Recently, secondary bone grafting for the alveolar cleft of cleft lip and palate patients has carried out generally with the object of connecting the alveolar cleft, of leading the tooth eruption, of control the tooth axis. In this study, the experimental tooth movements to the area were tested and the histological changes were investigated with adult cats.<BR>The experimental defects of 2mm in diameter were made at the alveolar bone mesial to the both maxillary first molar. At the experimental side, DBP were stuffed into the defect. Only defects were made at the control side. The tooth were moved for 6 weeks.<BR>The restoration of the defect hadn't occurred at the control side after 14 weeks. While appositional bone growth and new bone formation surrounding the DBP were observed, and complete restoration had be already occurred at experimental side after only 8 weeks. In the group which tooth movement were started after 1 week, the existing alveolar bone were bent to mesial at both side.<BR>In the group were started after 8 weeks, the existing alveolar bone were bent to mesial at the control side, either. The DBP and new bone were resorbed at the same time at the experimental side.
