ABSTRACT:
Dental crowns, bridges and jointing implements or tabs for dental prostheses which are capable of being welded in the mouth are disclosed. These structures are preferably comprised of high purity titanium alloy. The dental crowns are formed as a cast or prepressed central cap in the shape of the tooth to be treated. The crown is additionally provided with one or two tabs which correspond to one or both of the linking sides of the crown with an adjacent crown. The titanium jointing tabs are designed for coupling and welding in the mouth and may be used with crowns or bridges of conventional structure such as gold or a gold alloy. Each jointing implement is provided at one end with a shaped element such as a screw to be rigidly coupled to the crown. The jointing implement is also optionally provided with one or more microindentations on the inside lateral surface to facilitate welding in the mouth with the jointing implement or tab of the crown element associated with the adjacent tooth.
