Abstract

Abstract Objectives To compare the measurement of cephalometric parameters using 3D images obtained from CBCT to 2D images obtained from a conventional cephalogram. Methods An electronic literature search was conducted using PubMed, Embase, Web of Science, CNKI, CENTRAL, and the grey literature database of SIGLE (up to May 2021). The selection of the eligible studies, data extraction, and an evaluation for possible risk of bias (Quality Assessment of Measurement Accuracy Studies tool) were performed independently by two authors. Inconsistencies were judged by a third author. Statistical pooling, subgroup analysis, a sensitivity analysis and an evaluation of publication bias were performed using Comprehensive Meta-Analysis (version 2.2.064, Biostat, Englewood, NJ). Results A total of eight articles were eligible for final meta-analysis. The differences in two of the skeletal measurement parameters [Ar(Co)-Gn, Me-Go] and one of the dental measurement parameters (U1-L1) were found to be statistically significant when using CBCT and conventional cephalograms (P = 0.000, P = 0.004, P = 0.000, respectively). Conclusions CBCT can be used as a supplementary option to support conventional cephalometric measurements. In clinical situations in which three-dimensional information is required, patients can benefit from CBCT analysis to improve diagnosis and treatment planning.

二维和三维头颅测量准确度的比较:系统回顾和荟萃分析

目的比较CBCT三维图像与常规脑电图二维图像的测量参数。方法采用PubMed、Embase、Web of Science、CNKI、CENTRAL和SIGLE灰色文献数据库(截至2021年5月)进行电子文献检索。合格研究的选择、数据提取和可能的偏倚风险评估(测量准确性研究质量评估工具)由两位作者独立完成。不一致由第三位作者判断。采用综合meta分析(version 2.2.064, Biostat, Englewood, NJ)进行统计池、亚组分析、敏感性分析和发表偏倚评价。结果共有8篇文章符合最终meta分析的条件。使用CBCT与常规脑电图时，两项骨骼测量参数[Ar(Co)-Gn, Me-Go]和一项牙齿测量参数(U1-L1)的差异均有统计学意义(P = 0.000, P = 0.004, P = 0.000)。结论CBCT可作为常规头颅测量的补充选择。在需要三维信息的临床情况下，患者可以从CBCT分析中受益，以提高诊断和治疗计划。

期刊介绍： The Australasian Orthodontic Journal (AOJ) is the official scientific publication of the Australian Society of Orthodontists. Previously titled the Australian Orthodontic Journal, the name of the publication was changed in 2017 to provide the region with additional representation because of a substantial increase in the number of submitted overseas'' manuscripts. The volume and issue numbers continue in sequence and only the ISSN numbers have been updated. The AOJ publishes original research papers, clinical reports, book reviews, abstracts from other journals, and other material which is of interest to orthodontists and is in the interest of their continuing education. It is published twice a year in November and May. The AOJ is indexed and abstracted by Science Citation Index Expanded (SciSearch) and Journal Citation Reports/Science Edition.
