Success rate of resin bonded restorative dentistry bridges

ABSTRACT

To assess the success rate of resin bonded bridges. Design: A descriptive cross-sectional study. Place and Duration of Study Fatima Jinnah Dental College Hospital, Karachi between August 1998 and August 2002. Subjects and Seventy resin bonded bridges fitted in 60 patients were clinically assessed for debonding. The inclusion criteria included minimal reduction of teeth with minimal occlusal contacts. Patients were excluded if teeth had a large discrepancy of space and heavy occlusion. The retainers were designed self retentive and covered the maximum tooth surface lingually and proximally. Impressions were taken and resin bonded bridges were fabricated and bonded. Information regarding the patient data, bonding and debonding was collected on a proforma and was analysed using SPSS version 10.0. Seventy resin-bonded bridges had been in place for an average of 33 months. The results showed a 94.3% success rate. Statistically significant results were found between anterior bridges and posterior bridges for bonding status [p<0.05]. Results were not significant where maxillary versus mandibular bridges were compared for bonding status. [p>0.05]. Resin bonded bridges achieved a high level of clinical success in the study
