AMELOBLASTOMA RESECTION, MANDIBULAR RECONSTRUCTION WITH AUTOLOGOUS ILIAC CREST BONE GRAFT AND PROSTHETIC REHABILITATION:

A CLINICAL CASE REPORT.

Résumé

Ameloblastoma is a benign but locally invasive odontogenic tumor, representing about 1% of oral neoplasms, with an incidence of 0.5 cases per million per year. Despite its benign histology, it shows aggressive behavior and high recurrence rates when inadequately treated, requiring surgical resection with safety margins and proper reconstruction. A 16-year-old female presented with progressive swelling in the right mandibular body. Imaging revealed an extensive multifocal radiolucent lesion involving teeth 45–48, suggestive of ameloblastoma. Treatment consisted of partial mandibular resection with margins and immediate reconstruction using an autogenous iliac crest graft, whose biological properties and volume enabled mandibular continuity and supported future rehabilitation. After healing, the patient received osseointegrated implants and implant-supported prostheses, restoring function and aesthetics. Segmental resection with immediate autogenous iliac crest grafting is a safe and effective option for extensive ameloblastomas, promoting stability and compatibility for implant placement. Successful outcomes depend on meticulous planning and strict postoperative follow-up.
