Furthermore, allowing physiologic tooth movement, it eliminates any hindrance as against a fixed restoration with all rigid connectors. J Prosthet Dent 1994;72:8-15. Clinical Significance: The occlusal forces on a fixed dental prosthesis are transmitted to the surrounding structures through pontics, connectors and retainers with maximum stresses concentrated at the connectors. The bonhomie of rigid and nonrigid connectors can increase the lifespan of an abutment in 5-unit FDPs as it transfers less stress on the abutments.

Close Type Connectors 5 / 10 / 15 / 30 Amp. A 3-dimensional cross-section FEM model (SAP 2000) simulating a 5-unit metal ceramic FPD with a pier abutment with rigid or nonrigid designs (connector location at the mesial region of the second molar, at the distal region of the second premolar, at the mesial region of the second premolar, and at the distal region of the canine) was developed. Some way must be use to neutralise the outcome of those forces. 3. Rigid-Flex PCB vs. In this prosthesis, the movement of the nonrigid connector is enough to prevent the pier abutment from serving as a fulcrum. Hence this three-dimensional finite element analysis study investigated stress distribution in a four unit posterior fixed dental prosthesis, having cylindrical and triangular connector designs. The technique used is simple, economical, and feasible in an ordinary laboratory set up. The N-type RF connector is larger than the BNC connector and it has a threaded coupling interface to ensure that it mates correctly. J Prosthet Dent 1999;81:721-8.
