Subject. The article presents articulatory factors analysis that determine the long-term stability of orthodontic treatment results in patients with position anomalies of maxillary canines. Objectives. The aim is to determine the occlusive and articulatory factors of stability of orthodontic treatment results in patients with position anomalies of maxillary canines. Methodology. An open, prospective, controlled study was conducted. 39 patients were examined (average age 32,4 ± 2,5 years). The average duration of follow-up in the retention period was 2,5 ± 0,4 years. After 2 years from the beginning of the retention period, patients were divided into two groups: 1st group – persons with recurrent dental anomalies (n = 19); 2nd group – persons with stable treatment results (n = 20). The assessment of dynamic and static types of occlusion was carried out using virtual jaws models and Amann Girrbach virtual articulator (commercial version of the ExoCad 3.0 Galway software (DentalCAD). Results. In 1st group patients with dental anomalies recurrence the most common «occlusal map» features were: in central occlusion – randomly located occlusal contacts of various configurations and color codes, in protrusion – occlusal contacts on the lateral group of teeth (often on premolars), and asymmetric tracks on incisors, in laterotrusion – occlusal contacts of various localization and intensity on the displacement side (up to the central incisor) and the opposite side. In 2nd group persons with orthodontic treatment stable result the «occlusion map» looks like this: in central occlusion – symmetrical and same color coding cluster occlusal contacts, in protrusion – symmetrical and same intensity tracks on central incisors and absence lateral teeth occlusion, in laterotrusion – canine and lateral teeth group occlusal contacts of uniform intensity only on displacement side. Conclusions. Thus, the static and dynamic occlusion assessment in patients with maxillary canines anomalies in the retention period showed that chance of stable result of orthodontic treatment are higher in cases of compliance with principles of functional occlusion of continuous dental arches.
