This study was carried out aiming to investigate the accuracy of measurements , differences in linear and angular measurements of the craniofacial complex using both the two and three dimensional method of measuring in patients with different kinds of malocclusion ; and also to compare each kind of malocclusion to the others. The sample of the study consisted of 40 patients , divided into three groups – a group for each skeletal malocclusion , Cone Bean Computed Tomography (CBCT) was performed for each patient , then two dimensional radiographs were derived from the CBCT ; after performing the measuring , collecting the results and analyzing them statistically.
