摘要
介绍：在口腔正畸的诊断和规划中，牙弓模型的使用至关重要。专业人士对数字模型和打印模型的需求不断增加：研究旨在评估从数字模型、打印模型和直接测量中获得的水平和垂直线性测量值的一致性：材料： 采集了 30 个人的口内扫描图像。使用 STL 文件进行数字化测量。使用数字卡尺对打印模型进行测量，并直接对患者口腔进行实际测量：单样本 t 检验显示，两组配对测量结果之间没有差异，数值为 0（p>0.05）。采用布兰-阿尔特曼（Bland-Altman）分析法对成对测量结果进行评估。三种方法的水平和垂直测量结果显示一致。线性回归分析显示数据没有比例偏差（p>0.05）：在数字模型、打印模型和直接在个人口腔中进行测量时，水平和垂直测量结果显示一致。
Evaluation of the agreement of horizontal and vertical linear measurements obtained from digital models, printed models and direct measurements.
Introduction: The use of arch models is essential in diagnosis and planning in orthodontics. The demand for digital and printed models has increased among professionals.
Objective: The aim of the study was to assess the agreement of horizontal and vertical linear measurements obtained from digital models, printed models, and direct measurements.
Materials and methods: Intraoral scans of 30 individuals were obtained. Digital measurements were performed using the STL files. From printed models, the measurements were done using a digital caliper, and the real measurements were done directly to the mouth of respective patients.
Results: The one-sample t test showed no discrepancy between the paired sets of measurements, with the value of 0 (p>0.05). The evaluation of the measurements was done using Bland-Altman analysis in pairs. The three methods showed agreement in horizontal and vertical measurements. Linear regression analyses showed no proportional bias in the data (p>0.05).
Conclusion: The horizontal and vertical measurements evaluated showed agreement when measured on digital models, printed models and directly in the individuals' mouths.
