Objective: To c ompare 3 D d igital study models with respect to their efficiency in reproducing
the details when compared with conventional methods.
Materials and Methods: Sixty orthodontic study models were measuring Bolton’s analysis, ideal arch analysis and tooth width analysis both in conventional and digital methods. In conventional method Vernier caliper and brass wire were used while in digital method 3D 3E digital scanner and Ortho Analyzer software program were used for model analysis.
Results: To analyze the difference between measurement values, t-test was used for data with normal distribution. There was no significant difference between the conventional and digital methods in boltons analysis, ideal arch analysis and tooth width analysis. Conclusion: There was no difference between the efficacy of conventional and digital methods. Both the methods are as reliable in assessing the study models.
