This study details a novel silicone maxillofacial prosthesis for total mandibular defects. The unique design offers stable retention using the auricles and remaining teeth, avoiding implants and adhesives.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Biomedical Engineering
  • Prosthodontics

Background:

  • Reconstruction of total mandibular defects presents significant challenges.
  • Limited information exists on prostheses for complete mandibular loss.
  • Existing methods often rely on invasive extraoral implants or adhesives.

Observation:

  • A 54-year-old female patient presented with total loss of the mandible and surrounding facial soft tissue.
  • The defect resulted from surgical failure in previous mandibular reconstruction.
  • Conventional retention methods were unsuitable for this extensive defect.

Findings:

  • A large, custom-designed silicone maxillofacial prosthesis was fabricated for the patient.
  • The prosthesis achieved adequate retention through bilateral auricle support and remaining upper anterior teeth.

  • This innovative retention method eliminated the need for extraoral implants and adhesives.

    • Implications:

    • This fabrication technique offers a viable solution for extensive mandibular defects.
    • The implant- and adhesive-free retention method enhances patient comfort and reduces complications.
    • Successful rehabilitation demonstrates the potential of custom maxillofacial prostheses in complex cases.
