CONNECTORS IN FIXED PARTIAL DENTURES: A REVIEW
Fixed partial dentures (FPDs) are essential prosthetic solutions for restoring partially edentulous arches, with stability, aesthetics, and functionality. The design and choice of connectors, which bring retainers and pontics together, are crucial to the success of FPDs. The types, benefits, drawbacks, and clinical indications of rigid and non-rigid connections are reviewed in this article.Rigid connectors—such as cast, soldered, welded, and loop types—are preferred for cases requiring maximum load transfer to abutments, while non-rigid connectors—such as tenon-mortise, split pontic, and cross pin and wing—are indicated in complex cases involving pier abutments, misaligned teeth, or long-span prostheses.Appropriate connector choice, based on biomechanical and aesthetic considerations, is critical for the long-term success of FPDs.
