Question

A vital canine is to be used as the anterior abutment

of a four unit fixed partial denture and it has 2.0mm
remaining coronal tooth structure. The most
acceptable foundation restoration would be
A. bonded amalgam core build-up.
B. a pin retained amalgam core build-up.
C. a pin retained composite resin core build-up.
D. intentional devitalization followed by a post
and core restoration.

Answer 1

A pin retained composite resin core build-up would be the most acceptable foundation restoration in this case.

Step-by-step explanation:

n cases where a vital canine has limited remaining coronal tooth structure (2.0mm) and is chosen as the anterior abutment for a four-unit fixed partial denture, the most acceptable foundation restoration is a pin-retained composite resin core build-up. This technique involves strategically placing pins into the remaining tooth structure to enhance stability and retention. Subsequently, the tooth is built up using composite resin material, creating a durable and aesthetically pleasing foundation for the fixed partial denture. This approach prioritizes the preservation of natural tooth structure while ensuring sufficient support for the prosthesis, contributing to both functional and cosmetic success in anterior dental restorations.
