CLINICAL AND RADIOGRAPHIC EVALUATION OF FIBER AND METAL POST-CORE SYSTEMS: 5 YEARS FOLLOW UP

Aim: The aim of the study is to evaluate single crown restorations with different post-core systems clinically and radiographically. Material & Method: 145 patients treated in Marmara University Faculty of Dentistry was examined for this study. Fiber posts was applied 49 of these patients (60 teeth), while prefabricated metal posts were applied 96 of them (129 teeth). Results:A survey is applied to the patients to evaluate satisfaction, esthetic, phonetic, cleanability, retention and masticatory activity (0: bad 1: adequate 2: good 3: very good). General satisfaction is found 2.1 of 3 (%70) in prefabricated metal post patients. Some complications are seen in 29 of 129 of prefabricated metal posts. General satisfaction is found 2.3 of 3 (%76) in fiber post patients. Some complications are also seen in 13 of 60 of fiber posts. Using different type of adhesive cements do not affect the fracture resistance of the restorated teeth (p=0.209), and 10 mm post cavity depth showed greater fracture resistance than 5 mm cavity depth (p<0.001). Conclusion:With all the limitations of this study, depth of the post cavity will increase the fracture resistance of restorated teeth regardless of the type of adhesive cements
