Myxofibroma of the maxilla. Reconstruction with iliac crest graftand dental implants after tumor resection

ABSTRACT

Odontogenic fibromyxomas are benign odontogenic tumors of mesenchymal origin of rare presentation in the oralcavity, which exhibit locally aggressive behavior and are prone to local recurrence. The controversy has mainlybeen on therapeutic management with recommendations varying, depending on the clinical cases, from simplecurettage of lesion to segmental bone resection. We present a case report describing the reconstruction of an os-seous defect in the maxilla and the restoration with dental implants in a 32 year old female patient after radicalsurgical excision due to an odontogenic fibromyxoma with locally aggressive behavior. The primary reconstructionof maxillary discontinuity defect was carried out by an immediate non-vascularized cortico-cancellous iliaccrest graft. Using a computer-guided system for the implant treatment-planning, three dental implants were secondaryplaced in the bone graft by means of flapless implant surgery. The patient was subsequently restored withan implant-supported fixed prosthesis that has remained in continuous function for a period of three years. Thesurgical, reconstructive and restorative treatment sequence and techniques are discussed (AU)
