Convergence Angle of Prepared Typodont Teeth for Full Veneer Crowns Achieved by Dental Students

This study measured the convergence angles of typodont tooth preparations for full veneer crowns prepared by students in Faculty of Dental Medicine, Sofia, Bulgaria. The convergence angles of tooth preparations for full veneer crowns were evaluated to achieve the objective of the study. Sample of 80 typodont teeth (20 upper premolar, 20 lower premolar, 20 upper molar and 20 lower molar) prepared by third year dental students at the Faculty of dental medicine were collected. The bucco-lingual convergence angles of each preparation were measured with the help of software MB-Ruler. Mean convergence angles were calculated, and differences between groups were tested for statistical significance with Independent sample t-test at 5 % level of confidence. The mean values for premolars and molars differed significantly. Convergence angle measurements were significantly different between the two groups teeth (p
