摘要：

文题释义：
锥形束CT：是锥形束投照计算机重组断层影像设备，其原理是X射线发生器以较低的射线量(通常球管电流在10 mA左右)围绕投照体做环形数字式投照，多次(180-360次)数字投照后，集中所获得的数据在计算机中重组，进一步获得三维图像。锥形束CT具有放射剂量小，成像效率高，费用较为低廉，操作使用方便等诸多优点，是近年来被广泛应用于口腔颌面部的影像学检查手段。
微螺钉种植体：微种植体支抗是一种可以不依赖于患者配合、体积小、操作简便、植入部位选择相对灵活的绝对支抗装置，在正畸临床治疗中的应用日趋普遍。目前，微螺钉型种植体支抗被广泛应用于正畸治疗中，也是压低上颌前牙、解除前牙深覆牙合时较为理想的辅助手段。

背景：目前，关于上颌前牙区骨厚度的研究较少，且国内研究多集中于中国南方汉族人群，对于新疆地区维吾尔族人群性别之间是否存在差异尚不可知。
目的：测量新疆地区维吾尔族成年人上颌前牙区的颌骨厚度，并分析男女性别差异性。
方法：收集采用锥形束CT技术拍摄的新疆地区维吾尔族成年人120例(男、女各60例)，选择切牙间、中切牙与侧切牙间、侧切牙与尖牙间矢状面在距离参考平面14，17，20 mm 3个种植钉植入高度处唇舌向骨质厚度。
结果与结论：在上颌中切牙之间、中切牙与侧切牙区的14，17 mm高度组中，维吾尔族男性的骨质厚度明显厚于维吾尔族女性；在上颌侧切牙与尖牙区的14 mm高度组中，维吾尔族男性的骨质厚度明显厚于维吾尔族女性。结果提示，维吾尔族成年人的上前牙区牙槽骨厚度有着性别差异，可以为正畸临床中微螺钉种植体的植入提供依据。

Abstract: BACKGROUND: At present, there are few studies on the bone thickness of the maxillary anterior teeth, and most domestic studies focus on the Han population in southern China. It is still unknown whether there are sex differences in the Uyghur population in Xinjiang.
OBJECTIVE: To measure the thickness of alveolar bone in the maxillary anterior area of Uygur adults in Xinjiang and analyze the sex difference. 
METHODS: Cone-beam CT data of 120 Uygur adults (60 males and 60 females) in Xinjiang were collected. The labiolingual thickness of the alveolar bone in the maxillary anterior area was selected at the height of 14, 17, and 20 mm from the reference plane in the sagittal plane between the incisors, between the central incisor and the lateral incisor, as well as between the lateral incisor and the canine. 
RESULTS AND CONCLUSION: In the 14 and 17 mm height groups between the maxillary central incisors and between the central incisors and the lateral incisors, the bone thickness of Uygur men was significantly thicker than that of Uygur women; in the 14 mm height group between the maxillary lateral incisors and the canine, the bone thickness of Uygur men was significantly thicker than that of Uygur women. To conclude, there is a sex difference in the thickness of alveolar bone in the maxillary anterior teeth of Uygur adults, which provides a basis for the implantation of microscrew implants in orthodontic clinic.
