Introduction: Fixed dental prosthesis are becoming more popular for preservation of badly damaged crowns or endodontically treated teeth and also for replacing the lost or missing teeth not only in the developed countries but also in the developing countries across the world. Objectives: The main objective of the study is to find the failure of prosthesis in fixed prosthodontics among patients. Material and methods: This cross sectional study was conducted in de'Montmorency College of Dentistry, Lahore during June 2019 to December 2019. The data was collected from 100 patients. The data was collected through non-probability consecutive sampling technique. Results: The data was collected from 100 patients. There were 40 females and 60 males and the mean age was 43.45±2.56 years. The most common reason for replacement of multi-unit fixed dental prostheses were periodontal diseases affecting 92.8% of restorations, followed by defective margin in 90.4% of examined restoration, poor esthetic in 88% of restorations, while periapical involvement was found in 85.5% of examined fixed dental prosthesis. Conclusion: It is concluded that the most common complications of fixed dental prosthesis were dental caries, decementation of crowns, periapical lesions, esthetic problem, coronal or radicular abutment fracture on patients using the prosthesis for one to five years.
