Abutment
Pronunciation: AB-yut-ment
A tooth or implant fixture that serves as the primary support or anchor for a dental prosthesis such as a crown, bridge, or denture.
Full Definition
In dental practice management documentation, 'abutment' refers to a natural tooth, implant post, or prepared tooth structure that anchors and supports a fixed or removable prosthetic appliance. Editors must distinguish between abutment as a natural tooth (in bridgework) and as a manufactured titanium component placed on a dental implant. The term appears frequently in insurance narratives, lab prescriptions, and operative notes. Misidentifying the abutment type can result in claim denials. It is also used adjectivally, as in 'abutment tooth' or 'abutment crown.'
Usage
Usage note: Do not confuse with 'pontic,' which is the suspended false tooth in a bridge. Abutment is the support; pontic is the replacement.
