Summary
This study presents a digital system for treating unilateral mandibular hyperplasia (UMH), improving facial symmetry and bite function. The personalized approach ensures precise, safe, and effective surgical outcomes for UMH patients.
Area of Science:
- Oral and Maxillofacial Surgery
- Digital Dentistry
- Surgical Planning
Background:
- Unilateral mandibular hyperplasia (UMH) causes facial asymmetry and bite issues.
- Current diagnostic and treatment guidelines for UMH are lacking.
- Digital technology offers potential for improved UMH management.
Purpose of the Study:
- To establish a digital technology-supported personalized surgical system for UMH.
- To evaluate the efficacy of this system in restoring facial aesthetics and function.
- To introduce novel surgical techniques and personalized treatment protocols for UMH.
Main Methods:
- Retrospective analysis of 8 adult UMH patients.
- Preoperative virtual surgical planning (VSP) with 3D-printed guides and splints.
- Modified intraoral IVRO and SSRO techniques.
- Personalized treatment protocols based on condyle activity (condylectomy, orthognathic surgery, contouring).
Main Results:
- Stable occlusion and restored facial symmetry in all patients.
- No recurrence observed postoperatively.
- Successful application of digital technology for precise surgical execution.
Conclusions:
- A digital technology-supported personalized surgical system effectively treats UMH.
- The system enables precise, safe, and functional restoration of the face.
- This approach offers a standardized yet individualized solution for UMH.
