Six systems (one polycarboxylate, one polymethyl methacrylate, one unfilled BIS-GMA resin, two combinations of methyl cyanoacrylate and polymethyl methacrylate, and one combination of unfilled BIS-GMA and filled composite resin) were evaluated for in vitro retention to acid-etched human enamel. Also tested were one unfilled-filled resin combination backed by perforated orthodontic band metal and another unfilled resin backed by stainless steel wire mesh. Significant differences in retention were found. Results show that retention depends pril surface and to resist subsequent chemical degradation.
对六种体系(一种聚羧酸盐、一种聚甲基丙烯酸甲酯、一种未填充的双酚 A 缩水甘油醚甲基丙烯酸酯树脂、两种氰基丙烯酸甲酯与聚甲基丙烯酸甲酯的组合,以及一种未填充的双酚 A 缩水甘油醚甲基丙烯酸酯与填充复合树脂的组合)进行了体外酸蚀人牙釉质保留率评估。还测试了一种由穿孔正畸带金属支撑的未填充 - 填充树脂组合以及另一种由不锈钢丝网支撑的未填充树脂。发现保留率存在显著差异。结果表明,保留率主要取决于表面,并能抵抗后续的化学降解。
