  • Patent number: 5145372
    Abstract: A system and method is provided for implanting tooth analogues in the jawbone resulting in aesthetically and functionally desirable gingival tissue contours after restoration. The system permits modification and adaptation of the tooth analogue to meet intraoral demands in a manner similar to that used in the preparation and restoration of natural teeth. The system comprises a standard fixture and cover screw passed through opened gingival tissue and implanted in the jawbone. After the osseointegration of the fixture, the gingiva is reopened and the cover screw is removed, and a healing cap having a predetermined contour is attached to the fixture. The reopened gingiva re-heals in a shape determined by the contour of the healing cap.
