Types and choices of dentures


When there are too many tooth defects or the adjacent surface has been destroyed, the shape of the tooth and the normal adjacency relationship cannot be restored by filling treatment (abnormal adjacency can cause food impaction), inlay repair can be selected. Inlay is a kind of prosthesis embedded in the cavity of the tooth to restore the shape and function of the tooth defect.

The production step is: first, the affected tooth is cut and ground into a certain shape of the cavity, and then according to the shape of the cavity, with different materials to make a completely consistent with the cavity of the restoration - inlay. After fitting, the inlay was adhered to the cavity with cement to restore the defect of the tooth tissue and the shape and function of the affected tooth to normal. Compared with the filling method, the intercalation can better restore the occlusal surface shape and adjacent surface contact.

The inlay system can be divided into metal inlay, hard resin inlay and porcelain inlay according to different materials. Metal inlays have good performance, robustness and durability, and are widely used. However, metal inlays are often used in the restoration of posterior teeth because of their color. Hard resin inlaid and porcelain inlaid color and human teeth color coordination, hard wear resistant, front teeth more applications.
