OBJECTIVE

The aim of the study is to evaluation of the quality of orthodontic treatment by comparing the severity of signs of distal occlusion before the start of orthodontic treatment and after its completion.

MATERIAL AND METHODS

Quantitative assessment of the severity of distal occlusion in 83 patients aged 17 to 30 years before and after orthodontic treatment. Depending on the chosen treatment algorithms, the patients were divided into 3 groups. The first group — 34 people — treatment included the use of a functional non-removable orthodontic device (FNT). The second group — 21 people — the treatment was accompanied by the removal of individual teeth of the upper jaw and the retraction of a group of front teeth of the upper jaw. Patients of the 3rd group — 28 people — underwent combined orthodonto-surgical treatment. The severity of distal occlusion was assessed using 3D cephalometric analysis data. To obtain a subjective assessment of the quality of orthodontic treatment, patients were asked to fill out questionnaires before and after orthodontic treatment.

RESULTS

The severity of distal occlusion decreased as much as possible as a result of treatment of the first group in 23.07% of patients and the third group (16.63%), which is interpreted by the formulation «significant improvement» of the dental anomaly. Patients of the first and third groups had a high degree of satisfaction with the result of treatment, according to the quantitative assessment of the questionnaire. The severity of distal occlusion in the second group was reduced to a lesser extent (55.5%), compared with the first and third groups, which is interpreted as «moderately improved». Patients noted an average degree of satisfaction with the result of treatment, as the implemented treatment plan did not meet their expectations in the aesthetic aspect.

CONCLUSION

The use of FNT for the extension and normalization of the position of the lower jaw is justified in the case of refusal of patients from combined orthodonto-surgical treatment, as it allows to fully solve the functional, aesthetic and psychological problems of patients, which contributes to improving their quality of life.
