Rehabilitating Wide Maxillary Defect with Distraction Osteogenesis and Khoury Technique: Case Report

Abstract

Maxillary and mandibular bone defects can result from injury, congenital defect or accident, or as a consequence of surgical procedures when treating pathology or defects affecting jaw bones. And with conventional bone grafting techniques, it is not possible to close these kind of defects. Distraction osteogenesis has become a very popular technique, as the ability to reconstruct combined deficiencies in bone and soft tissue makes this process unique and invaluable to all types of reconstructive surgeons. The aim of this article is to present the case of a 52-year-old female patient, who, in 2016, was operated at another center for tumour resection. After these, patient referred to our center and we treated the wide anterior maxillary bone and soft tissue defect by using bilateral alveolar cleft distractor. After narrowing the wide defect with distraction osteogenesis, khoury technique was used for rehabilitating the small defect. As a result, using cleft distractor is an effective method for rehabilitation
