In this study, a new methodology for designing and creating a custom-made template for maxillofacial surgery has been developed. The custom-made template can be used both for cutting and repositioning of the mandible arches for executing a BSSO (bilateral sagittal split osteotomy) treatment. The idea was developed in order to give the possibility of using a custom-made template with standard plates, thus reducing long times, high costs and low availability of custom-made plates; this represents the proof of novelty of the proposed template, based on a well-established methodology. The methodology was completely developed in the CAD virtual environment and, after the surgeons' assessment, an in-vitro experiment by a maxillofacial surgeon was performed in order to check the usability and the versatility of the system, thanks to the use of additive manufacturing technologies. When computer-aided technologies are used for orthognathic surgery, there are significant time and cost savings that can be realised, as well as improved performance. The cost of the whole operation is lower than the standard one, thanks to the use of standard plates. To carry out the procedures, the proposed methodology allows for inexpensive physical mock-ups that enable the BSSO procedure to be performed.
在本研究中，已开发出一种用于设计和创建颌面外科定制模板的新方法。该定制模板可用于下颌骨弓的切割和重新定位，以实施双侧矢状劈开截骨术（BSSO）治疗。提出该想法是为了实现使用带有标准钢板的定制模板的可能性，从而减少定制钢板的长时间制作、高成本和低可用性；基于成熟的方法，这体现了所提出模板的新颖性。该方法完全在计算机辅助设计（CAD）虚拟环境中开发，在外科医生评估之后，一名颌面外科医生进行了体外实验，以检验该系统的可用性和通用性，这得益于增材制造技术的应用。当计算机辅助技术用于正颌外科手术时，可以显著节省时间和成本，并提高性能。由于使用了标准钢板，整个手术的成本低于标准手术。为了实施这些手术步骤，所提出的方法允许制作廉价的实体模型，从而能够进行双侧矢状劈开截骨术。
