摘要
目的通过对两种冠外精密附着体的游离端第一基牙牙周指数的测定,比较两种附着体的冠外部分对基牙牙周健康的影响。方法选择肯氏Ⅰ类缺失的患者24例,每组12例,分别使用MK1精密附着体和Snap精密附着体修复,并在修复前、戴用3个月、6个月和12个月共四个时间段测量游离端第一基牙的菌斑指数、牙龈指数和龈沟出血指数,评定基牙的牙周状况。结果两组精密附着体的游离端第一基牙的牙周指数在戴用各时间段均明显高于修复前,MK1精密附着体组的牙周指数略高于同时间段的Snap精密附着体组。结论冠外附着体对游离端基牙的牙周健康有一定影响,临床医生在选择附着体类型时需根据基牙的牙周情况综合考虑。
Objective To evaluate the periodontal status of the free-end abutment teeth with two kinds of precision attachment-retained removable partial dentures. Methods Twenty-four patients with Kennedy I dentition defect were divided into two groups and restored by MK1 attachment or Snap attachment respectively. Periodontal indices were accessed at different stages. Results The periodontal indices of two groups after restoration were higher than those before restoration. The periodontal indices of the group using MK1 precision attachment were higher than those of the group using Snap precision attachment. Conclusion It is indicated that extra coronal attachment has adverse effect on free-end abutment teeth.
