摘　　要：目的探讨应用种植体联合牙半切术单冠修复下颌磨牙的临床疗效。方法选择12例患牙,健康牙根完善根管治疗,微创拔除病变牙根。半切术后8～10周植入种植体,种植体植入后3～4个月进行种植二期手术,安装穿牙龈愈合基台。牙龈愈合4～6周后开始进行全冠修复,并随访2～4年。结果 11例种植体联合牙半切术单冠修复下颌磨牙均获成功,种植体稳固,种植体周骨组织未见明显吸收,修复体形态美观,功能恢复良好,患者满意度高。1例因病变的远中牙根与牙槽骨发生骨粘连,术中不得不使用骨凿损伤了近中牙根而一并拔除。结论种植体联合牙半切术单冠修复下颌磨牙是一种有效的修复方法。Objective To evaluate the clinical results of mandibular molar supported by dental implant and semitooth after tooth hemisection. Methods Twelve patients were included in this study, which received mandibular molar restoration by combination of semitooth and dental implant after tooth hemisection. The implant was placed in the position where the affected root had been extracted 8 to 10 weeks earlier. Finally, the crown supported by implant and semitooth was finished after 3 to 4 months. The cases were followed up for 2 to 4 years. Results Eleven cases were successful. The implant and semitooth were stable and no severe alveolar bone absorption was found. The restorded teeth functioned well. The clinical results were satisfactory. One case failed during extraction. Condusion The crown supported by dental implant and semitooth after tooth hemisection for mandibular molar is effective and feasible.
