目的 观察Super -Band粘接剂对银汞合金充填体固位力的影响。方法 按一定的标准在临床上选择病例 ,分有固位型与无固位型两组 ,每组又随机分为实验组与对照组。治后定期随访检查。结果 在没有固位型的病例中 ,实验组中的银汞合金充填体未松动脱落率明显低于对照组 (P <0 0 1)。在有固位型的病例中 ,实验组与对照组的银汞合金充填体未松动脱落率没有显著性差异。结论 Super -Band粘接剂可以明显增强银汞合金充填体的固位力 ,起着类似倒凹、鸠尾相似的固位效果。
Objective To observe the effect of Super-B adhesive on the retention of amalgam filling. Methods According to a certain standard, patients were selected clinically. There were two groups of retentive and nonholonomic groups, and each group was randomly divided into experimental group and control group. Regular follow-up examination after treatment. Results In the cases without retention type, the shedding rate of amalgam filling in the experimental group was significantly lower than that in the control group (P <0.01). There was no significant difference in the looseness rate of the amalgam filling between the experimental group and the control group in the retentive cases. Conclusion Super-Band adhesive can significantly enhance the retention of amalgam filling, similar concave, dovetail-like retention effect.
