This study aimed to evaluate Class II malocclusion treatment\u2019s stability with Austro Repositioner, followed by fixed appliances, and assess its capacity to modify vertical dimensions in brachyfacial patients. A test group of 30 patients (16 boys and 14 girls, mean 11.9 years old) with Class II malocclusion due to mandibular retrognathism and brachyfacial pattern treated with Austro Repositioner and fixed appliance were compared to a matched untreated Class II control group of 30 patients (17 boys and 13 girls, mean age 11.7 years old). Lateral cephalograms were taken at T1 (initial records), T2 (end of treatment), and T3 (one year after treatment). Statistical comparisons were performed with a paired-sample t-test and two-sample t-tests. Significant improvements in the skeletal Class II relationship were observed in the treated group. The ANB angle decreased (4.75\u00b0), the SNB angle increased (3.92\u00b0), and the total mandibular length (Co-Pg) increased (8.18 mm) (p &lt; 0.001). Vertical dimensions were also significantly modified, the FMA angle increased (3.94\u00b0), LAFH-distance increased (3.15 mm), and overbite decreased (3.35 mm). These changes remained stable one year after treatment. The Austro Repositioner was adequate for treating the skeletal Class II malocclusion resulting from the mandible retrusion in brachyfacial patients.<\/jats:p>","DOI":"10.3390\/ijerph18189793","type":"journal-article","created":{"date-parts":[[2021,9,17]],"date-time":"2021-09-17T21:23:29Z","timestamp":1631913809000},"page":"9793","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Stability of Class II Malocclusion Treatment with the Austro Repositioner Followed by Fixed Appliances in Brachyfacial Patients"],"prefix":"10.3390","volume":"18","author":[{"given":"Maria Dolores","family":"Austro-Martinez","sequence":"first","affiliation":[{"name":"Department of Restorative Dentistry, School of Dentistry, CEIR Campus Mare Nostrum, University of Murcia, 30008 Murcia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6679-9431","authenticated-orcid":false,"given":"Ana I.","family":"Nicolas-Silvente","sequence":"additional","affiliation":[{"name":"Dental Pathology and Therapeutics, School of Dentistry, CEIR Campus Mare Nostrum, University of Murcia, 30008 Murcia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0228-484X","authenticated-orcid":false,"given":"Eugenio","family":"Velasco-Ortega","sequence":"additional","affiliation":[{"name":"Department of Comprehensive Dentistry for Adults and Gerodontology, University of Seville, 41009 Seville, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alvaro","family":"Jimenez-Guerra","sequence":"additional","affiliation":[{"name":"Department of Comprehensive Dentistry for Adults and Gerodontology, University of Seville, 41009 Seville, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3977-476X","authenticated-orcid":false,"given":"Jose A.","family":"Alarcon","sequence":"additional","affiliation":[{"name":"Section of Orthodontics, Faculty of Odontology, University of Granada, 18071 Granada, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,17]]},"reference":[{"key":"ref_1","first-page":"199","article-title":"Childhood and adolescent changes of skeletal relationships","volume":"68","author":"Buschang","year":"1998","journal-title":"Angle Orthod."},{"key":"ref_2","first-page":"177","article-title":"Components of class II malocclusion in children 8\u201310 years of age","volume":"51","author":"McNamara","year":"1981","journal-title":"Angle Orthod."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"142","DOI":"10.1067\/mod.2000.104489","article-title":"Class II correction in patients treated with class II elastics and with fixed functional appliances: A comparative study","volume":"118","author":"Nelson","year":"2000","journal-title":"Am.
