Abstract

Aim: To evaluate abutments and status of FPDs of patients who asked for replacement of FPDs. Materials and Methods: A total of 115 people were who referred to Ege University, School of Dentistry, Department of Prosthodontics for the removal of their FPDs for various reasons participated. Their age ranged from 35 to 76 (53.98±8.55) years. The FPDs evaluated were as follows: 15 (13%) full metal crowns, 63 (54.8%) metal-acrylic bridges and 37 (32.2%) metal-ceramic bridges. The numbers of units, the location of restorations in the arch, the age and the type of restorations were recorded. The Modified United States Public Dental Health (USPDH)
criteria were used to evaluate the occlusion, and the Modified California Dental Association (CDA) criteria were utilized for evaluation of the clinical quality of restorations. Results: A total of 100 bridges with 727 units were examined, containing 464 abutments and 263 pontics. The mean age of FPDs was 6.53(±7.04) years for the crowns, 8.16(±9.28) years for metal-ceramic bridges, and 10.00 (±6.21) years for the metal-acrylic bridges. The mean age of FPDs was significantly higher in the metalacrylic group than in the metal-ceramic (p=0.017) and the full metal crown groups (p=0.015). The clinical assessment revealed that periodontal health (p=0.011), esthetics (p=0.000) and hygiene (p=0.002) were lower in the metal acrylic FPDs than in the other FPDs. The loss of proximal contacts were the highest in the metal-acrylic FPDs (p=0.003). Conclusions: Prior to the removal of FPDs, it was found, based on the CDA criteria, that, ‘unacceptable’ ratings of periodontal health, esthetics and hygiene were higher in the metal-acrylic FPDs than in the metal-ceramic and the full crown FPDs.
