Brief summary

The aim of the study is to quantify the differences in the diagnostic relationships between Centric occlusion versus maximum intercuspation in adult orthodontic patients with Cetric relation recoded using both conventional method utilizing semi-adjustable articulator and face bow record in addition to digital method proposed by Radu et al for finding and recording CR using a dental intraoral scanner with a leaf gauge
