[Abstract]:Objective: to measure the thickness of alveolar bone on the labial side of maxillary anterior teeth in Xinjiang Uygur adults by conical beam CT, and to understand the anatomical morphology of alveolar bone in maxillary anterior teeth of Uygur adults. To provide theoretical basis for preoperative evaluation and selection of treatment regimen in this area. Methods: from August 2013 to June 2016, 85 Uygur adults admitted to the first affiliated Hospital of Xinjiang Medical University were selected for CBCT data, including 40 males and 45 females, with an average age of (24.3 鹵3.5) years. A total of 510 maxillary anterior teeth were selected. The inclusion criteria were as follows: no significant overbite of maxillary anterior teeth, normal overbite, no loss of maxillary anterior teeth, no restoration and filling of maxillary anterior teeth, healthy periodontal tissue, no history of orthodontic treatment, no obvious fracture of maxilla and bone defect. A systemic disease that does not affect bone metabolism. At 2 mm below the crest of the median alveolar bone of the labiopalatine side, the middle of the root and the apical part of the root were straight line perpendicular to the measured sagittal plane to measure the thickness of the alveolar bone of the labiopalatine side. The sagittal position relationship between the root and alveolar bone of maxillary anterior teeth was analyzed qualitatively. SPSS 17.0 statistical software was used to analyze the result data. Single factor analysis of variance (ANOVA) was used to compare the thickness of alveolar bone measured by conical beam CT and LSD-t test was used to measure the thickness of alveolar bone. The test level was 0. 05 for both sides. Results the sagittal position of the maxillary anterior root was in the first class, and the sagittal position of the maxillary anterior root in the proximal labial cortex was 3.3% (17 / 510). The sagittal position of the root in the proximal palatine cortex was 8.0% (41 / 510), and the alveolar bone thickness was only 1. 1% (11 / 1020) at 2 mm below the crest of the labial crest of the maxillary anterior tooth and only 1. 1% (11 / 1020) of the alveolar bone thickness at the same time. The thickness of alveolar bone was 2 mm below the top of the alveolar crest of the labial and palatal side of the anterior teeth, and the mean thickness of the middle root and the root apex. The thickness of alveolar bone perpendicular to the root long axis of maxillary anterior teeth was 2 mm below the top of alveolar crest. The thickness of alveolar bone perpendicular to the long axis of the root is 2 mm below the alveolar crest in the middle of the root of the maxillary anterior teeth. Conclusion: the root position of maxillary anterior teeth of Uygur adults in Xinjiang is mostly inclined to the labial side, and the thickness of alveolar bone wall of the labial and palatal side is different, and the alveolar bone wall of the labial side is thinner.
