摘　　要：对1例Oehlers III型牙内陷伴有内陷结构周围炎的年轻上颌恒侧切牙,借助CBCT影像三维重建,在3D打印数字化导板辅助下,准确定位内陷部位并建立治疗通路,Vitapex糊剂充填内陷管腔。术后6月复查,内陷结构周围炎症消失、根尖孔缩窄、根管壁增厚。A young maxillary lateral incisor of Oehlers typeⅢDens invaginatus with peri-invagination periodontitis was reconstructed by CBCT,with the help of guided endodontics,the pathway to invagination was successfully established.The invaginated pseudo-root canal was treated with Vitapex mediation while preserving the pulp.After 6-month follow-up,the tooth was clinically asymptomatic.Radiological examination indicated complete healing of the peri-invagination lesion with narrowed open apex,and the thickened root canal wall.
