Summary
Virtual surgical planning using 3D CT enhances orthognathic surgery outcomes. This technology provides predictable and reliable results for improved facial aesthetics and jaw alignment.
Area of Science:
- Oral and Maxillofacial Surgery
- Plastic Surgery
- Medical Imaging
Background:
- Orthognathic surgery aims to harmonize jaw relationships and improve facial aesthetics.
- Evaluating virtual surgical planning (VSP) is crucial for its routine clinical adoption.
Purpose of the Study:
- To assess soft tissue changes after orthognathic surgery using 3D imaging and VSP software.
- To quantify the accuracy of VSP in orthognathic procedures.
Main Methods:
- Prospective observational study with 12 patients undergoing orthognathic surgery.
- 3D facial skeleton models created from CT and dental scans.
- Virtual surgical planning and CAD-CAM splint fabrication for guided surgery.
Main Results:
- Mean soft tissue discrepancy of 0.92 (SD 0.3) observed post-superimposition.
- Descriptive analysis of a single patient group without statistical testing.
Conclusions:
- 3D CT-based virtual surgical planning is a dependable method for achieving predictable outcomes in orthognathic surgery.
