OBJECTIVES
The purpose of this study was to evaluate the accuracy and reliability of inter-arch measurements using digital dental models and conventional dental casts.
METHODS
Thirty sets of dental casts with permanent dentition were examined. Manual measurements were done with a digital caliper directly on the dental casts, and digital measurements were made on 3D models by two independent examiners. Intra-class correlation coefficients (ICC), a paired sample t-test or Wilcoxon signed-rank test, and Bland-Altman plots were used to evaluate intra- and inter-examiner error and to determine the accuracy and reliability of the measurements.
RESULTS
The ICC values were generally good for manual and excellent for digital measurements. The Bland-Altman plots of all the measurements showed good agreement between the manual and digital methods and excellent inter-examiner agreement using the digital method.
CONCLUSION
Inter-arch occlusal measurements on digital models are accurate and reliable and are superior to manual measurements.
目的
本研究旨在评估使用数字化牙科模型和传统石膏模型进行牙弓间测量的准确性和可靠性。
方法
检查了30套恒牙列石膏模型。使用数字卡尺直接在石膏模型上进行手动测量，并由两名独立检查者在三维模型上进行数字测量。使用组内相关系数（ICC）、配对样本t检验或Wilcoxon符号秩检验以及Bland-Altman图来评估检查者内和检查者间误差，并确定测量的准确性和可靠性。
结果
ICC值对于手动测量总体良好，对于数字测量则非常出色。所有测量的Bland-Altman图显示手动和数字方法之间具有良好的一致性，并且使用数字方法时检查者间一致性极佳。
结论
数字化模型上的牙弓间咬合测量准确可靠，且优于手动测量。
