Author(s): Sai Teja Reddy M, Subhabrata Maiti* and Keerthi Sasanka

Purpose: The aim of this study was to retrospectively evaluate the various types of finish line configuration given on different teeth for patients undergoing fixed dental prosthesis treatment.

Materials & Methods: A total of 996 patient data were taken from 86000 of patient data after reviewing, duplicate and missing entries were omitted. So a total of 722 entries were evaluated. The data was collected from patient records in Saveetha Dental College, over a period of one year. The evaluation was based on the type of finish line configuration given by the dental students, both the undergraduates and postgraduates in their fixed dental prosthesis cases.

Statistical Analysis: The results of the study were subjected to statistical analysis. Data analysis was done using SPSS software version 23.0. Chisquare test and frequency evaluation was done to evaluate the most frequently used finish line configuration.

Results: It was found that the shoulder finish line was widely used followed by chamfer finish line configuration. p=.193(p>0.05), although is statistically not significant and indicates strong evidence for the null hypothesis the trend is towards shoulder finish line.

Conclusion: The present study concluded that most of the dental students preferred shoulder finish line configuration followed by chamfer, knife edge and the least frequently used finish line configuration is feather edge and radial shoulder on the tooth surface for their fixed partial dental treatment. The trend is towards shoulder finish line mainly because of esthetics and zirconia as a material of choice.
