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.
