锥形束CT数字成像分析对牙槽嵴裂植骨修复价值分析

The Value of Cone-Beam CT Digital Imaging Analysis in Repairing Alveolar Cleft Bone Graft

目的:分析牙槽嵴裂植骨修复后锥形束CT数字成像的扫描价值。方法:选取口腔科在2018年4月~2019年6月收治的单侧完全性牙槽嵴裂患者共33例,其中男性15例,女性18例;年龄8~14岁,平均(11.61±1.33)岁。完成植骨手术后半年展开锥形束CT数字成像分析,观察中切牙、尖牙的健侧、裂隙侧与牙槽嵴顶M0、M1、M2、M4处牙槽骨厚度以及牙颈部至牙槽嵴顶距离。结果:中切牙健侧及裂隙侧M0、M1、M2、M4呈显著差异,尖牙仅M0呈显著差异;中切牙健侧及裂隙侧牙颈部至牙槽嵴顶呈显著差异,尖牙无明显差别。结论:牙槽嵴裂植骨修复下唇侧支持骨优于腭侧,缺隙侧中切牙恢复未达理想程度,锥形束CT可获取清晰图像并提供有效数据参考。

Objective:To analyze the scanning value of cone-beam CT digital imaging after bone grafting for alveolar cleft.Methods:A total of 33 patients with unilateral complete alveolar cleft admitted to the department of stomatology from April 2018 to June 2019 were selected,including 15 males and 18 females.The age range ranged from 8 to 14 years old,with an average age of(11.61±1.33)years old.Cone-beam CT digital imaging analysis was performed half a year after the completion of the bone graft surgery to observe the central incisor,the healthy side of the canine,the fissure side and the alveolar crest M0,M1,M2,M4.The thickness of the alveolar bone and the distance from the neck of the tooth to the crest of the alveolar.Results:M0,M1,M2,and M4 on the healthy side of the central incisor and the fissure side were significantly different,and the canine was only M0 showed a significant difference;there was a significant difference between the healthy side and the fractured side of the central incisor from the neck to the alveolar crest,and there was no significant difference between the canines.Conclusion:Alveolar ridge fissure repair with bone grafting.The supporting bone of the lower labial side is better than the palatal side,and the restoration of the central incisor on the gap side is not up to the ideal degree.Cone beam CT can obtain clear images and provide effective data reference.
