The purpose of the survey was to examine the main factors affecting the quality of orthodontic treatment. Materials and methods: the survey was conducted over 3 years in 158 orthodontists who participated advanced training in the Departments of Therapeutic Dentistry, Pediatric Dentistry and Orthodontics. A questionnaire was drawn up for the survey including 4 sets of questions: diagnosis, treatment planning, completion and retention, documentation. The results obtained suggest that doctors who were interviewed conducted a complex of diagnostic measures 49.37%, an aesthetic index was never used in the diagnosis in 91.14% of respondents; diagnostic analysis of control and diagnostic models is not carried out by 72.78%, 15.19% use cone-beam computed tomography. In the course of treatment 50.63% conduct individualization of orthodontic equipment, 63.29% perform detailed bends. The rate of orthodontic retreatment in high as 63.92% of orthodontists has the corresponding experience. Completing the treatment process only 13.29% of orthodontist perform a complete analysis of occlusal contacts. Storage of medical records is possible for up to 3 years in 31.01%, up to 5 years in 34.81% of respondents, but 78.48% reported problems with storage space in clinics. Conclusion. There are issues that require clarification in the course of continuous education which are: rendering of a computerized X-ray examination; clinical review of cases causing difficulties; identifying and determining the causes of recurrent orthodontic treatment.
