Abstract

The purpose of the current study was to evaluate the effect of functional monomers with phosphorus on bonding durability to titanium. Three metal conditioners (Alloy Primer, AP; Metal Link, ML; Eyesight Opaque Primer, EP) were assessed. The functional monomers for base metal are 10-methacryloyloxydecyl dihydrogenphosphate (MDP) for the AP, 6-methacryloxyhexyl phosphonoacetate (MHPA) for the ML, and methacrylatephosphate (MP) for the EP. Cast disk specimens made of high-purity titanium (T-Alloy H) were air-abraded with 70μm alumina, primed with three conditioners, and then bonded with an acrylic resin adhesive (Super-Bond C&B). Shear bond strengths were determined both before and after thermocycling (20, 000 cycles).<BR>Before thermocycling, the shear bond strengths for the AP and ML groups were significantly higher than those for the EP and unprimed (defined as control) groups (p<0.05). The AP group exhibited significantly higher bond strength than the ML group after thermocycling (p<0.05). Significant difference was not found between the EP and the unprimed groups regardless of thermocycling application (p>0.05).
