3种正畸粘接材料垫高后牙咬合成功率的研究

摘要

目的：比较3种正畸粘接材料垫高后牙的成功率。方法选择正畸科就诊患者189例，共480颗牙作为研究对象，分别使用玻璃离子、GC Fuji LC、Resilience 3种粘接材料垫高后牙咬合，随机分为3组，每组160颗牙。A组使用玻璃离子，B组使用GC Fuji LC，C组使用Resilience。临床观察6个月，统计3种材料的脱落情况及成功率。结果 Resilience的成功率为96%，GC Fuji LC的成功率为87%，玻璃离子的成功率为75%，三者间的差异有统计学意义（P<0.05）。结论3种垫高后牙材料的脱落情况及成功率存在显著差异。%Objective  Compare the success rate of 3 different types of orthodontic adhesives as occlusive pad. Methods One hundred and eighty-nine patients, with a total of 480 teeth were evaluated, 3 different types of orthodontic adhesives were applied as occlusive pad. The sample were randomly divided into 3 groups, 160 teeth per group. Group A used glass ionomer cements, group B applied GC Fuji LC, and group C used Resilience. We followed up for 6 months, and compared the detachment and success rate of orthodontic adhesives. Results  The success rates of Resilience, GC Fuji LC and glass ionomer were 96%, 87%, 75%, respectively, presenting significant statistical difference(P<0.05). Conclusion  Significant differences existed among 3 orthodontic adhesives in terms of detachment and success rate.
