摘　　要：牙拔除后拔牙窝会发生显著的生理性萎缩改变。在前牙美学区,唇颊侧骨弓轮廓塌陷会严重影响种植修复的美学效果。为尽可能保存唇侧骨板,即刻种植有着严苛的适应证,绝大多数患者无法满足适应证要求。因此,本文通过文献回顾,总结拔牙窝唇颊侧骨板的萎缩性改变规律,并以此为生物学基础结合笔者的研究成果对即刻种植的适应证拓宽、临床术式及所使用的骨替代材料进行评述。After tooth extraction,significantly physiological atrophic changes would occur to the socket.In the aesthetic zone,the collapse of the labial/buccal bone contour could seriously affect the aesthetic outcome of implantsupported restorations.In order to preserve the labial bone,immediate implant placement has strict indications,which can hardly be met by the majority of patients.Herein,this article summarized the rule of atrophic changes in the labial/buccal bone of the extraction socket through literature review.Further,based on this biological rule and our research findings,the expanded indications,clinical surgical procedures,and bone substitutes used for immediate implant placement were reviewed.
