碩士 === 中山醫學大學 === 口腔材料科學研究所 === 98 === In dentistry dental restoration mainly include the metal, the ceramics, the resin.Ti and its alloys are generally used for dental restorations, because of their corrosion, good mechanical properties, excellent biocompatibility, and the composite resin has the plasticity, easy operation, cheaper etc. The purpose of this study was to research the effects of surface treatments to strength on boning between titanium and dental resin, so we would like to improve the both bonding strength. The experimental result, Ti were heat treated at different temperature (700℃~800℃), the both bonding strength(three point flexure strength、Shear bond strength test) is better than the control group(49.41 MPa, 7.69 MPa), increases its along with the temperature for the both bonding strength to have the enhancement tendency, and then may obtain the good results by the short heat treatment time (70.45~77.63 MPa, 7.31~9.01 MPa).Then pre –Titanium, 700℃ group condition, were taken to immerse NaOH and H2SO4 solution , the experimental results present that immersion groups were not obvious difference for bonding strength. It is not obvious dropping tendency for bonding strength after thermocycling test running 6000 times. When thermocycline test run 20000 times, bonding strength have slightly the declining trend.
