摘要：

背景：长期以来修复材料与基牙的黏接技术一直是口腔修复学的研究热点，其中尤为引人关注的是黏结工件的表面处理工艺。
目的：对比观察8种表面处理方法对Ceramage聚合瓷黏结强度的影响，筛选适合Ceramage聚合瓷的表面处理方法。
方法：将Ceramage聚合瓷制成试件80个，随机分成8组，分别采用喷砂，酸蚀，偶联剂，喷砂+酸蚀，喷砂+偶联剂，酸蚀+偶联剂，喷砂+酸蚀+偶联剂处理聚合瓷表面并与树脂黏结剂黏结，对照组不进行任何处理。在37 ℃水浴24 h后测试样本剪切强度，并用扫描电镜观察处理后的聚合瓷表面形貌。
结果与结论：各组的剪切强度值由高到低分别为：喷砂+酸蚀+偶联剂处理组(31.12±2.81) MPa，喷砂+酸蚀组(27.62±1.70) MPa，酸蚀+偶联剂组(27.31±2.18) MPa，喷砂+偶联剂组(26.91±1.97) MPa，喷砂组(24.23±2.03) MPa，偶联剂组(23.50± 2.19) MPa，酸蚀组(17.61±2.14) MPa，对照组(8.13±0.63) MPa，除喷砂组、偶联剂组之间，喷砂+酸蚀组、喷砂+偶联剂组、酸蚀+偶联剂组之间比较差异无显著性意义外(P > 0.05)，其余组间比较差异均有显著性意义(P  < 0.05)。结果显示7种表面处理方法都提高了黏结强度，喷砂、酸蚀联合硅烷偶联剂处理的聚合瓷黏结强度最高，是适合Ceramage聚合瓷黏结的表面处理方法。

Abstract:

BACKGROUND: Repair materials and abutment bonding technology have always been the research focus of prosthodontics, particularly surface treatment process.
OBJECTIVE: To observe the effect of six different surface treatments on Ceramage polymer-ceramic bond strength and to find the proper surface treatment method.
METHODS: Eighty polymer-ceramic specimens were randomly divided into 8 groups, respectively, using the following 8 ways: A: No treatment; B: Sandblasting; C: Etching; D: Silane coupling agent; E: Sandblasting + etching; F: Blasting + silane coupling agent; G: Etching + silane coupling agent; H: Sandblasting + etching + silane coupling agent bonded with Panavia- F resin cement. After storage at 37 ℃ water for 24 hours, the specimens were subjected to a shear bond strength test. Surface morphology of polymer-ceramic was observed using scanning electron microscopy.
RESULTS AND CONCLUSION: Shear strength values of 8 experimental group (MPa) from the highest to the lowest were as follows: H group (31.12±2.81), E group (27.62±1.70), G group (27.31±2.18), F group (26.91±1.97), B group (24.23±2.03), D group (23.50±2.19), C group (17.61±2.14), A group (8.13±0.63). There was no significant difference between B and D groups as well as among E, F and G groups (P > 0.05); the remaining groups were statistically significant between groups (P < 0.05). Seven kinds of surface treatment methods have increased the bond strength; Sandblasting group and Coupling group was significant higher than Etching groups; Sandblasting, etching in combination with silane coupling agent group showed the highest bond strength, which was the most proper surface treatment method for Ceramage polymer-ceramic bonding.
