Simultaneous implant installation with bone graft was performed in 15 cases. Four cases were cleft alveolus patients. 56 implants were placed immediately with block bone grafts. 2 csses were cranial bone grafts and the others were iliac bone grafts. Three of 56 implants were lost(94.6% survival rate). One of three was cleft alveolus case. The cleft alveolus patients with simultaneous implants installation showed functional and esthetic results without infraocclusion and positional changes. Bergland index was considered to be type I after 12 months later. Immediate implant installation with bone graft is one of choice of treatment in closing cleft alveolus hoping sitnultaneous implant installation could be related with function which might result in less resoiption of graft. Functional and esthetic results are satisfactoiy ; there was no infraocclusion and positional changes.
