ABSTRACT
To study the effects of different post design on retention. 27 simulated tooth roots made of PMMA were divided into three groups, then manufactured the cement-expanded composite screw post-core system (CECSP), cement screw post-core system (CSP) and cast metal post-core system (CMP). The root and post-core system was tensiled by the speed of 10 mm/min on the Instron 4302 and recorded the retention force. It appeared significantly different between retention force of CECSP and CSP and CAM (P < 0.05). As a result, the retention mechanical properties of CECSP was much better than those of cement screw post-core system and cast metal post-core system. Therefore, it is possible to find a new way for restoration of endodontically treated teeth.
