A comparative study of some retention factors of teeth preparation between Damascus University and International University for Science and Technology

Abstract

The aim of this study was to evaluate and compare the total occlusal convergence of prepared teeth between Damascus University and International University for Science and Technology. The sample consist of 150 cast of prepared teeth from fixed prosthodontics clinic in Damascus University, and 127 cast of prepared teeth from the fixed prosthodontics clinic in International University for Science and Technology.

The mean value of taper degree of Damascus University samples was (8 degrees), while it was (8.7 degrees) in the international university for science and technology, also the anatomic features of occlusal surface were detectable and sufficient in both universities samples. In addition, the knife edge finish line was the most type used in both universities.

Although the treatment plan maybe different at both universities, but our study recommended the importance of total occlusal convergence, occlusal surface, and finish line of prepared teeth to provide retention and success of fixed prosthesis.
