Surgical removal of intra-bony calcific benign lesions is technically challenging regarding its accessibility, proximity to vital structures, and deteriorating effect on the remaining bony structures.
Computer-guided buccal cortical plate separation was performed for ten patients using patient-specific osteotomy locating guides and pre-bent plates. The guide was designed to outline the osteotomy, the buccal cortical plate was separated, the lesion was removed, and finally, the pre-bent plates were used to fix the separated cortex.
Surgical procedures were uneventful for all patients, operation time was 39.5 ± 13.01 min, postoperative pain decreased within the follow-up time intervals, and there was a statistical significant difference between the time intervals (P value < 0.001). Edema and trismus were acceptable. One case showed nerve affection which resolved after 4 weeks.
Computer-guided buccal cortical plate separation for removal of intra-bony calcified benign lesions provides a promising approach, especially for inexperienced surgeons.

手术切除骨内钙化性良性病变在可达性、与重要结构的接近程度以及对剩余骨结构的破坏作用方面存在技术挑战。
使用患者特异性截骨定位导板和预弯板对10例患者进行计算机引导下的颊侧皮质骨分离。该导板旨在勾勒出截骨轮廓，分离颊侧皮质骨，切除病变，最后使用预弯板固定分离的皮质骨。
所有患者手术过程均顺利，手术时间为39.5±13.01分钟，术后疼痛在随访时间间隔内减轻，各时间间隔之间存在统计学显著差异（P值<0.001）。水肿和牙关紧闭情况可接受。1例出现神经损伤，4周后恢复。
计算机引导下颊侧皮质骨分离用于切除骨内钙化性良性病变提供了一种有前景的方法，尤其对于经验不足的外科医生。
