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, the cover screw 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. The healing cap is then removed and replaced by an abutment having an emergence profile matching that of the healing cap. An immediate snug fit between the gingival tissues and the abutment is thereby provided at the time of connection of the abutment to the fixture. A crown is removably attached to the abutment by a screw extending through the side of the crown into the abutment. An improved version of the healing cap is a healing cap created in two portions so that one portion around which gingiva tissue regrows remains in the patient and only a second upper portion is removed, and an improved abutment which is engageable with the portion of the healing cap left in the patient is used for the abutment about which the crown is removably attached.
