前牙美观区即刻种植修复临床应用.docVIP

前牙美观区即刻种植修复临床应用[摘要]目的：探讨前牙美观区即刻种植与即刻修复的临床效果。方法：24例患者的31个牙位在拔牙同时植入种植体，5个牙位在拔牙后一周植入种植体，全部病例都作了种植后一周内的即刻修复，追踪观察6～28个月。结果：全部种植体稳固无松动，种植体周围无炎症，X线片未见明显骨吸收。结论：在适当选择病例的情况下，即刻种植与即刻修复可成功应用于前牙美观区。 [关键词]牙种植；即刻种植；即刻修复；美观区 [中图分类号]R783 [文献标识码]A [文章编号]1008-6455（2008）08-1205-03 Clinical application of immediate implant and restoration in aesthetic zone WANG Zhan,HE Yi-chuan,CHEN Wen-jun,YANG Wei-dong,HE Jie-ru,XIAO Jian (Department of Oral Maxillofacial Surgery, Dali Prefectural People’s Hospital, Dali 671000,Yunnan,China) Abstract: ObjectiveTo evaluate the clinical results of immediate implant and immediate restoration in aesthetic zone.MethodsTwenty-four cases were performed an operation of immediate implant for 31 dental implants as soon as the teeth of roots were extracted. 5 dental implants were implanted after one week of extractions. All cases were performed an operations of immediate restoration in one week and 6～28 month follow-up observation.ResultsAll dental implants were implanted successfully.
