摘要:

 目的 通过对比骨性Ⅲ类、正常 的锥形束CT(Cone beam CT,CBCT),比较两者之间骨性鼻基底的区别,为鼻基底凹陷的诊断治疗提供依据。方法 选取2020年1月至2023年12月就诊的40例患者(骨性Ⅲ类患者20例、正常者20例),测量CBCT相关数据并导入Simplant pro 11.04软件进行三维定点,比较两者骨性鼻基底的区别。结果 骨性Ⅲ类患者与正常者的上牙槽座点绝对/相对突度、鼻前点绝对/相对突度、双侧鼻旁-眶下点中点绝对/相对突度、双侧鼻旁点绝对/相对突度、双侧尖牙窝点绝对/相对突度差异有统计学意义(P<0.05)。结论 CBCT对辅助诊断鼻基底凹陷有一定意义,经三维重建测量后,骨性Ⅲ类患者的A点、AN点、B3点、mid-ParaN-D-IF点、ParaN点较正常 者后移。

Abstract:

Objective By comparing the Cone beam CT (CBCT) of bone class Ⅲ and normal occlusion, the difference of bony nasal base between them was compared to provide the basis for the diagnosis and treatment of nasal base depression. Methods From January 2020 to December 2023,40 patients (20 cases of bone class Ⅲ and 20 cases of normal occlusion) were selected, and the CBCT related data were measured and imported into Simplant pro 11.04 software for threedimensional fixed-point pointing, and the differences of nasal base between the two groups were compared. Results There
were statistically significant differences in the absolute/relative protrusion of the upper alveolar seat point, the absolute/
relative protrusion of the anterior nasal point, the absolute/relative protrusion of the bilateral paranasal and infraorbital points, the absolute/relative protrusion of the bilateral paranasal points, and the absolute/relative protrusion of the bilateral canine socket between the patients with bone class Ⅲ and the patients with normal combination (P<0.05). Conclusion CBCT has certain significance in the auxiliary diagnosis of nasal base depression, and after three-dimensional reconstruction measurement, the points A, AN, B3, mid-ParaN-D-IF and ParaN of bony Ⅲ patients are moved back compared with those
of normal patients.
