Summary
This study presents a novel prosthetic solution for extensive midfacial defects. A combined removable silicone and acrylic prosthesis, secured by magnets and spectacles, effectively restored function and appearance.
Area of Science:
- Oral and Maxillofacial Surgery
- Prosthodontics
- Biomaterials Science
Background:
- Maxillofacial defects present significant rehabilitation challenges for prosthodontists.
- Material selection, retention methods, patient adaptation, and cost are key considerations.
Observation:
- A patient with a large midfacial defect involving the orbit, zygoma, and maxilla required complex reconstruction.
- The defect included both hard and soft tissue components.
Findings:
- A custom-fabricated, removable prosthesis was designed with separate silicone extraoral and acrylic intraoral components.
- Retention was achieved using cobalt samarium magnets, an occipital elastic loop, and spectacles.
- The prosthesis successfully restored facial esthetics, speech, articulation, lip support, mastication, and the anterior maxillary seal.
Implications:
- This prosthetic approach offers a viable solution for managing extensive maxillofacial defects.
- The combination of materials and retention mechanisms provides functional and esthetic rehabilitation.
- Further research into advanced retention systems and materials for maxillofacial prostheses is warranted.
