【摘要】 目的:探索多根牙在半切术后的一种新的修复方式。方法:对11例患者的下颌病变磨牙施行了牙半切术和随后术区进行了牙种植体植入术。半年后采用保留的半牙和种植体共同支持的设计方式对磨牙进行单冠修复 ,并对患者进行了1～3年的随访和临床观察。结果:11枚种植体稳固 ,牙周及种植体周组织健康 ,修复体形态美观 ,功能恢复良好 ,患者满意度高。结论:多根牙的牙半切术结合牙种植术后的联合修复 ,最大程度地体现了“保存牙体组织”的治疗学原则和“避免对正常邻牙牙体组织的切磨”的种植学特色 ,是一种有效而值得推荐的治疗和修复方法。更多还原

Methods: Eleven mandidular molars from out patient were chosen,which had received root canal therapy and semisection.CDIC implant was inserted in the position that pathological root had been extracted 3 to 6 months later .Finally,a single crown co -supported by implant and semitooth was finished after half an year. Results: After 1 to 3 years follow-up, The implant and semitooth were stable ,loosing implant and severe alveolar bone absorption was not found.It demonstrated the high success rate(100%)of dental implant and satisfying restorated effect.
