AIM: This study evaluated the accuracy of dental measurements made on plaster models compared with blue cam images and digital photographs. MATERIALS AND METHODS: The study sample comprised pre-treatment diagnostic study models of 10 randomly selected subjects divided into three subcategories. CAD CAM and photo graphs of the model were taken and digitally analysed. Plaster models were analysed with a vernier caliper results were obtained. ANOVA test was done to determine the statistical significance. RESULTS: The dental measurements made on the two newer methods of study model analysis (FACAD and Blue-cam Generated digital models), compared to the conventional technique of direct measurement on plaster model using digital Vernier caliper, although revealed slight variations in numerical values, did not show statistically significant difference in any of the twelve dental parameters measured CONCLUSION: Digital measurement using photographs in FACAD and Blue CAM generated digital models can be used as an alternative to the conventional measurement of plaster models using a vernier caliper.
