Connectors are the components of a partial fixed dental prosthesis (FDP) or splint that join the individual retainers and pontics together. CONNECTORS Connectors types : • Rigid . J Prosthet Dent 2002:87:536-42. Tooth movements in divergent directions create stresses, that are transferred to the abutments & cause failure of the weaker retainer as the pier abutment act as a fulcrum. 3. J Dent Res 2002; 81:623-7. 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. google_ad_width = 728; It is a bridge in which the pontic is joined at one end to the retainer by a rigid connector, and the other end by a non rigid connector.

In the practice of fixed prosthodontics, certain situations like pier abutments, tilted abutments pose problems with rigid connectors. Angle Orthodont 1996;66:261-4. The occlusal forces on a fixed dental prosthesis are transmitted to the surrounding structures through pontics, connectors and retainers and more stresses are seen at the connector region. Nonrigid connectors take the form of male- and female-locking arrangements. Because of these dislodging forces rigid type of FPD with pier abutment have higher debonding rate than short span prosthesis, resulting in marginal leakage and caries .
