Adhesive bonding of titanium was evaluated with a titanate primer and adhesive opaque resin. The primer consisted of 2% isopropyl dimethacryloyl isostearoyl titanate in methyl methacrylate. The adhesive was 4-META/MMA-TBB opaque resin that contained 4-methacryloyloxyethyl trimellitate anhydride and was initiated by tri-n-butylborane derivative. Titanium discs were machined and blasted with aluminum oxide. They were primed and bonded together with the opaque resin. A shear test was performed after repeated thermocycles for investigation of the durability of the bond. The shear strength of the primed and 4-META resin-bonded specimens was 37.2 MPa after 50,000 thermocycles, with only a small decrease in bond strength. This was significantly higher than the control values. Thus, titanate primer and 4-META/MMA-TBB opaque resin may be used for the bonding of titanium in prosthodontic practice.
使用钛酸酯底漆和粘结性不透明树脂对钛的粘结进行了评估。底漆由2%的异丙基二甲基丙烯酰基异硬脂酰钛酸酯溶于甲基丙烯酸甲酯中组成。粘结剂是4-META/MMA-TBB不透明树脂，其含有偏苯三酸酐甲基丙烯酸氧乙酯，并由三正丁基硼烷衍生物引发。将钛盘进行加工并用氧化铝喷砂处理。对其进行底漆处理后，再用不透明树脂粘结在一起。在反复热循环后进行剪切试验，以研究粘结的耐久性。经过50000次热循环后，经底漆处理并用4-META树脂粘结的试件的剪切强度为37.2MPa，粘结强度仅有小幅下降。这显著高于对照值。因此，钛酸酯底漆和4-META/MMA-TBB不透明树脂可用于口腔修复实践中钛的粘结。
