  • Patent number: 4594069
    Abstract: A dental crown (cap) remover with unique crown separating and removing means is adaptable to a wide variety of crown sizes and configurations and does not place compressive or axial forces on the underlying tooth or its supporting processes (alvoelar bone and periodontal fibers). The crown remover has a grasping and tightening mechanism that allows the dentist operator to firmly seat the crown remover on the crown to be removed, and has an elliptical separating mechanism that inserts in a precut groove in the crown and forces separation of the halves of the crown, increasing the circumferential dimension breaking the cementing medium and loosening the crown from the underlying tooth, providing for ease of separation of the crown from the tooth.
