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. Results: Von Misses stresses were observed at the connector region between the two pontics, especially in the cervical region. J Prosthet Dent 2002:87:536-42.

Augereau D, Pierrisnard L, Barquins M. Relevance of finite element method to optimize fixed partial denture design Part-I: Influence of the size of connector on magnitude of strain. Nonrigid connectors take the form of male- and female-locking arrangements. Furthermore, allowing physiologic tooth movement, it eliminates any hindrance as against a fixed restoration with all rigid connectors.

Rigid connectors are classified as either cast or soldered. J Prosthet Dent 1994;72:8-15. Their designing determines the health of periodontal ligament under FPD. 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. function RightsLinkPopUp () { var url = "https://s100.copyright.com/AppDispatchServlet"; var location = url + "?publisherName=" + encodeURI ('Medknow') + "&publication=" + encodeURI ('IJDR') + "&title=" + encodeURI ('Connector design in a long-span-fixed dental prosthesis: A three-dimensional finite element analysis') + "&publicationDate=" + encodeURI ('Mar 1 2013 12:00AM') + "&author=" + encodeURI ('Harshitha Gowda B H, Satish Babu C L') + "&contentID=" + encodeURI ('IndianJDentRes_2013_24_2_178_116673') + "&orderBeanReset=true" Choose this option using the Type drop-down menu in the Rigid Body section at the right half of the dialog.. • Loop connector.

Flexion charesteristics of four unit fixed partial denture framework using halographic interferometry. 3 Casted Connectors NON RIGID CONNECTOR Any connector that permits limited movement between otherwise independent members of an FPD. Objective: The aim of this study was to investigate the biomechanical interactions in tooth-implant-supported fixed partial dentures (FPDs) under several loading conditions with different numbers of splinted teeth and connector types (rigid and non-rigid) by adopting the three-dimensional (3D) non-linear finite element (FE) approach. Rigid Non RIgid. Quintessence Int 2004;35:820-5. We are at our place one of the leading supplier of Bakelite Connectors / Bakelite Strip Connector. Thus constitute an important part of FPD. BH Harshitha Gowda1, CL Satish Babu2 Oh WS, Gotzen N, Anusavice KJ. Non-Rigid Connector for Managing Pier Abutment in FPD: A Case Report. 5. This clinical report describes rehabilitation of a patient with FPD with pier abutment using semi-precision attachment. 3-unit fpd which replaces one missing tooth and so on. Finite Element Stress analysis on the effect of splinting in fixed partial dentures. CONNECTORS IN FPD. In the practice of fixed prosthodontics, certain situations like pier abutments, tilted abutments pose problems with rigid connectors. Material and methods. The cantilever fixed partial denture-a literature review. negative effects can be reduced by using a NON rigid connector (conventional , reverse inverted) NONrigid conventional connectors. The occlusal forces applied to a fixed partial denture (FPD) are transmitted to the supporting structures through the pontic, connectors, and retainers. The rigid and nonrigid connectors can increase the lifespan of an abutment in the five-unit FPD as it transfers less stress on the abutments. google_ad_height = 90; Int Assoc Dent Res 2003. Effect of connector design on fracture resistance of Al-ceramic fixed partial dentures. If rigid connectors are used in this situation, the pier abutment will act as a fulcrum because of physiologic tooth movement, arch position of the abutment, and the retentive capacity of the retainers. Connectors are the components of a partial fixed dental prosthesis (FDP) or splint that join the individual retainers and pontics together. google_color_url = "000000"; J Prosthet Dent 1992;68:564.
