摘要: 目的:通过评估鼻腭管形状特征及其与上颌中切牙的距离,探讨鼻腭管(NPC)的形态计量特征对预期牙移动的影响。方法:选择符合纳入标准的200例CBCT影像资料,在矢状面上对鼻腭管进行分类,测量切牙孔直径、鼻腭管长度、切牙孔的前后直径(A-P IF)、斯坦森孔前后直径(A-P NF)和鼻腭管1/2长度处的直径(M-L IF)以及鼻腭管和中切牙牙根之间的距离。采用SPSS 26.0 软件包对数据进行统计学分析。结果:4种形状鼻腭管中,切牙孔直径(P=0.045)、A-P IF(P=0.001)、M-L IF(P<0.001)、A-P NF(P<0.001)差异具有统计学意义。通过线性回归分析不同截面上不同形态鼻腭管与中切牙牙根之间的距离关系发现,圆柱形鼻腭管在鼻腭管长度上显著相关;漏斗形鼻腭管在A-P IF和鼻腭管长度上显著相关。沙漏形鼻腭管在A-P IF、A-P NF和鼻腭管长度上显著相关。结论:不同形状鼻腭管都对不同截面鼻腭管直径和其到中切牙牙根的距离有一定影响。

Abstract: PURPOSE: The aim of this study was to evaluate the impact of the nasopalatine canal(NPC) shape and its morphometric characteristics on expected teeth movement by assessing the distance to maxillary central incisors (MCIs) according to NPC type. METHODS: A total of 200 patients with CBCT imaging data meeting the inclusion criteria were selected. The nasopharyngeal canal in the sagittal plane was classified. The following parameters were obtained: incisor foramen diameter, nasopalatine canal length, anterio-posterior diameter of incisor foramen (A-P IF), anterio-posterior diameter of Stenson foramen (A-P NF), nasopalatine tube 1/2 length diameter(M-L IF), and the distance between NPC and MCIs. The data were analyzed with SPSS 26.0 software package. RESULTS: Diameter of incisor hole(P=0.045), A-P IF(P=0.001), M-L IF(P<0.001), A-P NF(P<0.001) had significant difference. In cylindrical-shaped NPC, a significant correlation was observed for NPC length, while in funnel-shaped NPC, a significant correlation was observed for A-P IF and NPC length. In hourglass-shaped NPC, a significant correlation was observed for A-P IF, A-P NF, and NPC length. CONCLUSIONS: Each NPC shape showed specific impacts on the relationship between NPC diameters at different sections and distances to MCIs.
