不同年龄组牙槽嵴裂植骨术后牙槽嵴高度的临床观察

目的：评价在不同年龄阶段髂骨松质骨移植修复牙槽嵴裂术后植入骨的变化情况。方法：根据牙槽嵴裂患者裂隙侧尖牙萌出情况，将其分为A、B两组，通过牙槽嵴裂植骨术后临床随访和拍摄X线，追踪观察植骨区牙槽嵴高度的变化。结果：尖牙萌出前植骨优于尖牙萌出后植骨，术后正畸可增高牙槽嵴的高度。结论：牙萌出可增高牙槽嵴裂患者植骨术后牙槽嵴的高度。

Clinical observation of the height of the alveolar after bone grafting in cleft alveolar repair in various ages

PURPOSE: To evaluate the changes of transplanted bones after cancellous iliac bone grafting in cleft alveolar repair in various ages. METHODS: The patients were divided into A and B groups according to their canine eruption. The changes of alveolar height in grafting regions were examined by clinical follow up and radiographs after the cancellous iliac bone grafting in cleft alveolar repair. RESULTS: The bone grafting before the eruption of canines was more effective than that after eruption. The orthodontics after operation can increase the alveolar height. CONCLUTION: The alveolar height after the bone grafting in cleft alveolar repair increased with the eruption of canines.
