Introduction: Knowledge regarding the clinical complications that can occur in fixed prosthodontics enhances the clinician ability to complete a thorough diagnosis and develop appropriate treatment plan, communicate realistic expectation and plan for post treatment care. Numerous biological mechanical and esthetic factors should always be considered before commencing treatment. Unless due attention is given to the above factors failure in fixed partial denture is always a possibility
Methodology: A Cross- sectional study of 120 patients reporting (April 2019 to March 2020) to Department of Prosthodontics at Sri Sukhmani Dental College and Hospital Derrabassi with complaint pertaining to FPD were evaluated with questionnaire related to problem, duration for which prosthesis was in place along with clinical and radiographic examination
Result: Out of total 120 cases 60 percent of the failures were due to mechanical factors 34 percent due to biological and 6 percent due to esthetics. Of these78 percent of mechanical failure 50 percent of biological and 28 percent of esthetic failures were reported in less than 4 yrs. Note: SPSS 22.0 used for statistical analysis
Conclusion: Loss of retention was most frequent mechanical factor leading to failure Caries and periapical pathology were frequent biological factors for failures Unacceptable colour match and metal display were most common esthetic factor leading to failure Thorough understanding of biomechanical principles involved in FPD,desirable and acceptable manipulative skills along with critical eye and judgement are required for assessing details of treatment and subsequent prognosis
