摘要： 目的:探讨基于锥形束CT(cone beam computed tomography,CBCT)和计算机辅助设计/制造(computer aided design/computer aided manufacturing,CAD/CAM)技术设计的数字化定位导板在完全骨埋伏牙拔除术中的临床应用效果。方法:选取36例2020年1~12月就诊于新疆医科大学第一附属医院口腔颌面外科门诊,应用数字化定位导板拔除完全骨埋伏牙的患者为研究对象,其中男性15例,女性21例,共36颗完全骨埋伏牙,分别记录定位埋伏牙时间、手术时间、开窗面积、术中出血量、术中及术后并发症等情况。结果:所有患者均顺利完成手术,应用数字化定位导板平均定位埋伏牙时间为(1.85±0.64) min,平均手术时间为(24.15±2.88) min,术中平均开窗面积为(63.81±8.69) mm2,平均出血量为(8.87±1.89) mL。均未出现定位偏差、邻牙损伤等术中并发症及张口受限及神经、血管损伤的情况。其中1例患者拔除术后出现与上颌窦交通(鼓腮漏气)的情况,1例患者术后3 d出现拔牙创口感染的情况。结论:利用数字化定位导板在微创拔除完全骨埋伏牙中获得较好的临床效果,可快速精准定位埋伏牙,减少手术创伤,缩短手术时间,且有效减少额外骨组织、邻牙牙根及邻近神经血管的损伤,减轻患者术后反应,且符合"微创、精确"的理念,值得临床推广应用。

Abstract: Objective: To explore and evaluate the clinical effect of digital positioning guide template in extraction of complete bone impacted teeth based on CBCT and CAD/CAM technology. Methods: A total of 36 patients treated in the Oral and Maxillofacial Surgery Clinic of the First Affiliated Hospital of Xinjiang Medical University from January 2020 to December 2020 were selected, who used digital positioning guide template to extract complete bone impacted teeth, including 15 males and 21 females. The teeth positioning time, operation time, fenestration area, operative blood loss, operative and postoperative complications were recorded. Results: All patients successfully completed the operation. The average time to position the complete bone impacted teeth using the digital positioning guide plate was (1.85±0.64) min, the average operation time was (24.15±2.88) min, the average operative fenestration area was (63.81±8.69) mm2, and the average operative blood loss was (8.87±1.89) mL. There were no operative complications, such as positioning deviation, adjacent tooth injury, restricted mouth opening, and nerve and blood vessel damage. One patients had air leak of maxillary sinus after the extraction, and one patient had infection of the extraction wound 5 days after the operation. Conclusion: The use of digital positioning guide template can achieve good clinical results in minimally invasive extraction of complete bone impacted teeth.
