Abstract
Introduction: success of ceramic repair system is dependent on integrity of bond between ceramic and resin composite.
Aim: evaluate shear bond strength (SBS) of composite repair material to ceramo-metallic and zirconium restorations using new adhesive system after thermocycling.
Materials and methods: 28 square specimens of metal , zirconia , veneering porcelain for metal (VMK95) and veneering porcelain for zirconia (VM9) were prepared (1 x 1 x 0.5 cm) and divided into 4 groups: 1)metal (M) group , 2)zirconia (Z) group , 3)veneering porcelain for metal (VPM) group , 4)veneering porcelain for zirconia(VPZ) group). Then M and Z groups were sandblasted while VPM and VPZ groups were subjected to HF acid. Single bond universal adhesive were applied to exposed surface of all groups then repair composite material was built up incrementally over center of exposed surface using cylindrical teflon mold ( 3 x 5 mm), stored for 7 days in distilled water followed by 1000 thermocycles then SBS was tested.
Results: Highest SBS value between composite repair material and M group followed by Z group and composite repair material then VPM group and composite repair material then VPZ group and composite repair material.
Conclusions: Sandblasting and application of single bond universal adhesive containing MDP can be recommended for repair metal and zirconium surfaces with composite material. HF acid etching and application of single bond universal adhesive containing MDP can be recommended for repair VPM and VPZ with composite repair material.
