A COMPARATIVE STUDY OF SHEAR BOND STRENGTH OF REPAIRED FUSED METAL RESTORATIONS AND INTERFACE ADAPTATION USING 3 DIFFERENT COMMERCIALLY AVAILABLE REPAIR MATERIALS
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2016, Vol 5, Issue 65
Abstract
BACKGROUND The fracture of Porcelain Fused Metal restorations is one of the common clinical situation that occurs in routine clinical practice. Repair of fractured metal ceramic restoration can be done to reestablish the function and the aesthetics of restoration. The clinical success of ceramic repair is almost entirely dependent on the integrity of the bond between the ceramic-metal substrate and composite resin. AIM To evaluate the shear bond strength of repaired porcelain fused metal restorations by using different types of commercially available composite restorative materials. To assess the closer adaptation of composite and the ceramic at the fracture interface. MATERIALS AND METHODS The study was conducted on 43 test samples with 10 samples in control group and 11 samples in each of the three test groups (Ivoclar, 3M, Dentsply). Out of 11 samples in each test group, 10 samples were tested for shear bond strength using Lloyd’s Universal Testing Machine (Floor type) and 1 sample was tested for bonding interface adaptation. RESULTS Results obtained shows that the shear bond strength exhibited a mean value of 24.08 for group A, 9.14 for group B, 8.24 for group C and 6.27 for group D. Maximum value of shear bond strength of composite restorative material with porcelain and the metal substructure were obtained with group B (Ivoclar) followed by group C (3M) and group D (Dentsply). Bonding interface adaptation was closer for Ivoclar composite restorative material than other materials. CONCLUSION The result of the study shows that Ivoclar composite restorative material could provide better bond strength and bonding interface adaptation as compared to other repair materials. However, further longitudinal studies under conditions simulating the oral environment are needed to prove the success and longevity of ideal composite repair material.
