摘　　要：背景:精密附着体具有固位性强、美观性好、舒适耐用等特点,近年来已被应用于全口义齿修复中,球帽附着体和磁性附着体在下颌全口义齿中应用较多。目的:比较磁性附着体、球帽附着体和传统卡环固位体在下颌可摘局部义齿修复中的临床效果。方法:选择45例牙列缺损患者,分别行磁性附着体、球帽附着体和传统卡环固位的下颌可摘局部义齿修复,每种修复方式15例,3年随访患者的满意度及基牙牙周健康情况。结果与结论:磁性附着体组患者满意度中美观性、固位情况、咀嚼功能及舒适程度优于传统卡环固位组(P<0.05),球帽附着体组患者满意度中美观性、舒适程度优于传统卡环固位组(P<0.05),磁性附着体组患者满意度中固位情况、舒适程度优于球帽附着体组(P<0.05)。牙龈指数:磁性附着体组>球帽附着体组>传统卡环固位组(P均<0.05);基牙松动度:磁性附着体组<球帽附着体组<传统卡环固位组(P均<0.05);磁性附着体组、球帽附着体组牙周袋深度增加程度轻于传统卡环固位组(P<0.05);牙槽骨高度:磁性附着体组>球帽附着体组>传统卡环固位组(P均<0.05)。结果表明使用精密附着体固位的覆盖义齿较传统卡环固位的可摘局部义齿在临床疗效上具有一定的优越性;磁性附着体在修复下颌覆盖义齿时较球帽附着体具有一定的优越性,能够提供满意的固位力,更好地保护基牙牙周组织健康。BACKGROUND： Precision attachment has been widely used in complete denture because of its strong retention, good appearance, comfort and durability. Among them, magnetic attachment and ball-cap attachment are commonly applied for mandibular .complete denture. OBJECTIVE： To compare the clinical effects of magnetic attachment, ball-cap attachment and traditional clasp retainer used in the mandibular removable partial denture. METHODS： A total of 45 patients with dentition defects were included in this study, they were treated with magnetic attachment, ball-cap attachment and traditional clasp retention of mandibular removable partial denture. Fifteen patients received one means. The satisfaction of patients and the periodontal health of abutments were observed after 3 years. RESULTS AND CONCLUSION： Comparison of the patient satisfaction showed that, the aesthetics, retention conditions, masticatory function and comfort in magnetic attachment group were significantly better than traditional clasp retention group （P 〈 0.05）. The aesthetics and comfort in ball-cap attachment group were also better than traditional clasp retention group （P 〈 0.05）. There were significant differences on the retention conditions and comfort between magnetic attachment group and ball-cap attachment group （P 〈 0.05）. Gingival index was the highest in magnetic attachment group, then in ball-cap attachment group, and the lowest in traditional clasp retention group （P 〈 0.05）. The abutment tooth mobility degree was the lowest in magnetic attachment group, then in ball-cap attachment group, and the highest in traditional clasp retention group （P 〈 0.05）. The periodontal pocket depth in magnetic attachment group and ball-cap attachment group was lower than that in traditional clasp retention group （P 〈 0.05）. The alveolar bone height was the highest in magnetic attachment group, then in ball-cap attachment group, and the lowest in traditional clasp retention group （P 0.05）. Experimental findings in
