(1) Background: Modern imaging methods and constantly developing technologies extend the range of diagnostic tools in medicine and in orthodontics. Thanks to them, scientists and doctors can use devices designed to diagnose 3D structures of the human body. The aim of the study was to assess the usefulness of digital orthodontic models as a diagnostic tool in the work of an orthodontist through a comparative analysis of the value of orthodontic measurements made on traditional plaster models and virtual models. (2) Methods: A total of 80 sets of models were made, including 40 sets of plaster models and 40 sets of digital models. A total of 48 diagnostic parameters were developed. They concerned dental parameters. (3) Results: Comparative analysis of crown height values on plaster and digital models showed statistically significant differences ( < 0.05) in 26 out of 48 dental parameters. (4) Conclusions: The differences between the measurements made with the software on the digital models and the measurements made with the traditional method of measurement using the digital caliper on the plaster models were small and clinically acceptable.
(1) 背景：现代成像方法和不断发展的技术扩展了医学和正畸学中诊断工具的范围。借助这些方法和技术，科学家和医生能够使用旨在诊断人体三维结构的设备。本研究的目的是通过对在传统石膏模型和虚拟模型上进行的正畸测量值进行比较分析，评估数字正畸模型作为正畸医生工作中的诊断工具的实用性。(2) 方法：共制作了80套模型，包括40套石膏模型和40套数字模型。总共制定了48个诊断参数。这些参数涉及牙齿参数。(3) 结果：对石膏模型和数字模型上牙冠高度值的比较分析显示，在48个牙齿参数中的26个参数上存在统计学上的显著差异（<0.05）。(4) 结论：使用软件在数字模型上进行的测量与使用数字卡尺在石膏模型上采用传统测量方法进行的测量之间的差异很小，在临床上是可以接受的。
