Objectives: This study aimed to evaluate the accuracy and reliability in measuring anchorage loss, molar rotation, and total amount of retraction using cone beam computed tomography (CBCT) and to compare them with the same measurements obtained using digitally scanned dental models. Materials and methods: 24 patients requiring comprehensive orthodontic treatment including extraction of 1st premolars with maximum anchorage using enmasse retraction. CBCTs were undertaken on the same 24 patients using InVivoDental software for measurement. The digital cast was made using alginate impressions, from which virtual 3D models will be created and measured using 3Shape analyzer software. Orthodontic measurements will be obtained from both the CBCT and the digital dental casts using standardized software. Three orthodontists will independently measure these parameters to evaluate inter- and intra-examiner reliability. Results: Preliminary results indicate a high level of agreement between orthodontic measurements acquired from CBCT and digital casts in the assessment of anchorage loss, molar rotation, and total amount of retraction. The ICC values revealed strong intra-examiner and inter-examiner reliability between the two measurement methods. Conclusion: This study supports the comparability of orthodontic measurements acquired from digital casts and CBCT in assessing anchorage loss, molar rotation, and the total amount of retraction
