Abstract
Treatment carried out with a fixed partial denture (FPD) is one of the most accepted and desired by patients. However, it is a long procedure and cause high expectations from the patient. Once the clinician knows the factors that make dissatisfaction or related to failures, the dentist could reduce them and so meet all the patient’s need and set up the most suitable planning. The aim of this study was to evaluate the incidence of failures/clinical complications of the fixed prosthesis and to document the failure related factors that may affect the length of service of crown and fixed partial bridge (FPD) in Tripoli Central Dental Clinic/Libya. Also, the number of retainers, pontics, and the types of restoration were recorded. By examining 74 patients with 297 crown and bridge unites from the Tripoli Central Dental Clinic and collecting data related to the bridge area the data collated were subjected to descriptive analysis. A total of 74 patients were included in the study. Clinical evaluations of the patients were performed. Data were tabulated and patients with failure in prosthesis were calculated in percentage. The result of the study revealed that the pain was the most frequent complication observed on 56.8% of all the patients, under contour of the retainer has been found in 56.8% with an open margin in 73% and open proximal spaces with 48.6% of all subjects.
