Mandibular reconstruction using a titanium mesh sheet processed by laser welding after segmental mandibulectomy for implant placement

Abstract

Segmental mandibulectomy is performed in cases of benign and malignant neoplasms of the mandible, and both functional and esthetic aspects must be taken into account during mandibular reconstruction when mandibular continuity has been lost. Titanium mesh may be used as one method of reconstruction following segmental mandibulectomy. Mandibular reconstruction with titanium mesh offers the advantage of simplicity, allowing completion of the operation in a short time, and has a wide range of applications. Postoperative morphology is also close to anatomical mandibular morphology, resulting in satisfactory esthetics. In addition, sufficient bone remains postoperatively for the use of dentures or implant prostheses. We used preoperative simulation with a craniofacial bone model and laser welding to process a flat mesh sheet to fit the individual mandibular morphology of the patient prior to surgery. After reconstruction, we performed occlusal reconstruction by inserting implants into the transplanted bone.
