Area of Science:

  • Plastic Surgery
  • Oral and Maxillofacial Surgery
  • Aesthetic Medicine

Background:

  • The mandible's shape significantly influences facial aesthetics and sexual dimorphism in the lower face.
  • Computer-aided design/computer-aided manufactured (CAD/CAM) alloplastic implants offer advanced solutions for correcting mandibular skeletal deficiencies and asymmetries.

Purpose of the Study:

  • To present the rationale, indications, techniques, and outcomes of a 15-year experience using CAD/CAM alloplastic implants for mandibular augmentation.
  • To evaluate the effectiveness of CAD/CAM implants in correcting mandibular deficiencies and asymmetries.

Main Methods:

  • A retrospective review of a prospectively maintained database was conducted.
  • The study included all patients who underwent aesthetic mandibular augmentation with CAD/CAM alloplastic implants performed by the senior author over 15 years.

Main Results:

  • 123 patients underwent mandibular augmentation with CAD/CAM alloplastic implants over 15 years; the majority were male (76.4%) with an average age of 31.
  • Complications included infection (2.4%), implant revision due to dissatisfaction (4.1%), and implant removal (2.4%).

Conclusions:

  • CAD/CAM alloplastic implants are an effective method for augmenting aesthetic deficiencies in mandibular contour.
  • The study demonstrates the successful application of CAD/CAM technology in improving facial aesthetics through mandibular augmentation.
