Juvenile ossifying fibroma is a benign fibro-osseous lesion with an unusual presentation that predominantly affects individuals in the first decade of life. The aggressiveness added to the high rates of recurrence causes real diagnostic and therapeutic challenges for the dental surgeon and makes post-operative follow-up over the years indispensable. We present the case of a 21-year-old girl with a rapid onset and abrupt increase in volume in the left maxilla. After clinical, radiographic and histopathological exams, the diagnosis of trabecular juvenile ossifying fibroma was obtained. The lesion was surgically removed and the patient was rehabilitated with a removable partial prosthesis, due to the involvement of some teeth during surgical access. The present clinical case demonstrates that the adequate treatment must consist of complete surgical excision, early functional and aesthetic prosthetic rehabilitation and long-term preservation.
