Effectiveness of preoperative orthodontic therapy of an adolescent with skeletal form of mesial occlusion according to X-ray profilometry

Abstract

The aim of the study is a comparative analysis of the parameters of profile teleradiographs of the head of a teenager in the dynamics of orthodontic preparation for the surgical stage of treatment. Migration of individual teeth at the stage of orthodontic treatment led to the change in the inclination of occlusal plane (Ocp) relative to the jaw base and to the increase of the value of Wits index. In this regard, in order to clarify the volume of interventions at the surgical stage of patient’s rehabilitation, it is necessary to conduct dynamic comparative analysis of profile teleradiographs of the head obtained before and after the completion of pre-surgical stage of orthodontic treatment. The authors consider it appropriate to analyze the relative position and correspondence of the sagittal dimensions of the upper (NL) and lower (ML) jaws to the anterior section (SN) of the skull base, and to take into account the size of the chin protrusion determining the position of Pg point when measuring the profile angle and facial aesthetics according to Rickets.
