Summary
Virtual occlusion is as accurate as conventional methods in orthognathic surgery. This digital approach eliminates the need for physical dental models, streamlining clinical practice.
Area of Science:
- Dentistry
- Orthodontics
- Digital Imaging
Background:
- Conventional occlusions rely on physical dental models.
- Virtual occlusion offers a digital alternative.
- Assessing the accuracy of virtual occlusion is crucial for clinical adoption.
Purpose of the Study:
- To compare the accuracy of virtually created occlusion with conventionally created occlusion.
- To evaluate the clinical applicability of a virtual occlusion tool.
Main Methods:
- Retrospective study of 17 orthognathic patients.
- Digitization of plaster cast models.
- Conventional and virtual occlusion creation by two observers to assess variability.
Main Results:
- No statistically significant differences were found between conventional and virtual occlusion groups.
- The difference between virtual and conventional occlusion was within acceptable limits (0.20mm larger than intra-observer variability).
Conclusions:
- Virtual occlusion tools are accurate and can be used in daily clinical practice.
- Physical dental models may become redundant with the adoption of virtual occlusion technology.
