Abstract
Introduction: Digital impressions represent a relatively new advancement in dentistry, with numerous intraoral scanning devices available that differ widely in features, capabilities, and measurement accuracy. Understanding how these digital methods compare to traditional measurement techniques is essential for evaluating their reliability and effectiveness. This study aimed to compare the accuracy of arch dimension measurements obtained through digital scanning and photographic assessment, using manual measurement as a reference standard.
Materials and methods: Fifteen dental study models, seven mandibular and eight maxillaries were measured using digital scanning and photographic assessment, with manual measurements serving as the reference standard.
Results: The findings demonstrate that digital scanning yields significantly higher accuracy than photographic assessment. The mean absolute error (MAE) between digital scans and manual measurements averaged 0.91 mm, considerably lower than the 2.29 mm MAE for photo-based measurements. Additionally, the mean relative error (MRE) for digital scanning was 13%, markedly less than the 31% error recorded for photographic methods.
Conclusion: These results indicate that digital scanning measurements deviate less from manual standards and thus provide a more precise assessment of dental models. The study reinforces the potential of intraoral digital scanning as a reliable and accurate alternative for dental arch measurement, contributing valuable insights to the evolving field of digital dentistry.
