少年期上中切牙冠根指标的锥体束CT研究
|
摘要
目的研究少年期上中切牙冠根长度,并探讨与之相关的硬组织测量指标。方法选取100例符合纳入标准的错牙合畸形患者的锥体束CT(CBCT)资料,运用MIMICS 17.0软件测量该100例患者的上中切牙冠根长度及与之相关的硬组织3D测量指标,运用SPSS 21.0统计软件对上中切牙冠根长度及相关硬组织3D测量指标进行Spearman相关性分析。结果少年期上中切牙:(1)根长与唇倾度和根尖唇侧牙槽骨厚度呈正相关;(2)冠根比与唇倾度以及根尖唇侧牙槽骨厚度呈负相关;(3)根尖唇侧牙槽骨厚度与唇倾度呈正相关,与冠根比呈负相关。结论少年期上中切牙根长、冠根比、唇倾度和根尖唇侧牙槽骨厚度之间存在相关性,对临床工作有指导意义。
Objective To investigate the crown-root length of upper central incisors in early youth and explore the related hard tissue measurement items. Methods The cone-beam CT( CBCT) materials of 100 patients with malformed malocclusion,who met the inclusion criteria,were selected. The crown-root length of the upper central incisors and the related hard tissue 3D measurement indexes were measured by MIMICS 17.0 software. The Spearman correlation analysis was carried out on the crown-root length of the upper central incisors and the related hard tissue 3D measurement indexes using the SPSS 21.0 software. Results(1)The root length was positively correlated with the lip inclination and the thickness of the alveolar bone in the apical labial side.(2)The crown root ratio of the upper central incisors was negatively correlated with the lip inclination and the thickness of the alveolar bone in the apical labial side.(3)The thickness of the alveolar bone in the apical labial side was positively related to the lip inclination,while negatively correlated with the crown root ratio. Conclusion There is a correlation between the length of the root,the crown root ratio,the lip inclination,the thickness of the alveolar bone in the apical labial side of the upper central incisors,which has some guiding significance for the clinical work.
