摘　　要：上颌阻生第三磨牙多位于上颌结节区,此区域手术操作空间小、视野差。本文报道1例牙冠位于邻牙两牙根之间、与上颌窦关系密切的上颌水平超高位阻生第三磨牙的拔除。利用数字化模拟技术三维重建患者部分上颌骨、相关牙齿等毗邻解剖结构,精准制定最佳手术方案,采用牙根先脱位、牙冠后脱位法拔除阻生牙。该法既保护了邻牙牙根,也降低了上颌窦黏膜损伤以及穿孔的风险,提高了手术效率,减小了手术创伤,符合微创牙槽外科理念,为临床上拔除此类埋伏阻生牙提供了新思路和经验。Most of the maxillary impacted third molars are located in the maxillary tuberosity,where the vision and operation space are limited.This paper reports a case of surgical extraction of the left maxillary horizontal superhigh impacted third molar,which is located between the roots of the adjacent teeth and is closely related to the maxillary sinus.The digital simulation technology was used to reconstruct a three-dimensional visual image of the patient’s maxilla,related teeth,and other adjacent anatomical structures to assist in finding the optimal surgical method accurately.Root dislocation before the crown not only protects the roots of the adjacent tooth,but also reduces the risk of maxillary sinus lining damage or perforation during operative procedures,improves the efficiency of the operation,and reduces surgical trauma,which conforms to the concept of minimally invasive surgery and provides a new idea and experience for the clinical extraction of such maxillary impacted third molars.
