ONE-PIECE SINGLE-STAGE DENTAL IMPLANT AND SINGLE-STAGE DENTAL IMPLANT SYSTEM

摘要

A single-stage dental implant (10) for installation in living jawbone (14) having a ridge (18) that is covered by gingival tissue (20) is set forth. The dental implant (10) provides an artificial root on which a dental prosthesis is mounted to replace a missing tooth which formerly emerged from the jawbone. The single-stage implant comprises an anchoring portion (12) for extending into and integrating with the jawbone and an integral gingival section (16) that extends beyond the ridge of the jawbone. A seating surface (36) is located within the gingival section (16) and above the gingival tissue so as to be exposed after the implant is installed in the jawbone. The seating surface engages the dental prosthesis as the dental prosthesis is held thereon by a screw (160). The gingival section is contoured to replicate the natural emergence profile of the missing natural tooth. The prosthesis may extend axially from the implant or at an angle with the implant axis.
