  • Tooth replacement assembly, and method
    Patent number: 5458489
    Abstract: A prefabricated tooth replacement assembly includes a cap adapted to be secured upon an abutment, a replacement tooth for occupying a void in the patient's mouth, and an interlock for supporting the replacement tooth from the cap in a selected position of adjustment relative thereto. The interlock is provided by forming an opening in the replacement tooth, forming a lateral protrusion on the cap, and selecting the configuration of the parts such that the protrusion from the cap frictionally engages the opening in the replacement tooth. Further, the replacement tooth is made at least partially hollow, and the protrusion from the cap extends into its hollow interior and is then locked in place by bonding material filling the hollow interior.
