| Summary: | The use of a nonrigid connector (NRC) in a fixed partial denture having pier abutment increases the life of the prosthesis. Rigid connectors though most commonly used, result in early failure of the prosthesis such as debonding as well as put adverse effects on the abutments when used in the case of pier abutment. When prosthesis comes in function, the pier abutment acts as fulcrum, and high-stress concentration may occur at pier abutment ensuing in excessive displacement at terminal abutments. This case report presents rehabilitation of missing first premolar and first molar using NRC at the second premolar (pier abutment). |
