摘　　要：目的评价两种不同粘接水门汀对树脂类冠修复材料和全瓷托槽剪切粘接力的影响。方法选用2种水门汀Transbond XT和RelyX Ultimate,将上颌前磨牙全瓷托槽Inspire Ice与4种树脂类冠修复材料粘接。试件冷热循环5 000次后测量断裂载荷(N),并观察破坏形态。结果单因素方差分析结果F=4.52(P<0.001),显示粘接条件对陶瓷托槽和树脂类冠修复材料的剪切粘接力影响具有统计学意义。其中Lava Ultimate+Transbond XT组和Lava Ultimate+RelyX Ultimate+托槽喷砂组分别为(325.10±135.54)N和(304.71±35.71)N,较其他组高,Lava Ultimate+Transbond XT+托槽喷砂组最低,为(118.12±57.58)N。结论树脂基陶瓷材料Lava Ultimate和全瓷托槽的剪切粘接力较暂时冠修复材料高。全瓷托槽未喷砂时,正畸全瓷托槽粘接水门汀Transbond XT和修复用水门汀RelyX Ultimate的粘接力未见明显区别,喷砂后全瓷托槽失去固位小球,RelyX Ultimate有更高的粘接力。Objective To evaluate the effects of two different cements on shear bond force of resin crown restoration materials and all ceramic brackets. Methods Two kinds of cements, Transbond XT and RelyX Ultimate, were used to bond Inspire Ice with four kinds of resin crown restoration materials. The fracture load(N) was measured after 5 000 thermal cycles, and the fracture surface was observed. Results The results of one-way ANOVA, F= 4.52(P<0.001), showed that adhesive conditions had a significant effect on the shear adhesive force of ceramic brackets and resin crowns restoration materials. Among them, Lava Ultimate+Transbond XT group(325.10±135.54) N and Lava Ultimate+ RelyX Ultimate+ bracket sandblasting group(304.71±35.71) N were higher than those of other groups, and Lava Ultimate + Transbond XT + bracket sandblasting group was the lowest(118.12±57.58)N. Conclusion The shear bond force of the resin based ceramic material Lava Ultimate and ceramic bracket is higher than that of the temporary crown material. When the ceramic bracket is not sandblasted, there is no significant difference in the adhesive force between the orthodontic cement Transbond XT and the prosthodontic cement RelyX Ultimate. After sandblasting, the ceramic bracket loses the retention ball, and the RelyX Ultimate has a higher adhesive force.
