摘要
目的探讨磁性附着体与冠外附着体联合应用的临床效果。方法对22例多数牙缺失伴残根残冠的患者,采用磁性附着体与冠外附着体联合修复治疗,随访2～4年,调查患者对义齿使用的满意情况,以及基牙和修复体的情况。结果患者对义齿的咀嚼功能、稳定性及美观性均满意。临床检查未发现基牙松动及继发龋,1例患者出现基牙周围骨吸收,5例患者出现基牙牙龈炎,1例患者修复2年后出现咀嚼痛,5例患者2年后出现义齿松动,经对症处理后义齿均继续正常使用。结论对于多数牙缺失并伴孤立残根残冠的患者,采用磁性附着体与冠外附着体的联合修复可获得良好的临床效果。
Objective To explore the clinical effect of combined application of magnetic attachments and extracoronal attachments in prosthodontics. Methods Twenty-two cases of dentition defect with isolated residual root or residual crown were selected.

Chewing pain occurred in 1 case and unstable state of dentures appeared in 5 cases after the use of denture for 2 years.
