Abutment
Pronunciation: AB-yut-ment
The intermediate connector component that attaches to the implant fixture and supports the overlying prosthetic crown or restoration.
Full Definition
In dental implantology, the abutment is the transmucosal element that links the subgingival implant fixture to the supragingival prosthetic component. It may be prefabricated (stock) or custom-milled, and can be made of titanium, zirconia, or gold alloy. Editors frequently encounter the term in prosthetic and surgical case reports, and must not confuse it with the use of 'abutment' in fixed prosthodontics, where it refers to a natural tooth used to anchor a bridge. Context is essential for disambiguation.
Usage
Usage note: Clarify whether 'abutment' refers to an implant abutment or a natural-tooth abutment for a bridge; the two are distinct concepts.
