The aim of the study is to analyze the estimated and actual duration of treatment and the number of visits to the orthodontist by patients using modern orthodontic equipment. Analysis of the duration of orthodontic treatment of patients with varying degrees of difficulty and comparison of the estimated and actually spent time for its implementation. Material and methods. 308 medical records of patients who underwent orthodontic treatment were analyzed. According to the Siebert \u2014 Malygin method, the degree of difficulty of treatment, its duration, the number of necessary visits were calculated and the data obtained were compared with the actual time spent on correcting dental and occlusion anomalies and the number of visits by the patient to the orthodontist. Results. The results of treatment of 308 patients who underwent orthodontic treatment with modern non-removable equipment (braces) are analyzed in the clinic of LLC \u00abPrime dentistry\u00bb in Ryazan. Before starting treatment, the preliminary treatment time was calculated using the method of determining the difficulty of orthodontic treatment of Siebert \u2014 Malygin. The calculation of the degree of difficulty of treatment, its duration, and the number of necessary visits was carried out. The data obtained were compared with the actual time spent on correction of dental and occlusion anomalies and the number of visits by the patient to an orthodontist. It was found that, despite the use of modern equipment, the treatment time practically does not decrease, but the number of visits to achieve the desired result is significantly reduced. Coefficients have been calculated to clarify the required number of visits to the orthodontist. In the treatment of anomalies in the position of teeth (APD), it is 0.77, APD, combined with distal occlusion \u2014 0.79 deep \u2014 0.78, open \u2014 0.66 and mesial \u2014 0.69. Conclusion. The use of modern orthodontic equipment reduces the number of patient visits to the doctor, which saves time, reduces labor costs and allows you to provide the necessary assistance to more people in need. The coefficients calculated during the study to determine the required number of visits to an orthodontist by a patient, depending on the existing orthodontic pathology, make it possible to predict the treatment time with greater accuracy when using the Siebert \u2014 Malygin method. This is very relevant when planning upcoming manipulations and to more accurately justify the cost of treatment depending on the required time and number of visits to eliminate APS.<\/jats:p>","DOI":"10.17116\/stomat202410304154","type":"journal-article","created":{"date-parts":[[2024,8,22]],"date-time":"2024-08-22T08:36:37Z","timestamp":1724315797000},"page":"54","source":"Crossref","is-referenced-by-count":0,"title":["The duration of orthodontic treatment and the number of visits depending on the degree of difficulty when using modern orthodontic equipment"],"prefix":"10.17116","volume":"103","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2409-6345","authenticated-orcid":false,"given":"V.E.","family":"Tikhonov","sequence":"first","affiliation":[{"name":"Ryazan State Medical University","place":["Ryazan, Russia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2280-8559","authenticated-orcid":false,"given":"V.M.","family":"Grinin","sequence":"additional","affiliation":[{"name":"I.M.
