This laboratory study evaluated the strength of composite repairs using various surface treatment procedures. Roughening a previously cured composite surface, with either a diamond instrument or aluminum oxide air abrasion, yielded composite to composite repair strengths that were not significantly different (P > 0.05) than bonding composite to the air-inhibited layer of a cured composite. The bond strengths of composite repairs were slightly higher when using an unfilled bonding agent but not significantly different (P > 0.05) than the same repair techniques without the bonding agent.
这项实验室研究评估了使用各种表面处理程序进行复合材料修复的强度。用金刚石器械或氧化铝空气磨蚀对先前固化的复合材料表面进行糙化处理后，复合材料与复合材料的修复强度与将复合材料粘结到固化复合材料的空气抑制层上的强度没有显著差异（P>0.05）。使用未填充粘结剂时，复合材料修复的粘结强度略高，但与不使用粘结剂的相同修复技术相比，没有显著差异（P>0.05）。
