Faculty of Dental Medicine – Plovdiv, Bulgaria and Orthodontic Department would like to thank AudaxCeph for the opportunity to have been working with one of the most contemporary cephalometric analysis software for free since 2016.
The teachers in the department use AudaxCeph in their studies. AudaxCeph also benefits students training and undergraduates in the department.
AudaxCeph features allow orthodontists to perform digital cephalometric analysis to detail the treatment plan, predicts the changes during skull growth and enables a virtual simulation of the expected results of orthodontic treatment.
