摘要： 目的: 探讨Vitallium双重大连接体支架式义齿在Kennedy Ⅰ、Ⅱ类牙列缺损修复中的应用效果。方法: 按纳入标准选取30例Kennedy Ⅰ、Ⅱ类牙列缺损病例,游离端近中基牙松动在Ⅱ度以内且牙槽骨吸收不超过根长的1/2,进行Vitallium双重大连接体支架式义齿的设计制作,戴牙后6个月和12个月分别进行游离端近中基牙评估（牙龈指数、松动度、X线、牙周探诊深度）,并在戴牙1年后进行患者满意度调查,比较各指标的差异,采用SPSS18.0软件包进行统计学处理。结果: 30例双重大连接体支架式设计的患者游离端近中基牙的牙龈指数、松动度、X线表现在戴牙后6个月和12个月均未出现明显变化,牙周探诊深度在戴牙初期与戴牙后无显著差异（F=0.0046,P=0.9954）。患者义齿戴用1年后的满意度较高,尤其是美观程度（93.33%）与舒适性（86.67%）。结论: 双重大连接体支架式义齿对游离端近中基牙有一定保护作用,尤其是基牙牙周状况不佳者,且患者戴用后满意度较高,可作为游离端牙列缺损可摘局部义齿修复的一种常用设计方案。

Abstract: PURPOSE: To study the clinical effect of Vitallium removable partial denture (RPD) with dual major connector (DMC) in rehabilitation of Kennedy Ⅰ and Ⅱ dentition defect. METHODS: A total of 30 patients with Kennedy Ⅰ and Ⅱ dentition defect fitting to the inclusion criteria were selected and restored with Vitallium RPD with DMC. Patients were re-called at the 6th and 12th month for clinical follow-up examination of gingival index (GI), abutment teeth mobility (TM), X-ray imaging, probing depth (PD) and satisfaction surveys. Then the differences of each index were analyzed with SPSS 18.0 software package. RESULTS: GI, TM and X-ray features of free-end abutment teeth in 30 clinical cases had no obvious changes either at the early 6-month or at the later 12-month, and PD had no significant difference, either (F=0.0046, P=0.9954). Satisfaction surveys showed high satisfaction, especially in the respects of aesthetics (93.33%) and comfort (86.67%). CONCLUSIONS: From this study, it is concluded that Vitallium RPD with DMC have certain protective effect on the free-end abutment teeth, especially with the poor periodontal condition. It also shows high rate of patients' satisfaction. Therefore, it can be used as one of the common designs of RPD in cases of free-end dentition defect.
