目的：研究复合树脂对医用钛材和牙体硬组织的粘结性能。方法：用国产复合树脂ＥＢ和ＥＭ分别将国产纯钛（ＴＡ２）、钛铝钒合金（ＴＣ４）、钛－７５合金（Ｔ７５）粘结到牙釉质、牙本质上，通过剪切试验测得结合强度，对剪切试验后的试样断面进行观察、归类，分析断面破坏形式。结果：ＥＢ、ＥＭ对ＴＡ２、ＴＣ４、Ｔ７５和牙釉质、牙本质有较强的粘结力，结合强度达到了临床应用要求。结论：用ＥＢ、ＥＭ把ＴＡ２、ＴＣ４、Ｔ７５制成的牙修复体粘结到预备后的基牙上是可行的。
Objective: To study the bonding properties of composite resin to medical titanium and dental hard tissue. Methods: Domestic pure titanium (TA2), titanium-aluminum-vanadium alloy (TC4) and titanium-75 alloy (T75) were respectively bonded to enamel and dentin using the domestic composite resin EB and EM, Strength, shear section of the specimen after the test to observe, classify, analyze the fracture form. Results: EB and EM had strong adhesion to TA2, TC4, T75, enamel and dentin, and the binding strength reached the clinical application requirements. Conclusion: It is feasible to bond TA2, TC4, T75 dental prostheses to prepared abutments with EB and EM.
