A clinical survey to assess the correlation between the nature and type of failure in crown and fixed partial dentures

Objective: The purpose of this study was to evaluate the type of failure and nature of failure in crown and bridge prosthesis and to asses is there any correlation between type of failure and nature of failure in crown and fixed partial denture. Materials and Methods: Convenient judgement sampling of patients who reported to the department of prosthodontics with complain of failures in crown and fixed partial denture were selected for the study from 2013 - 2017. A sample questionnaire were prepared to collect relevant data. The percentage of crown and bridge failure was categorized and tabulated. Data was entered in excel sheet. SPSS version 17 was used to perform the analysis. Chi. square test was employed to find the association between type of failure in Crown and bridges type and between type of failure & nature of failure. Level of significance was set at 5%. Results: A clinical survey was conducted to determine the nature and type of failure in crown and fixed partial dentures. The result shows a significant association between type of failure and all crown types. [Chi. Sq. 22.2502 p=0.01] and significant association between type of failure and all bridge types [Chi Sq. 24.8624; P=0.005]. It also shows significant association between nature of failure and type of failure. Conclusion: Within the limitation of this survey, it was found that when the type of failure and nature of failures were analyzed there is a correlation between type of failure and nature of FPD failure.
