Functional reconstruction of the mandible: a modified titanium mesh system

Area of Science:

• Oral and Maxillofacial Surgery
• Biomaterials Engineering
• Reconstructive Surgery

Background:

• Mandibular defects require advanced reconstructive techniques.
• Current methods may face challenges in achieving anatomical accuracy and functional restoration.
• The need for predictable and implant-compatible reconstruction is critical.

Purpose of the Study:

• To describe a novel method for mandibular reconstruction.
• To utilize a patient-specific titanium mesh with autogenous cancellous bone.
• To achieve symmetric, functional, and implant-ready mandibular restoration.

Main Methods:

• Preoperative design of a titanium mesh based on a mandibular duplicate.
• Modification of the duplicate to simulate the edentulous segment.
• Fabrication of a locating splint for intraoperative mesh positioning.
• Articulation with a maxillary dental cast for accurate placement.

Main Results:

• The described method allows for precise anatomical reconstruction of the mandible.
• The technique facilitates the integration of dental implants for future rehabilitation.
• Achieved reconstructions are both symmetric and highly functional.

Conclusions:

• This patient-specific titanium mesh technique offers a reliable approach for mandibular reconstruction.
• The method enhances functional outcomes and aesthetic symmetry.
• It provides a solid foundation for prosthetic rehabilitation with dental implants.
