Clinical audit of posterior three-unit fixed-movable resin-bonded fixed partial dentures - A retrospective, preliminary clinical investigation

摘要

Background: Two-unit cantilevered resin-bonded fixed partial dentures (RBFPDs) have higher retention rates over longer span fixed-fixed RBFPDs. It has been hypothesized that interabutment stresses associated with fixed-fixed designs cause prosthesis debonds therefore for the replacement of molar sized and longer spans, non-rigid connectors have been used to allow independent movement between two abutment teeth.
