We obtained successful functional and esthetic results by grafting of iliac marrow-cancellous bone in 2 cases of alveolar-palatal cleft patients. Bone graft of alveolar-palatal clefts provide bony support to adjacent teeth of cleft area, prevented from relapse of orthodontic arch expansion, closure of oroantral fistula and improvement of speech problem. 1. In one case, extraction of upper right central incisor that was little bone support, alignment of rotated teeth and expansion of collapsed arch segment were done with pre-ortodontic treatment. The other case, Bone grafting was done after removal of prosthesis with no preorthodontic treatment. 2. After mucoperiosteal incision in cleft area. The mucosal flap of labial area, palate and nose were separation and the raised nasal mucosa was sutured for closure of oroantral fistula. Then, the iliac marrow-cancellous bones were grafted to cleft site. 3. After 6 months of operation, we had seen the new bone deposition to cleft site in dental radiography and prosthetic treatments of missing teeth were done.
