Commonly observed complications associated with a conventional fixed partial denture (FPD) include loss of retention and tooth fracture. This report describes the occurrence of an unusual FPD abutment fracture and subsequent treatment. The distal abutment of an FPD developed severe periodontal disease with mobility. The anterior abutment fractured in the middle of the clinical crown and experienced cement failure.
An often-neglected aspect of fixed prosthodontics is the contour of the tooth adjacent to the cast restoration. The adjacent surfaces should be surveyed to reveal compatibility with the path of insertion of the restoration. Adjacent contacts may have to be altered to permit the placement of the fixed partial denture and to ensure proper contact size/shape and embrasure size. The need for guide planes on teeth adjacent to fixed partial denture abutments in fixed prosthodontics is described.
