Abstract
Objectives: Orthognathic surgery necessitates precise occlusal alignment during surgical planning, traditionally achieved through manual alignment of physical dental models as the recognized gold standard. This study aims to evaluate the efficacy of mixed reality technology in enhancing surgical occlusion setting compared to traditional physical alignment and an established virtual method, addressing the research question: Can mixed reality technology improve the accuracy and efficiency of occlusion setting in orthognathic surgery planning?
Materials & methods: This experimental study compared the surgical occlusion settings of 30 orthognathic cases using three methods: a new virtual method with mixed reality technology, the traditional gold standard of physical alignment, and an established virtual occlusion method using the IPS Case Designer (KLS Martin SE & Co. KG, Tuttlingen, Germany).
Results: Results indicated that surgical occlusions set with mixed reality technology were comparable to the conventional method in terms of maxillary movement and occlusal relationship. Differences observed were within the inter-observer variability of the gold standard. Both virtual methods tended to position the maxilla more anteriorly, resulting in fewer occlusal contacts. However, virtual occlusion demonstrated clinical applicability, achieving an average of 11 occlusal contacts with a bilaterally symmetrical distribution along the dental arch.
Conclusions: The mixed reality environment provides an intuitive and flexible experience for setting surgical occlusion, eliminating the need for costly 3D-printed physical models or the automatic calculations required by other virtual occlusion methods, thereby offering maximum freedom.
Clinical relevance: As a novel form of virtual occlusion, it presents a comprehensive tool that contributes to a timely and cost-effective full digital workflow of orthognathic surgery planning.
目的:正颌外科手术需要在手术规划期间进行精确的咬合对齐,传统上通过手动对齐实物牙科模型来实现,这是公认的黄金标准。本研究旨在评估混合现实技术在提高手术咬合对位方面的功效,与传统的物理对位和成熟的虚拟方法进行比较,从而解决研究问题:材料与方法:这项实验研究比较了使用三种方法对 30 个正颌病例进行手术咬合设置的情况:使用混合现实技术的新型虚拟方法、传统的物理对位黄金标准以及使用 IPS Case Designer(KLS Martin SE & Co. KG,德国图特林根)的成熟虚拟咬合方法:结果表明,在上颌移动和咬合关系方面,使用混合现实技术设置的手术咬合与传统方法相当。观察到的差异在金标准的观察者间变异范围内。两种虚拟方法都倾向于将上颌骨定位在更靠前的位置,从而减少咬合接触。不过,虚拟咬合显示出了临床适用性,平均实现了 11 次咬合接触,并沿牙弓呈双侧对称分布:混合现实环境为手术咬合的设置提供了直观灵活的体验,无需昂贵的 3D 打印物理模型或其他虚拟咬合方法所需的自动计算,从而提供了最大的自由度:作为虚拟咬合的一种新形式,它提供了一种全面的工具,有助于及时、经济高效地实现正颌外科手术规划的全数字化工作流程。
