ABSTRACT
The research was done on the basis of 47 CТ of TMJ of subjects with the orthognathic occlusion without any pathology of TMJ. The measurements of parameters aquired by CT of TMJ were taken by the personal computer with the use of the program EzImplant-Dental3D-Professional. Position of mandibular axis concerning orbital area is characterized by strength, but concerning the area po-po (external auditory meatuses) position of mandibular axis appears more variable. Received issues confirm existence of imprecisions by the use of face bow, which is aimed for transferal of models of jaws in articulator, what influences accuracy of articulator’s operation in the long run
