Tooth preparation design for anterior abutments of resin-bonded fixed partial dentures: a technical report.
One challenged associated with the placement of maxillary resin-bonded fixed partial dentures (RBFPDs) that include anterior abutments is creating an effective preparation design to ensure mechanical retention of the dentures and anterior-guided occlusion. This article presents a methodical preparation design for anterior abutments of RBFPDs. One innovative feature involves extending the reduction to part of the occlusal wear facets. This design makes it possible to preserve the patient's innate occlusal function and to hold the retainer firmly by means of applied occlusal force.
