Abstract
Aim: Describing the surgical/therapeutic and the prosthetic/functional approaches for the treatment and rehabilitation of a patient with an ameloblastoma in the posterior area of mandible. Materials and Methods: Enucleation of the lesion took place by surgical resection with bone margin extending to more than 1 cm beyond the lesion's macroscopic margins, without performing guided bone regeneration. A year after surgery, a panoramic radiograph (OPG) was performed and seven implants were inserted to rehabilitate the lower arch. The upper arch was rehabilitated with implant-prosthetic full-arch structure (flat-one-bridge) and immediate functional loading within 72 hours. Results and Conclusions: A 30 month follow-up shows good peri-implant tropism with bone margins continuity and osteointegration to the bone previously compromised by the lesion. The non-invasive treatment of lesions of maxillary bones is very useful to maintain the interarch occlusal relationship since it accelerates bone healing and optimizes the soft tissues morphology.

Summary
Ameloblastoma is a benign epithelial odontogenic tumour first described by Cusack in 1827 [1]. It presents 1% of all oral tumours and 18% of tumours of odontogenic origin with age peak at the 4th decade of life [2]. It affects primary the posterior mandible (75%) [3] with annual incidence per million of 1.96 among black males, 1.2 among black females, 0.18 among white males and 0.44 among white females [4]. The unilocular form of ameloblastoma is radiographically similar to a cystic lesion and rarely, as in our case, engulfing a tooth simulating a dentigerous cyst
