Abstract

A dental implant assembly comprises a base member and an abutment member. The base member is adapted for placement into an opening in a jawbone and comprises elongated vertically parallel side walls coupled with opposing curved end walls which together define an eccentrically shaped external surface and an eccentrically shaped internal cavity. The base member also includes an eccentrically shaped curved lip which couples top edge perimeters of the external surface and the internal cavity to one another. The abutment member is adapted for placement into the eccentrically shaped internal cavity of the base member. Responsive to placement of the abutment member in the eccentrically shaped internal cavity of the base member, a trans-gingival emergence profile is formed between the eccentrically shaped curved lip and a region of the lower portion between the eccentrically shaped curved lip and the shoulder.

Due to their relatively low maintenance and their durability, people increasingly prefer implants to bridges or dentures. A dental implant assembly is configured to be positioned in an osteotomy cavity formed in a patient's jawbone. A base member of the implant is positioned into the cavity. The base member serves as a platform to secure an abutment member of the implant that in turn receives a dental restoration, such as a crown or denture. 3 BRIEF DESCRIPTION OF THE DRAWINGS [0007] A further understanding of the aspects of the disclosure may be realized by reference to the following figures.
