Comparison of Digital Measurement versus Physical Model Measurement: An Analysis of Accuracy and Precision.
Author(s): Smith DK, Beaudoin B, Messersmith M and Blume JD
Objective: The objective of this study was to compare the accuracy and precision of digital model measurement to physical measurement of orthodontic models.
Methods: To assess accuracy, teeth were removed from a typodont and measured individually to obtain a gold standard measurement A stone model of the typodont was then measured n=75 times by both digital and physical measurement and these measurements were compared to the gold standard. To assess precision, patient
models (n=27) were measured five times each by each method and assessed via an intra-class correlation coefficient.
Results: The accuracy analysis suggested that measurements of individual tooth width, archlength, and crowding were all more significantly more accurate using the digital measurement techniq... view more»
