Introduction:

Ameloblastoma is a benign tumor of odontogenic epithelium with a tendency to local recurrence if not removed appropriately. Reconstruction alternatives include the use of microvascularized free flaps, plates and customized titanium prostheses.

Objective:

Describe a case of mandibular replacement with a customized titanium prosthesis after ameloblastoma excision.

Case presentation:

A case is presented of a female 44-year-old patient who presented a radiographic finding during pulporadicular treatment of tooth 37. Facial physical examination found an increase in volume in the left genian region, and intraoral observation detected expansion of the corticals in the lower posterior arch of the same side. Panoramic radiography and computed axial tomography showed a multilocular radiolucid image resembling soap bubbles which extended from the mandibular body to the left condyle. A sample was taken for biopsy, which confirmed the diagnosis of follicular pattern ameloblastoma. Segmental mandibular surgery was performed by cervical approach with a safety margin and exarticulation. The portion removed was replaced with a customized titanium prosthesis. Post-operative control showed a good evolution.

Conclusions:

Surgery was the basic component of the treatment applied. Surgical resection was followed by reconstruction of the defect with a customized titanium prosthesis, a procedure of great novelty in our environment useful to restore function and esthetic appearance.
