Mini-SG(R) F 冠外附着体在游离端义齿修复中对基牙牙周健康的影响

目的：观察Mini-SG（R）F附着体在游离端义齿修复中对基牙牙周健康的影响.方法：纵向观察Mini-SG（R） F附着体修复游离端缺失前后第一基牙、第二基牙牙周病常用指标及牙槽骨吸收情况的变化.结果：Mini-SG（R） F附着体在修复前、修复后6月内义齿稳定、固位良好,第一、第二基牙牙龈指数、菌斑指数、牙周探诊深度、牙槽骨吸收等差异均无统计学意义,修复前基牙的松动度在进行联冠修复后明显降低.结论：Mini-SG（R） F附着体在游离端义齿修复中对基牙牙周健康无明显不利影响,基牙的联冠修复形式有利于基牙的健康和稳定.

A pilot study on the effects of Mini-SG(R) F attachments on periodontal health of the abutment teeth used in free-end partial removable dentures

OBJECTIVE : To investigate the effects of Mini-SG F attachment on periodontal health of the abutment teeth in restoring free-end removable partial dentures (RPDs). METHODS : The periodontal status of the abutments in restoring free-end RPDs was longitudinally observed with periodontal indices commonly used in clinics, and a group comparison was made using a one-way analysis of variance (ANOVA). RESULTS: The stability and retention of free-end RPDs retained by Mini-SG F attachments were excellent during the whole observation course. Compared with the periodontal status of the first and the second abutments before restoration respectively, no significant differences in gingival indices, plaque indices, periodontal probing depth, alveolar bone resorption levels of those were shown 6 months after restoration. The mobility of the abutments was significantly reduced when they were splinted together. CONCLUSION: Mini-SG F attachments used in free-end RPDs have no evident adverse effect on periodontal health of the abutment teeth, and the way of splinting the abutments is advantageous to their long-term health and stability.
