摘要
背景:牙槽嵴裂患者植骨后骨存量目前多使用二维影像进行分析测量,结论误差较大。目的:探讨锥形束CT评价牙槽嵴裂植骨后6个月成骨效果的应用。方法:随机抽取25例单侧完全性牙槽嵴裂的患者,进行牙槽嵴裂髂骨移植,6个月后采用锥形束CT进行观察。结果与结论:牙槽嵴裂骨移植后,唇侧牙槽骨保存量较腭侧高;另外中切牙裂隙侧与正常侧的牙槽骨厚度差异有显著性意义,而尖牙缺隙侧与正常侧牙槽骨厚度在距离牙槽嵴顶0 mm处的牙槽骨厚度处差异有显著性意义,其余部位差异无显著性意义。说明牙槽嵴裂骨移植时腭侧支持骨少于唇侧,缺隙侧中切牙的支持骨也不理想,从而为牙槽骨移植和正畸治疗牙齿移动提供依据。
BACKGROUND： In alveolar cleft patients, the amount of bone stock after alveolar bone grafting is mostly measured and analyzed by two-dimensional imaging, which can result in a large error. OBJECTIVE： To evaluate the 6-month osteogenesis of alveolar bone graft in alveolar cleft patients using cone beam CT. METHODS： Alveolar bone grafting was performed in 25 patients with unilateral complete alveolar cleft. The patients were followed up for 6 months after surgery and the osteogenesis of the bone graft was evaluated by CBCT. RESULTS AND CONCLUSION： After the surgery, the labial bone support was better than the palatal one. There were significant differences in the alveolar bone thickness of the cleft region and the normal region of the central incisor as well as the alveolar bone thickness of the cleft region and the normal region of the canine tooth 0 mm distant to the alveolar crest. These findings indicate that the palatal bone support is less than the labial one, and the bone support of the central incisor is not satisfactory, which provide the basis for the tooth movement in the alveolar bone grafting and the orthodontics treatment.
