Abstract

This study aimed to evaluate the efficiency and accuracy of autotransplantation of complex impacted teeth by CAD/CAM digital navigation technology. An 11-year-old girl with complex impacted second premolars bilaterally in the maxilla was selected. CAD/CAM digital dynamic navigation was utilized to ensure the precision and success of the procedure. A comprehensive accuracy analysis was conducted to compare the preoperative digital simulation design with the postoperative positions of the transplanted teeth. The transplanted teeth functioned well after 1 year of follow-up. Postoperative CBCT clinical data, combined with Mimics 21.0 and 3-Matic 13.0 software, revealed that the depth and buccolingual deviations of the bilateral autotransplantation were within 2.0 millimeters, with a mesiodistal deviation of approximately 1.0 millimeter. This case demonstrates the high efficiency, precision, and stabilization provided by digital navigation technology, highlighting its potential as a viable option for the treatment of complex impacted teeth.

基于CAD/CAM数字导航的复杂埋伏牙精密自体移植多学科联合治疗。

本研究旨在评价CAD/CAM数字导航技术在复杂阻生牙自体移植中的效率和准确性。我们选择了一名11岁的女孩，在上颌骨两侧有复杂的第二前磨牙阻生。采用CAD/CAM数字动态导航，保证了加工的精度和成功率。对术前数字模拟设计与术后移植牙位置进行综合精度分析。术后随访1年，移植牙功能良好。术后CBCT临床资料结合Mimics 21.0和3-Matic 13.0软件显示，双侧自体移植深度和颊舌偏差在2.0 mm以内，中远端偏差约1.0 mm。本病例展示了数字导航技术的高效率、精度和稳定性，突出了其作为治疗复杂阻生牙的可行选择的潜力。
