Computer-aided design and manufacturing (CAD/CAM) produced alloplastic implants effectively correct facial contour irregularities after jaw surgery. This technique offers a safe and satisfying solution for patients seeking aesthetic refinement following orthognathic procedures.
Area of Science:
- Oral and Maxillofacial Surgery
- Plastic Surgery
- Biomedical Engineering
Background:
- Le Fort I maxillary and sagittal split mandibular osteotomies correct dentofacial deformities.
- Large skeletal movements can lead to facial contour irregularities and imbalances.
Purpose of the Study:
- To evaluate the effectiveness of CAD/CAM alloplastic implants in correcting contour irregularities after orthognathic surgery.
- To assess patient satisfaction and surgical outcomes.
Main Methods:
- 3D CT scans analyzed for patients with post-orthognathic surgery aesthetic concerns.
- Custom alloplastic implants designed using CAD/CAM technology.
- Implants placed via intraoral and submental incisions, secured with titanium screws.
Main Results:
- 21 patients received CAD/CAM alloplastic implants.
- High patient satisfaction reported with the aesthetic results.
- One patient required implant removal due to infection; others had minimal morbidity.
Conclusions:
- CAD/CAM alloplastic implants are effective for refining facial appearance after orthognathic surgery.
- The surgical placement of these custom implants demonstrates minimal morbidity and high patient satisfaction.
