Abstract
Objectives: To investigate the validity, reliability and time spent on performing a full orthodontic study model analysis (SMA) on Cone Beam Computed Tomography (CBCT)-generated dental models (Anatomodels) compared with conventional Plaster models and a subset of Extracted Premolars. Methods: Timed SMA was performed on thirty retrospectively selected patient records. Five evaluators participated in the interrater reliability study and one evaluator for the intrarater reliability and validity studies. Agreement was assessed by ICC and crosstabulations while mean differences were investigated using paired-sample t-tests and repeated measures ANOVA. Results: For all three modalities studied—Anatomodels, Plaster and Extracted Premolars—intrarater reliability was excellent, interrater reliability was moderate to excellent, validity was poor to moderate, and performing SMA on Anatomodels took twice as long as on Plaster. Conclusions: SMA using CBCT-generated study models was reliable but not always valid and required more time to perform when compared with Plaster models.
