Comparison of Shear Bond Strength of Two Porcelain Repairing System (Ivovlar Vivadent Repair System and Shofu Inc. Repair System)

Abstract

Background: Dental ceramics are materials that are part of systems designed with the purpose of producing dental prostheses that in turn are used to replace missing or damaged dental structures. The present study was undertaken for comparing the bond strength of two porcelain repairing system (Ivovlar Vivadent repair system and Shofu Inc. repair system).

Materials & methods: A total of 20 specimens were included in the present study and were divided broadly into two study groups with 10 specimens in each group: Group A: P & R Repair Kit, Shofu, and Group B: Ceramic Repair N system Ivoclar. A total of 20 base metal alloy discs were prepared. To prepare 20 discs of base metal alloy of 10mm in diameter and 0.5 mm thickness, wax patterns  were fabricated for standardization of metal thickness of 0.5 mm and porcelain thickness of 2 .0 mm. Universal Testing Machine was used. Data obtained were entered into MS Excel spread sheet and the statistical operations were carried out through Statistical Presentation System Software.

Results: Mean shear bond strength of specimens of Group A and Group B was 12.45 and 17.39 MPa respectively. While comparing the mean shear bond strength between group A and group B, significant results were obtained.

Conclusion: Ceramic Repair N system Ivoclar enhances the shear bond strength between intraoral repair materials and the surface of fracture metal-ceramic restoration.
