DENTAL PROSTHESIS WITH PARTIAL METAL REINFORCEMENT

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dental prosthesis, and more particularly, to an opaque ceramic crown which is capable of enhancing the responsiveness to occlusal pressure and preventing the color of the entire teeth exposed to the outside from becoming cloudy and dark. The ceramic crown is formed so that the thermal expansion coefficient of the ceramic composition is close to the metal so that the ceramic crown made of a heterogeneous material and the partial metal The present invention relates to a dental prosthesis having a partial metal reinforcement portion which is capable of maintaining the color of a natural tooth while enhancing the physical properties of the dental prosthesis with metal.
