Occlusal Interferences In FPD Insertion Among Dental Undergraduates - A Questionnaire Study

Occlusal interference in Fixed Partial Denture(FPD) is one of the most common errors that occur during insertion. It can lead to the failure of the treatment and sometimes causes TMJ disorders. Hence the aim of the study was to evaluate the frequency of occlusal interferences in FPD among dental undergraduates. A questionnaire study was conducted among dental undergraduate students studying in a dental college in Chennai. A total of 100 undergraduate students participated. It consisted of questions regarding their practice and incidence of occlusal interference in FPD. The data was collected and analysed through IBM SPSS statistical analysis. Descriptive statistics was done. Percentages and frequencies were calculated and to test difference among variables the Chi-square test was done. In this study, 95% of students had come across occlusal interference during FPD insertion. About 45.26% of the students reported lower posterior as the most common site of occurrence on occlusal interferences. About 99% of the students reported articulating paper as the most common method of correcting this error. This study concluded that the occurrence of occlusal interference is higher among dental undergraduate students.
