Abstract
Objective To investigate the influence of different silane coupling agents to the shear bond strength of metal brackets bonded to porcelain surface. Methods 30 porcelain specimens were deglazed by water sandpaper and etched,rinsed with distilled water and dried before applying the silane primer.All specimens were divided randomly into 3 groups according to different silane coupling agents application,every group had 10 porcelain facets.30 metal brackets were bonded to ceramic specimens.All specimens were stored in artificial saliva bath at 37℃ for 24 hours.after brackets bonded for 60min,then the specimens were underwent shear testing with Instron universal testing machine. Results The shear bond strength of the groups treated with silane primer were higher than that without silane primer(P<0.05).There was not any statistically significant in the shear bond strength between the group of one-mix silane coupling agent and the group of two-mix silane coupling agent(P>0.05).The groups treated without silane coupling agent showed lower porcelain fracture than the groups treated with silane coupling agent. Conclusions Silane coupling agent can improve the shear bond strength between metal brackets and porcelain surface.There was not any statistically significant in the shear bond strength between the group of one-mix silane coupling agent and the group of two-mix silane coupling agent.关键词
