Alveolar cleft is the major problem during the formation of the ideal dental arch in cleft lip and/or palate patients. Since 1982, we have been treating patients with secondary alveolar bone grafting using autogenous particulate marrow and cancellous bone obtained from the iliac crest. Subsequently, teeth adjacent to the cleft into the grafted sites were repositioned orthodontically without any prosthesis. Sometimes, however, it is very difficult to achive the orthodontical closure of the arch without any prosthesis because of a too long orthodontical treatment period or a too wide cleft accompanied with congenitally missing teeth. Conventionally, prosthesis like denture or bridgework has been used for the dental reconstruction in these cases. Since 1993, we have applied Branemark Implant to the bone grafted alveolus in these cases. All patients with alveolar clefts received grafts of autogenous particulate cancellous bone obtained from the iliac crest except one case with periosteoplasty. After the bone bridge formation, orthodontical treatment and preparation for the implant placement were carried out. Seventeen Branemark fixtures were inlayed in 16 grafted alveoli. In 4 cases, in which the alveolar bone height was insufficient, chin bone grafts were used for the fixture placement. Free-standing final prosthesis was successfully applied in all cases.<BR>This is the first report of a systemical application of osseointegrated implant in cleft lip and/or palate patients, and this treatment procedure is one of the optional methods for the dental rehabilitation of patients with alveolar clefts after secondary alveolar bone grafting.
