Secondary bone grafting with simultaneous auto-tooth transplantation to the alveolar cleft.

One of the most important purposes of secondary bone grafting of the alveolar cleft is to stabilize the maxillary alveolar arch with completion of the dental arch. We report a case of secondary bone grafting with simultaneous auto-tooth transplantation to the alveolar cleft, using particulate cancellous bone and marrow (PCBM) combined with platelet-rich plasma (PRP), which contains many growth factors. The patient was born with a bilateral cleft lip and left buccal-localized cleft alveolus. We performed bone grafting to the cleft using PCBM with PRP and transplantation of the supernumerary tooth under general anesthesia when the patient was aged 11 years, 10 months. The postoperative course was uneventful and without any complications. The orthodontic treatment was nearly complete 10 months after the operation. The transplanted tooth was stable, and a normal gingival contour was attained during the 2-year follow-up period. The case was successful in achieving a stable occlusal condition within a short period. We suggest secondary bone grafting with simultaneous auto-tooth transplantation as an option for alveolar cleft treatment.
