Evaluation of virtual models (3Shape Ortho System) in assessing accuracy and duration of model analyses based on the severity of crowding
The Saudi Journal for Dental Research
Objective: The purpose of this study was to determine the accuracy and time taken to perform the space analysis (arch length discrepancy and Bolton's) based on the severity of crowding using new virtual model software (3Shape Ortho System, 3Shape A/S, Copenhagen) with that of conventional plaster models. Materials and methods: Models from 45 patients, divided into three groups based on the severity of crowding (group 1: <2.5 mm, group 2: 2.5-5 mm, and group 3: >5 mm) were included in thisdoi:10.1016/j.sjdr.2016.05.004 fatcat:ids5av5rpnhibbxdud3hzvihxy
