To present a minimally invasive approach to expose palatally displaced canines (PDCs) using a surgical guide.
Surgical guides for palatal canine exposure are fabricated with CAD/CAM technology. With adequate software, it is possible to match the STL files of the dental arch with the DICOM images of the maxilla. On the STL 3D model file, the operator can localize and determine the exact position of the impacted canine. In turn, this allows the identification of the ideal location of the window. A software application facilitates the design of the surgical guide, which is printed using a 3D printer.
Exposure of PDCs can be achieved satisfactorily using surgical guides.
The use of computer-guided surgical exposure of PDCs allows both the reduction of surgical time and surgical invasiveness, minimizing patients' postoperative discomfort. Controlled clinical trials are necessary to evaluate more fully any advantages of this minimally invasive technique.
介绍一种使用手术导板微创暴露腭向错位埋伏尖牙（PDC）的方法。
采用 CAD/CAM 技术制作腭部犬齿暴露手术导板。借助合适的软件，可以将牙弓的 STL 文件与上颌骨的 DICOM 图像相匹配。在 STL 3D 模型文件上，术者可以定位并确定埋伏犬牙的确切位置。反过来，这也可以确定开窗的理想位置。软件应用程序可以方便地设计手术导板，然后使用 3D 打印机进行打印。
使用手术导板可以满意地暴露 PDC。
使用计算机引导的 PDC 手术暴露可以减少手术时间和手术侵袭性，最大限度地减少患者术后不适。有必要进行对照临床试验，以更全面地评估这种微创技术的任何优势。
