【摘要】：目的用锥形束CT(CBCT)分析上颌前牙区鼻腭管及唇侧骨的形态。方法收集并筛选出712例正常人上颌前牙区CBCT影像,对其鼻腭管、唇侧骨的相关参数进行测量分析。结果研究对象年龄范围在5~80岁,男306例(43.0%),女406例(57.0%)。鼻腭管矢状面平均长度为(13.58±2.22)mm,矢状面平均直径为(3.37±1.58)mm,唇侧骨矢状面平均厚度为(7.63±1.50)mm,鼻腭管直径与唇侧骨厚度相对值为0.46±0.19,长度相对值为0.69±0.10。结论各年龄段人群之间鼻腭管的直径、长度和唇侧骨厚度存在一定差异。儿童的鼻腭管直径小于成人(P0.000 1),唇侧骨厚度大于成人(P0.000 1)。随着年龄的增长,鼻腭管直径和长度均呈递增趋势,唇侧骨厚度递减。男性的鼻腭管直径、长度和唇侧骨厚度、长度均大于女性。
[Abstract]:Objective to analyze the morphology of nasopalatine canal and labial bone in maxillary anterior teeth by CT-CT-CT.Methods CBCT images of maxillary anterior teeth were collected and screened in 712 normal subjects, and the nasopalatine canals were analyzed. The related parameters of labial bone were measured and analyzed. The average length of sagittal plane of nasopalatine tube was 13.58 卤2.22 mm, the average diameter of sagittal plane was 3.37 卤1.58 mm, the average thickness of sagittal plane of lip was 7.63 卤1.50 mm, the relative value of diameter of nasopalatine duct to labial bone was 0.46 卤0.19 and the relative value of length was 0.69 卤0.10.Conclusion the average thickness of sagittal plane of lip is 0.46 卤0.19. The diameter of the nasopalatine canal between the crowd, The diameter of nasopalatine canal in children was smaller than that in adults (P 0.000 1), and the thickness of lip bone was larger than that in adults (P 0.000 1). The diameter and length of nasopalatine canal increased with age. The diameter and length of nasopalatine canal and the thickness and length of labial bone were all larger in males than in females.
