本研究的目的是评估一个个性化的正颌外科手术导向器（POSG）系统的双颌手术，而不使用手术夹板。10例牙颌面畸形患者入组。手术计划采用计算机辅助手术模拟方法。POSG系统设计用于上颌和下颌手术。每个都由切割导向器和三维（3D）打印定制钛板组成，用于引导截骨术和重新定位骨段，而无需使用手术夹板。最后，通过比较计划结局与术后结局完成结局评价。所有手术均使用POSG系统成功完成。最大均方根偏差上颌牙弓为0.74 mm和1.93°，下颌牙弓为1.10 mm和2.82°，下颌体为0.83 mm和2.59°，近端为0.98 mm和2.45°。研究结果表明，我们的POSG系统能够准确和有效地传递手术计划，而无需使用手术夹板。一个显著的优点是骨段的重新定位独立于下颌自转，从而消除了与外科夹板相关的潜在问题。
The purpose of this study was to evaluate a personalized orthognathic surgical guide (POSG) system for bimaxillary surgery without the use of surgical splint. Ten patients with dentofacial deformities were enrolled. Surgeries were planned with the computer-aided surgical simulation method. The POSG system was designed for both maxillary and mandibular surgery. Each consisted of cutting guides and three-dimensionally (3D) printed custom titanium plates to guide the osteotomy and repositioning the bony segments without the use of the surgical splints. Finally, the outcome evaluation was completed by comparing planned outcomes with postoperative outcomes. All operations were successfully completed using the POSG system. The largest root-mean-square deviations were 0.74 mm and 1.93° for the maxillary dental arch, 1.10 mm and 2.82° for the mandibular arch, 0.83 mm and 2.59° for the mandibular body, and 0.98 mm and 2.45° for the proximal segments. The results of the study indicated that our POSG system is capable of accurately and effectively transferring the surgical plan without the use of surgical splint. A significant advantage is that the repositioning of the bony segments is independent to the mandibular autorotation, thus eliminates the potential problems associated with the surgical splint.
