The three groups were compared with <sc>anova</sc> with Benjamini–Hochberg correction for multiple tests.</p> </sec> <sec id="ocr12051-sec-0004" sec-type="section"> <title>Results</title> <p>Both the Alt‐RAMEC/FM and the RME/FM protocols showed significantly favorable effects leading to correction of the Class III malocclusion. The Alt‐RAMEC/FM protocol produced a more effective advancement of the maxilla (SNA +1.2°) and greater intermaxillary changes (ANB +1.7°) vs. the RME/FM protocol. No significant differences were recorded as for mandibular skeletal changes and vertical skeletal relationships.</p> </sec> <sec id="ocr12051-sec-0005" sec-type="section"> <title>Conclusion</title> <p>The Alt‐RAMEC/FM protocol induced more favorable skeletal short‐term effects compared with RME/FM therapy in Class III growing patients.</p> </sec> </abstract>
