Abstract

Aims. This study aimed to assess the satisfaction levels of patients who had fixed dental prostheses for rehabilitation and analyze the aspects, including biological, mechanical, and aesthetic, that contribute to the failure of these prostheses. Material and Methods. Cross-sectional observational research was undertaken in the Department of Prosthodontics, College of Dentistry, University of Basrah, Iraq, from September 2022 to May 2023. The study included a cohort of 130 patients, both males and females, who received treatment with fixed dental prostheses. The participants who were selected answered a series of questionnaires on their concerns about the fixed prosthesis, and a clinical examination involving radiographic assessments of the prosthesis was conducted. The reason for failure was documented, and data were organized for descriptive analysis of the components assessed through chi-square and Fisher's exact test. Results. Based on clinical and radiographic assessment, it was determined that 103 out of the total number of individuals assessed experienced some form of failure. 44.6% of the cases exhibited biological problems, 31% exhibited mechanical failures, and 24.2% exhibited aesthetic problems. Dental caries accounted for most biological failures (32.6%), whereas prosthesis loosening was the primary mechanical cause of failure (56.2%). Poor marginal fit was identified as the leading aesthetic reason for failure (48%). A strong correlation was seen between the level of satisfaction and mechanical failure (p=0.017). Conclusion. Most patients expressed satisfaction following the observation period. Dental decay was the most prevalent biological component leading to failure, whereas loss of retention was the primary mechanical cause. In comparison to other aspects affecting aesthetics, poor marginal fit had a more significant role.
