Abstract
The present inventions is an abutment for use with a dental implant. The abutment comprises a prosthetic portion adapted to support a prosthesis thereon and an insert. The prosthetic portion has a subgingival end and a supragingival region for protruding beyond gingiva adjacent to the dental implant. The prosthetic portion has a passageway extending therethrough. The passageway includes an enlarged retention groove and non-round section. The insert extends into the passageway and engages the subgingival end of the prosthetic portion. The insert includes flexible retention fingers that, upon insertion into the passageway, initially contract before reaching the enlarged retention groove and then expand outwardly into the enlarged retention groove to hold the insert onto the prosthetic portion. The insert also has a non-round section for mating with the non-round section of the passageway.
