A case of application of bone transport and bone graft using Auto-tooth bone for alveolar cleft repair

Introduction: Secondary autogenous cancellous bone grafting is a widely used method for the treatment of alveolar clefts and oronasal fistulae. However, failure of iliac bone grafting sometimes occurs due to inadequate covering with the surrounding soft tissue and marked scar formation, or large clefts. We report a case of application of the combination for alveolar cleft repair of Maxillary bone transport surgery and Auto-tooth bone graft system using autogenous extracted teeth developed in Korea.

Case: A female 9-years old patient suffering from unilateral cleft lip and palate (left-side) were treated with this method. We planned maxillary bone transport surgery using a virtual operation with SimPlant OMS to correct the maxillary midline and deviated nasal septum. After sagittal interdental right-side maxillary osteotomy between #11 and 12 is performed completely to the nasal floor, alveolar maxillary bone (#11, 21) was transported in the planned direction (left) using a Martin’s distractor and closed the alveolar cleft. At the end of the transporter activation period, soft tissue in the cleft was removed so called “Docking surgery” using an electric knife for close bone contact at the docking site. We performed teeth extraction; 2 supernumerary teeth and small Lt. lateral incisor for Auto-tooth bone materials. We performed bone transporter removal and simultaneously Auto-tooth bone grafting to the docking area.

Result: Maxillary bone transport allowed good distraction osteogenesis and soft tissue expansion. Auto-tooth bone grafting to the docking site allowed repair of bone defects of nasal floor and alveolar and better bone connection.
