Abstract

STATEMENT OF PROBLEM: A secure bond between resin and an alloy framework is necessary for clinical success in removable prosthodontics. PURPOSE: This study compared the shear bond strength of composite to composite to metal with two commercially available chemical bonding systems: a silicoating system (Silicoater) and a nitrogenous heterocycle-acrylonitrile system (Kevloc). MATERIAL AND METHODS: Fifty-two nickel-chromium cubes were cast and composite resin was bonded to the alloy surfaces according to manufacturer's directions. After storage at 35 degrees C for 15 days, and thermocycling at 5 degrees C and 55 degrees C for 1200 cycles, the bonds were fractured in shear on a universal testing machine. RESULTS: Mean bond strength for the silicoated sample was 10.93 MPa and for the heterocycle-acrylnitrate system 11.44 MPa. An unpaired t test revealed no difference between the groups (p = 0.60). Visual inspection of the fracture surfaces revealed that failure was adhesive at the resin-to-metal surface in almost all the specimens.
