目的：介绍和评价一种改良的“蜡咬牙夹板”在颅颌面外科手术导航中的应用。材料和方法：制作一种2层蜡咬合夹板，每个夹板上加8个牙胶标记，用于基于标记的对点配准。为了评价其准确性，对10个人工颅骨进行了咬合登记。随后，使用标准化的锥束计算机断层扫描方案扫描所有的头骨，并使用2层蜡咬牙夹板就位。使用iPlan CMF软件3.0版(BrainLab AG，Feldkirchen，德国)使用8个牙胶标记结合到蜡咬合牙夹板中进行基于刚性标记的自动配对点配准。结果：每个蜡咬合牙夹板的平均配准误差为0.78~1.01 mm。基于蜡咬牙夹板的整体平均注册误差为0.89+/-0.08 mm。6个解剖标志的平均配准误差为1.23~2.3 mm。总的平均配准误差为1.68+/-0.28 mm。结论：本研究结果显示蜡咬合牙夹板作为颅颌面外科手术导航的一种替代刚性配准方法的潜力。此外，从临床角度来看，该方法准确、用户友好、廉价且不耗时。(C)2015年美国口腔颌面外科医生协会
Purpose: The purpose of the present study was to introduce and evaluate the use of a modified "waxbite dental splint" for surgical navigation in craniomaxillofacial surgery.Materials and Methods: A 2-layer wax bite dental splint was fabricated with an anterior extension, and 8 gutta percha markers were incorporated in each splint for marker-based pair-point registration. To evaluate the accuracy, the occlusal registration of the wax bite dental splint was performed on 10 artificial skulls. Consecutively, all the skulls were scanned using a standardized cone-beam computed tomography scanning protocol with the 2-layer wax bite dental splint in place. Automatic rigid marker-based pair-point registration was performed using the iPlan CMF software, version 3.0 (Brainlab AG, Feldkirchen, Germany) using 8 gutta percha markers incorporated into the wax bite dental splint. Additionally, the registration accuracy of 6 anatomic skeletal landmarks was measured on each skull.Results: The mean registration error for each wax bite dental splint ranged from 0.78 to 1.01 mm. The overall mean registration error for the wax-bite dental splint-based registration was 0.89 +/- 0.08 mm. The mean registration error for the 6 anatomic landmarks ranged from 1.23 to 2.3 mm. The overall mean registration error was 1.68 +/- 0.28 mm.Conclusion: The results of the present study show the potential for a wax-bite dental splint as an alternative rigid registration method for surgical navigation in craniomaxillofacial surgery. Moreover, from a clinical viewpoint, the method is accurate, user-friendly, inexpensive, and not time-consuming. (C) 2015 American Association of Oral and Maxillofacial Surgeons
