OBJECTIVES
Computer-assisted navigation has been established as a valuable tool in oral and craniomaxillofacial surgery. However, the steep learning curve associated with mandibular navigation surgery has hindered its widespread adoption. This study introduces a non-invasive, convenient, and accurate navigation method for mandibular surgery and evaluates its clinical effectiveness.
METHODS
A modified patient-specific dynamic reference frame (PS-DRF) was designed and fabricated based on the patient's lower jaw dental cast, integrating navigation technology with 3D printing. During surgery, the PS-DRF was securely affixed to the lower dentition, enabling automatic pair-point registration through fiducial localization via a navigation probe. The surgical procedure was conducted under real-time navigation guidance.
RESULTS
Preoperative registration and intraoperative navigation were successfully achieved in this case. The navigation-guided mandibular surgery was completed without complications. Postoperative superimposition of the simulated virtual model and the actual surgical outcome demonstrated high accuracy, with a deviation of less than 2 mm.
CONCLUSION
The PS-DRF system offers a convenient, effective, and adaptable approach by integrating navigation technology with 3D printing. This method has the potential to simplify navigation-assisted mandibular surgery and facilitate the broader clinical implementation of computer-assisted navigation in maxillofacial procedures.
目的
计算机辅助导航已成为口腔和颅颌面外科手术中的一项重要工具。然而，下颌骨导航手术相关的陡峭学习曲线阻碍了其广泛应用。本研究介绍一种用于下颌骨手术的无创、便捷且准确的导航方法，并评估其临床效果。
方法
基于患者下颌牙模设计并制作改良的个体化动态参考框架（PS-DRF），将导航技术与3D打印相结合。手术过程中，PS-DRF牢固地固定在下颌牙列上，通过导航探针进行基准定位实现自动点对点配准。手术操作在实时导航引导下进行。
结果
本病例成功实现术前配准和术中导航。导航引导下的下颌骨手术顺利完成，无并发症发生。术后模拟虚拟模型与实际手术结果的叠加显示出高精度，偏差小于2毫米。
结论
PS-DRF系统通过将导航技术与3D打印相结合，提供了一种便捷、有效且适应性强的方法。该方法有可能简化导航辅助下颌骨手术，并促进计算机辅助导航在颌面手术中更广泛的临床应用。
