摘要： 由于上颌第一磨牙MB2遗漏导致根尖囊肿,本病例采用显微根管再治疗、根尖切除倒充填、囊肿摘除、骨再生术及冠修复等方法对患牙进行综合治疗。通过临床检查和锥束计算机断层扫描(cone-beam computed tomography,CBCT)观察,患牙临床症状消失,CBCT显示骨缺损区范围减小,密度增加。经多学科联合治疗成功保存了上颌第一磨牙的功能,消除了根尖囊肿,促进了骨缺损的再生修复。

Abstract: Periapical cyst was caused by missing MB2 of the maxillary first molar. This case underwent comprehensive treatment of the affected tooth using methods such as micro root canal retreatment, apical resection and retrograde filling, cyst removal, bone regeneration surgery, and crown restoration. Through clinical examination and CBCT observation, the clinical symptoms of the affected tooth disappeared, and CBCT showed a decrease of bone defect areas and an increase of density. After multidisciplinary joint treatment, the function of the maxillary first molar was successfully preserved, and periapical cysts were eliminated, promoting the regeneration and repair of bone defects.

Key words: MB2 omission, periapical cyst, multidisciplinary therapy
