Introduction: The mandibular ameloblastoma is a benign odontogenic tumor that develops from the remaining components of the enamel organ. It is a slow growing, locally aggressive tumor capable of causing facial deformity. It has a high recurrence rate due to its capacity to infiltrate trabecular bone. The literature presents options to treatment of ameloblastoma with conservative or radical approaches.

Aim: The aim is to present a case report of ameloblastoma that was performed a mandibular resection associated to autogenous intraoral graft followed by osseointegrated implants rehabilitation.

Case report: A 24 years old female patient of authors clinic presented in a panoramic radiograph and a CT scan similar images to multicystic ameloblastoma, involving teeth with buccal cortical swelling. Under general anesthesia were performed the resection of lesion and teeth extraction followed by autogenous bone reconstruction. Only intraoral bone blocks from retromolar region were fixed with titanium micro screws in conjunction with rich platelet plasma (RPP). The results of histopathologic study were multicystic follicular ameloblastoma. A control postoperative CT scan was performed six months after surgery, confirming consolidation of the graft. Re-entry was performed at 6 months after first surgery to retrieval of titanium micro screws and placement of osseointegrated implants. The patient was followed up in a period of 5 years after prosthetic rehabilitation and there is no evidence of recurrence.

Conclusion: The treatment performed in this case confirmed that a conservative approach is a good option for treatment of follicular ameloblastoma.
