Summary
Mixed reality technology offers an intuitive and flexible approach to setting surgical occlusion in orthognathic surgery. This virtual method provides comparable accuracy to traditional physical models, enhancing digital planning workflows.
Area of Science:
- Oral and Maxillofacial Surgery
- Digital Dentistry
- Surgical Planning Technologies
Background:
- Orthognathic surgery requires precise occlusal alignment for optimal outcomes.
- Traditional planning relies on manual alignment of physical dental models, the established gold standard.
- Virtual methods are emerging alternatives for occlusion setting.
Purpose of the Study:
- To evaluate the efficacy of mixed reality (MR) technology for surgical occlusion setting in orthognathic surgery.
- To compare MR technology against traditional physical model alignment and an established virtual method.
- To determine if MR improves accuracy and efficiency in orthognathic surgery planning.
Main Methods:
- An experimental study involving 30 orthognathic surgery cases.
- Comparison of three occlusion setting methods: mixed reality, traditional physical models, and established virtual occlusion (IPS Case Designer).
Main Results:
- Mixed reality-derived occlusions showed comparable maxillary movement and occlusal relationships to the conventional method.
- Virtual methods, including MR, tended towards more anterior maxillary positioning and fewer occlusal contacts.
- Virtual occlusion demonstrated clinical applicability with an average of 11 bilaterally symmetrical occlusal contacts.
Conclusions:
- Mixed reality provides an intuitive and flexible virtual occlusion setting experience.
- It eliminates the need for costly physical models and complex automatic calculations.
- This technology supports a timely, cost-effective, and fully digital workflow for orthognathic surgery planning.
