Fixed dentures are composed of three parts: retainer, bridge and connector.
Retainer refers to the part of the structure fixed on the abutment, including full crown, post and core crown, partial crown, inlay, wing plate fixed bridge, etc., and is connected with the abutment by the retention force and obtains retention. Among them, intra-crown retention is commonly used. The bridge is connected to the abutment by the retention of the retainer and transmits the occlusal force to the abutment through the retainer. Therefore, the retainer should have good retention and resistance.
A pontic, an artificial tooth, is the part of a fixed bridge that restores the form and function of a missing tooth.
The connecting body is the connecting part between the bridge body and the retaining body, and can be divided into fixed connection and non-fixed connection according to different connection methods.
