The aim of this study is to present a novel technique that combines the surgical and orthodontic approach in order to obtain the retrieval of impacted second molars through a complex distalizing movement and skeletal anchorage. Methods: Nineteen consecutive patients with impacted second molars were treated according to this technique, which involved extraction of the third molar followed by the placement of a distally positioned screw, and the subsequent use of a coil spring to connect the screw to an eyelet directly bonded on the second molar. In selected cases, it proved to be necessary to reposition the second molar through traditional orthodontics. All of the parameters were recorded: the time required for completing the treatment, the initial angle between the second molar and the adjacent tooth, and treatment related-complications. Results: Twenty impacted second molars were correctly repositioned. The mean initial angle of the second molar was 55.7\u00b0 (SD 22.6\u00b0, min 13.3\u00b0, max 104.8\u00b0). The mean treatment time was 10 months. There were no major complications. Conclusions: Given that periodontal tissues were minimally affected, the temporary anchorage device was fully controlled, and there was no unwanted movement of adjacent teeth, the presented technique not only proved effective but also minimally invasive.<\/jats:p>","DOI":"10.3390\/jcm11133565","type":"journal-article","created":{"date-parts":[[2022,6,21]],"date-time":"2022-06-21T04:39:55Z","timestamp":1655786395000},"page":"3565","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Mandibular Molar Uprighting Using Skeletal Anchorage: A Novel Approach"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2222-5764","authenticated-orcid":false,"given":"Luca","family":"Sbricoli","sequence":"first","affiliation":[{"name":"Department of Neurosciences, School of Dentistry, University of Padua, 35122 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sara","family":"Ricci","sequence":"additional","affiliation":[{"name":"Department of Neurosciences, School of Dentistry, University of Padua, 35122 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Cattozzo","sequence":"additional","affiliation":[{"name":"Department of Neurosciences, School of Dentistry, University of Padua, 35122 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7575-5799","authenticated-orcid":false,"given":"Riccardo","family":"Favero","sequence":"additional","affiliation":[{"name":"Department of Neurosciences, School of Dentistry, University of Padua, 35122 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eriberto","family":"Bressan","sequence":"additional","affiliation":[{"name":"Department of Neurosciences, School of Dentistry, University of Padua, 35122 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1916-1640","authenticated-orcid":false,"given":"Stefano","family":"Sivolella","sequence":"additional","affiliation":[{"name":"Department of Neurosciences, School of Dentistry, University of Padua, 35122 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,21]]},"reference":[{"key":"ref_1","unstructured":"Neville, B.W., Damm, D.D., Allen, C.M., and Chi, A.C.
