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. Therefore, the use of a non-rigid connector as a stress breaker has been advocated to alleviate the situation. 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. Together they form a unique fingerprint. 0000070610 00000 n Broken MK. When is an intermediate (pier) abutment used?
