RESUMO
Distal occlusion of the dentition is one of the most common anomalies in the Eastern European population. The widespread use of conservative treatment methods creates the need to predict the results of tooth movement. The problem of the influence of orthodontic treatment on the configuration of the soft tissues of the face is of paramount importance for the orthodontist. Purpose of the study: to evaluate changes in the profile of the face during orthodontic treatment of distal occlusion due to anteposition of the upper jaw. 13 patients aged 18-30 years with distal occlusion caused by anteposition of the upper jaw were examined and treated. A standard examination was carried out, including clinical, anthropometric and radiological diagnostic methods. Orthodontic treatment of all patients was carried out, including the removal of individual teeth in the upper jaw. The study shows the features of changing the configuration of the soft tissue profile of the face in the treatment of patients with distal occlusion of the dentition. As a result of orthodontic treatment, the position of the jaws in the sagittal and vertical planes remained practically unchanged. The soft tissue profile of the face was affected by a change in the position of the incisors. A thorough diagnosis of dentoalveolar anomalies, identification of facial configuration features and knowledge of the changes that accompany orthodontic movements will lead not only to the normalization of occlusion and function, but also to the harmonization of the soft tissues of the face.
