“…Therefore, it is crucial to evaluate the accuracy of DS in depicting the anticipated treatment outcomes. Previous studies have investigated the accuracy of achieving the predicted tooth movements by using clear aligners or pre-adjusted lingual appliances [ 21 – 23 ], while others have studied the arch-form prediction or the consistency in treatment plan formulation between traditional and digital methods [ 18 , 24 ]. The present study is the first to examine the accuracy of a 3D DS method that simulates the orthodontic treatment outcome produced by fixed labial appliances, using the straight-wire technique, namely the most widely used technique in daily practice.…”

Objectives To evaluate the accuracy of a semi-automatic 3D digital setup process in predicting the orthodontic treatment outcome achieved by labial fixed appliances. Subjects and Methods Twenty-five adult patients (18 to 24 years old) with class I malocclusion and moderate crowding were prospectively enrolled and received treatment on both jaws through the straight-wire technique. Prior to treatment commencement, a semi-automatic digital setup simulating the predicted treatment outcome was performed for each patient through Orthoanalyzer software (3Shape®, Copenhagen, Denmark) to obtain the prediction model. This was compared to the final outcome model through 3D superimposition methods. Metric variables and inspection of color-coded distance maps were used to detect how accurately the digital setup predicts the actual treatment outcome. Results The mean absolute distances (MAD) between the superimposed dental arches of the predicted and the final models were: 0.77 ± 0.13 mm following superimposition on the palate, 0.52 ± 0.06 mm following superimposition on the maxillary dental arch, and 0.55 ± 0.15 mm following superimposition on the mandibular dental arch. The MAD at the palatal reference area was 0.09 ± 0.04 mm. Visualization of color-coded distance maps indicated that the digital setup accurately predicted the final teeth position in a few cases. Almost half of the cases had posteriorly wider upper and lower dental arches and palatally/lingually positioned or inclined anterior teeth, whereas the rest still showed errors within 2–3 mm, distributed over the entire dental arches with no distinct pattern. Conclusions The accuracy of semi-automatic prediction of the labial fixed appliance treatment outcome in Class I cases with moderate crowding is not yet sufficient. While average measures showed deviations less than 1 mm, examination of individual color-coded distance maps revealed significant disparities between the simulated and the actual results.

“…Нехватка места в зубной дуге может возникнуть из-за нарушения сроков их прорезывания и ранней потери временных зубов. Недостаток базиса челюстей у детей наблюдается при отсутствии жевательной нагрузки [94,95,39,146]. Также сужение зубных рядов и скученность зубов в переднем отделе вызывает прорезывание третьих моляров.…”

Justification: the article describes the application of a successful technique of autotransplantation of wisdom teeth as an additional method of restoring the dentition in patients with the impending removal of the first or second molars. Objective: the goal of our work is to assess effectiveness of the technique of autotransplantation wisdom teeth instead of an extracted tooth (first or second molars). Methods: our work includes of 30 patients aged 22 to 38 years who were treated (from January 2016 to August 2022) at the Ryazan State Hospital (Department of Maxillofacial Surgery) and Prime Dentistry LLC, who underwent autotransplantation of a tooth. In our work, we evaluated the mobility of the replanted teeth, the depth of the dentoalveolar furrow, the results of the CT scans, as well as their nociceptive sensitivity. To assess the effectiveness of the technique, the Periodotest-M device, periodontal chart and photoprotocol were used. Results: the survival rate of the replanted teeth was 100% during the study. The depth of the dentoalveolar furrow reached normal values in 93% of clinical cases, mobility within normal limits - in 87% of cases. Absence of signs of ankylosis and inflammation of bone tissue in the area of transplanted teeth was observed during CT scans studies in all patients who participated in this study. Conclusion: autotransplantation of a tooth is an effective and wellpredicted operation that allows restoring the integrity of the dentition if there are indications for removal of the first or second molars.
