Abstract The study aims to compare the accuracy and reliability of tooth width measurements and Bolton ratios among plaster models (PM), cone beam computed tomography (CBCT), and intraoral scanner (IOS). This three-way comparison has not been previously conducted in existing studies. Seventy-two patients (aged 19–36) were selected from the University of Duhok clinic. PM, CBCT, and IOS images were obtained. Tooth widths and Bolton ratios were measured on plaster models and digital models (CBCT and IOS mages). Reliability was assessed by repeating all measurements after one month by the same examiner. The measurement accuracy and reliability were assessed through Repeated Measures ANOVA and ICC analysis. ICC results showed reliable measurements of tooth widths for PM, CBCT, and IOS ( R = 0.90, 0.98, and 0.99 respectively). P -values for tooth widths and Bolton ratios between groups were all > 0.05. The ICC analysis revealed a strong correlation between the measurements of tooth widths and Bolton ratios obtained through the three distinct methods. PM, CBCT, and IOS can be used interchangeably in orthodontic diagnosis for accurate and reliable measurement of tooth widths and Bolton ratios (anterior and overall).
