Summary
Patient-specific angle implants enhance jawline definition in orthognathic surgery. This study shows these implants safely improve jaw angle aesthetics, meeting ideal parameters for both males and females.
Area of Science:
- Plastic Surgery
- Oral and Maxillofacial Surgery
- Biomedical Engineering
Background:
- Global demand for jawline augmentation is rising.
- Orthognathic surgery presents challenges in modifying ramus height for jawline definition.
- Computer-assisted techniques offer new solutions for jawline management.
Purpose of the Study:
- To evaluate jawline improvement using patient-specific angle implants in orthognathic surgery patients.
- To assess the aesthetic refinement of the jawline, including soft tissue changes.
- To compare postoperative results with ideal jaw angle parameters.
Main Methods:
- Utilized patient-specific angle implants in 18 patients undergoing standard osteotomies.
- Employed 3D-photographs (VECTRA H2 Imaging System) for preoperative and postoperative facial analysis.
- Conducted both qualitative and quantitative analyses of jawline parameters.
Main Results:
- Achieved a mean volumetric angle expansion of 4.6 mm (males: 4.71 mm, females: 4.48 mm).
- Demonstrated that postoperative jaw angle parameters aligned with established ideal facial aesthetics.
- Confirmed concordance between quantitative measurements and aesthetic goals.
Conclusions:
- Patient-specific titanium angle implants are a safe and effective method for jawline enhancement.
- These implants offer a promising solution for aesthetic refinement in orthognathic surgery.
- The technique successfully addresses limitations of traditional mandibular osteotomies for jawline definition.
