Abstract

Shear bond strengths (SBSs) of seven kinds of resin-based luting cements (RLCs) to a polished cp titanium surface with 4 kinds of surface treatment (sandblasting, primer, and 2 kinds of tribochemical) were evaluated. SBSs of the unfilled-type RLCs containing functional monomers to the polished cp titanium surface were significantly higher than those of the composite-type RLCs (p<0.05). However, SBSs of the unfilled-type RLCs to cp titanium were not improved by the subsequent surface treatments. SBSs of the composite-type RLCs without containing functional monomers were significantly higher (p<0.05) than other RLCs when the primer was applied to the blasted surface (B-MDP). SBSs of the composite-type RLCs to the surface with tribochemical (TRB) treatments were almost equivalent to those with the primer treatment. These results suggested that the use of the composite-type RLC without functional monomers was effective to increase the adhesive performance of cp titanium with the surface treatments of B-MDP or TRB.
