A Retrospective Marginal Fit Evaluation Of A Fixed Dental Prosthesis Framework Fabricated By Various Dental Students

The aim of this study was to retrospectively evaluate the marginal fit evaluation fabricated by various dental students. A total of 570 data entries were taken, duplicate and missing entries were omitted. So a total of 60 entries were evaluated. The data was collected from private dental records for the purpose of preservation and efficient analysis of the patients' details over a period of one year from June, 2019 to March, 2020. The evaluation was done by radiographic evaluation and checked for horizontal and vertical fit. The results of the study were subjected to statistical analysis. Data analysis was done using SPSS software version 23.0 Chi-square test and frequency evaluation was done to evaluate the marginal discrepancy of various teeth from the selected samples. It was found that over contouring or under contouring was more evident in lower posterior restoration. Vertical discrepancy was equally seen in all examined teeth. Association between the location of the teeth, horizontal fit and vertical fit was found to be statistically not significant. (p>0.05).
