Non Rigid Connector: A Boon for Pier Abutment Fixed Partial Denture--A Case Report UM Radke, NA Pande, SM Gundawar, Maithilee S Kolarkar, JIDA, Vol. 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. An innovative and cost effective way of fabricating a non-rigid connector is presented in this case report. The use of a rigid connector can lead to localization of forces on the pier abutment. Non-rigid connector placed on the distal aspect of pier seems to reduce potentially excess stress concentration on the pier abutment.
