ABSTRACT:
The object of this invention is to provide a pin-retained inlay bridge and process of making and fitting such a bridge to a patient. This inlay bridge (100) is firmly fixed to the abutment teeth (200) using a plurality of tapered pins (p) driven into the pinholes (220) of the teeth (200) through the locking holes (121) of the inlays (120) of the bridge (100) after bonding the inlays (120) to the inlay cavities (210) of the teeth (200). This bridge (100) thus minimizes the size of the inlay cavities (210). This bridge thus protects the abutment teeth, and prevents the abutment teeth from being decayed by food which gets stuck between the bridge and the abutment teeth. The present invention also simplifies the process of making and fitting such inlay bridges as well as reduces the operational cost during a dental treatment using bridges.
