The ossifying fibroma (OF) is an unfrequent fibro-osseous lesion that generally affects middle age woman, usually setting in the posterior area of the jaw. Clinically the patient can present a long-term asymptomatic swelling that generates teeth displacement as an early manifestation.

Radiographically it is characterized for being a radiolucid lesion in its first stages, then it evolves to a mixed lesion with variable radioopaque areas and ends as an extremely radioopaque lesion.

The treatment varies according to its size and it can vary from a conservative surgery to a block resection followed by reconstruction through a bone graft.

We present a five years controlled case of a big size OF in a 22-year-old male patient. The specific clinical and histological characteristics are described. It is presented, according to the lesion extension, a therapeutic conduct with a block resection of the affected jaw segment with the posterior reconstruction through a free microvascular fibula flap.

Four dental titanium osseointegrated implants were installed on the bone graft. The oral rehabilitation was made by an implant supported hybrid oral prosthesis associated to excellent, functional and aesthetic, results.
