FPD with difference in connectors: A case report

Abstract

The durability and long term performance of a Fixed Partial Denture (FPD) largely depends on the type of occlusal relationship, area of missing teeth, distribution of stress, alveolar bone loss and condition of the periodontium. The prosthetic reclamation of a posterior FPD with pier abutment is always considered as a challenging task for a dentist due to frequent fracture of posterior FPD in connector region during functional occlusal loading. The frequent use of rigid connectors in day to day practice in such situations results in failure and instability of the prosthesis. In pier abutment areas, replacement of rigid connectors with non rigid connectors during fabrication of an FPD makes a huge difference in the long term mechanical behaviour of posterior fixed dental prosthesis. So, depending on the clinical scenario, accurate prior selection of type of connector by dentist makes the real difference in the overall prosthetic overhaul of the prosthesis. This clinical case report explains the simple basic technique of incorporation of non rigid connector to restore such cases.
