摘要:
[摘要]目的：比较三维及二维头影测量差异，并初步建立Ricketts分析法测量项目的正常值范围。方法：样本由30名正常牙合
成人组成，同时拍摄锥形束CT（CBCT）和头颅侧位片，对Rickitts分析法的16个项目进行测量。CBCT图像导入Simplant O&O
软件进行三维头影测量。头颅侧位片用硫酸纸描图定点进行二维头影测量。用组内相关系数(ICC)评价操作者的测量信度，
采用配对t检验对两组间的差异进行比较。结果：10个测量项目的测量结果具有统计学意义，包括软组织测量项目：Ls-EP，
Em-OP；角度：FH-NPog，MP-NPog，FH/NA，PP-FH，FH-MP，BaN-FH；线距：L1-APog，L1-OP。CBCT组ICC均值为0.871,2D组
为0.935。结论：CBCT的测量与头颅侧位片的测量结果中，10个测量项目的测量结果比较有显著性差异，CBCT的可靠度和精
确性较好。初步推断出哈尔滨地区Ricketts分析法部分参数的CBCT三维头影测量正常牙合参考值范围。

Abstract:
Abstract: Objective To compare the differences between the three-dimensional and two-dimensional cephalometric
measurements and to establish the normal value range of the project. Methods The samples were composed of 30 normal tooth
synthesizers, and the CBCT and Lateral cephalometric radiograph were taken to measure the 16 items of Rickitts analysis.
The CBCT image was imported into Simplant O& O software for 3D cephalometric measurement. The Lateral cephalometric
radiograph was measured with the point of the sulfate paper. The correlation coefficient (ICC) was used to evaluate the
measurement reliability in the operator, and the difference between the two groups was compared by the paired t test. Results
The measurement results of 10 measurement items were statistically significant, including the soft tissue measurement project:
Ls-EP, Em-OP; Angle: FH-NPog, MP-NPog, FH/NA, PP-FH, FH-MP, BaN-FH; Line distance: L1-APog, L1-OP. The ICC mean
of CBCT group is 0.871, and the 2D group is 0.935. Conclusion The measurement results of CBCT and Lateral cephalometric
radiograph were significantly different in 10 measurement items, and the reliability and accuracy of CBCT group were better
than that of 2D group. It is inferred that the three-dimensional cephalometric of the CBCT of partial parameters of the Ricketts
analysis method in the Harbin region is used to measure the normal tooth conjoint reference range.
