Proximal contour modifications for fixed partial dentures: A clinical report

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.
