在颅颌面外科领域，正颌外科是致力于纠正因骨性错牙合引起的牙颌面畸形的一个特殊领域。一般来说，在这种情况下，需要一种跨学科的正畸和外科治疗方法。在对牙弓进行初步矫正后，颌骨的骨骼差异可以通过不同的手术策略和程序来纠正，以实现正确的咬合关系，以及个性化治疗理念下的面部平衡与和谐。为了转移术前的手术计划和重新定位具有最佳咬合关系的活动牙弓，通常使用外科夹板。为此，已经描述了使用一种或多种夹板的不同策略。传统上，这些夹板是由牙科技术人员根据患者特定的牙型制作的；然而，计算机辅助技术在术前规划及其随后的手术转移方面变得越来越重要。：在一项对10名患者进行的初步研究中，每个患者都制作了两个最终的咬合夹板，并就其临床可用性进行了比较。一种夹板是由牙科技师根据术前手术计划以传统方式制作的。在对患者的牙齿模型进行CBCT扫描后，根据所需的最终咬合情况，工程师和外科医生实际上共同设计了第二个夹板。为此，使用了定制的软件平台RapidSplint®。在将数据集后处理并转换为.stl文件后，通过PolyJet程序使用光聚合来制造夹板。在手术中，两种夹板都是在牙弓松动后插入的，然后根据咬合适合性比较它们的临床可用性。使用上述工作流程，在这项初步研究中，可以为所有患者设计和制造虚拟夹板。临床上可以使用10个虚拟夹板中的8个来达到和维持正颌外科手术后的最终咬合。在两个病例中，虚拟夹板因咬合配合不足而不能使用，甚至有两个传统夹板不能在临床上使用。在两种夹板都有的5名患者中，他们的咬合适合性被评估为等效，在一例中，虚拟夹板显示出比传统夹板更好的咬合适合性。在一个没有传统夹板的情况下，虚拟夹板被证明有助于实现最终的咬合。在这项初步研究中，证明了临床上可用的正颌外科夹板可以通过计算机辅助技术生产出来。虚拟夹板设计是通过RapidSplint®实现的，这是一个内部软件平台，未来可能有助于缩短正颌外科夹板生产的术前工作流程。
Within the domain of craniomaxillofacial surgery, orthognathic surgery is a special field dedicated to the correction of dentofacial anomalies resulting from skeletal malocclusion. Generally, in such cases, an interdisciplinary orthodontic and surgical treatment approach is required. After initial orthodontic alignment of the dental arches, skeletal discrepancies of the jaws can be corrected by distinct surgical strategies and procedures in order to achieve correct occlusal relations, as well as facial balance and harmony within individualized treatment concepts. To transfer the preoperative surgical planning and reposition the mobilized dental arches with optimal occlusal relations, surgical splints are typically used. For this purpose, different strategies have been described which use one or more splints. Traditionally, these splints are manufactured by a dental technician based on patient-specific dental casts; however, computer-assisted technologies have gained increasing importance with respect to preoperative planning and its subsequent surgical transfer. : In a pilot study of 10 patients undergoing orthognathic corrections by a one-splint strategy, two final occlusal splints were produced for each patient and compared with respect to their clinical usability. One splint was manufactured in the traditional way by a dental technician according to the preoperative surgical planning. After performing a CBCT scan of the patient’s dental casts, a second splint was designed virtually by an engineer and surgeon working together, according to the desired final occlusion. For this purpose, RapidSplint®, a custom-made software platform, was used. After post-processing and conversion of the datasets into .stl files, the splints were fabricated by the PolyJet procedure using photo polymerization. During surgery, both splints were inserted after mobilization of the dental arches then compared with respect to their clinical usability according to the occlusal fitting. Using the workflow described above, virtual splints could be designed and manufactured for all patients in this pilot study. Eight of 10 virtual splints could be used clinically to achieve and maintain final occlusion after orthognathic surgery. In two cases virtual splints were not usable due to insufficient occlusal fitting, and even two of the traditional splints were not clinically usable. In five patients where both types of splints were available, their occlusal fitting was assessed as being equivalent, and in one case the virtual splint showed even better occlusal fitting than the traditional splint. In one case where no traditional splint was available, the virtual splint proved to be helpful in achieving the final occlusion. In this pilot study it was demonstrated that clinically usable splints for orthognathic surgery can be produced by computer-assisted technology. Virtual splint design was realized by RapidSplint®, an in-house software platform which might contribute in future to shorten preoperative workflows for the production of orthognathic surgical splints.
