic crowns classic (popularly known as crowns and porcelain) with ceramic crowns and Romania soon zirconiu.De support this type of work gain ground against traditional methods of coating teeth or dental implants. Keep in mind that although zirconium is a metal (very strong), its optical properties determine the natural aesthetics of the work, so after cementing them in the mouth, even dentists find it difficult to differentiate them from natural teeth. Basically, zirconium becomes the aesthetic support for ceramics, light reflectance mode is similar to that of a natural tooth.

Beneficial aspects of this material are determined by its properties:

• Total compatibility with mouth tissues, because zirconium is practically bio-inert, hence eliminating any possibility of an allergic reaction

• decrease the risk of damage to the dental pulp due to low thermal conductivity and limited Preparation of the tooth (dental substance requires minimal removal - enamel)

• sustainability work, due to increased mechanical resistance and total absence of corrosion in oral environment

• eliminating bad taste and marginal staining (phenomena present in conventional ceramic restorations with crowns), due impeccable marginal adaptation of zirconia ceramic works, as a result of using CAD / CAM technologies in implementing work on zirconium dental technician is assisted by computer technology, CAD / CAM (Computer Assisted Design / Computer Assisted Manufacturing) allowing faithful reproduction of the preparation made by the physician on tooth restored.

The difficulty is that the use of processing (grinding) teeth have made virtually no error because after the dental impression resulting model is subjected to scanning process and the resulting information is sent directly to the computer, any subsequent changes are no longer possible. It is therefore very important that your protetician have specialist experience in this type of work.
