Abutment selection for fixed partial denture is an important criterion for the success and longevity of the prosthesis. The forces acting on the prosthesis are dissipated along the abutments to the periodontal ligament. The major cause of failure includes inappropriate designing, taking improper materials for fabrication, insufficient tooth preparation, and not having enough knowledge regarding the biomechanics. Abutment selection for fixed partial dentures involves proper diagnostic ability and in-depth knowledge about the stomatognathic system. This article review about the diagnostic aspect and the factors influencing the abutment selection for a fixed partial denture, which aids in the long term success of the prosthesis.
