Pre\u2010 and post\u2010treatment cephalometric radiographs and digital models were analysed to assess skeletal, dental and transverse changes. Statistical analysis was performed using parametric and non\u2010parametric tests, with significance set at\n p<\/jats:italic>\n \u2009<\u20090.05.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Both appliances improved ANB angle, Wits appraisal, overjet and overbite, with no significant intergroup differences in skeletal correction. The MA\u2010EPW group showed greater maxillary and mandibular transverse expansion and better maintenance of lower incisor inclination, whereas the TB group exhibited greater proclination of the lower incisors. The observation period was longer in the MA\u2010EPW group.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Both TB and Invisalign MA\u2010EPW appliances were effective in correcting skeletal Class II malocclusion in growing patients. The TB appliance showed greater efficiency relative to treatment duration, whereas the MA\u2010EPW appliance provided superior lower incisor control and clinically relevant transverse expansion. Further long\u2010term randomised controlled trials with defined and standardised protocols are needed to validate the clinical outcomes of mandibular advancement with clear aligners.<\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/ocr.70058","type":"journal-article","created":{"date-parts":[[2025,11,10]],"date-time":"2025-11-10T11:51:56Z","timestamp":1762775516000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Comparative Effects of Mandibular Advancement With Invisalign Enhanced Precision Wings and Twin Block Appliance on Dentofacial Structures"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9325-4063","authenticated-orcid":false,"given":"Beyza Hanc\u0131o\u011flu","family":"K\u0131rcelli","sequence":"first","affiliation":[{"name":"Department of Orthodontics, Faculty of Dentistry Bah\u00e7e\u015fehir University Istanbul Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fevzi Burak","family":"Tek","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, Faculty of Dentistry Istanbul Ayd\u0131n University Istanbul Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ebru","family":"\u00c7etinkaya\u2010Tokmak","sequence":"additional","affiliation":[{"name":"Private Practice Bursa Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G\u00f6zde","family":"\u00c7obano\u011flu","sequence":"additional","affiliation":[{"name":"Private Practice Ankara Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,11,10]]},"reference":[{"issue":"2","key":"e_1_2_12_2_1","first-page":"115","article-title":"Worldwide Prevalence of Malocclusion in the Different Stages of Dentition: A Systematic Review and Meta\u2010Analysis","volume":"21","author":"Lombardo G.","year":"2020","journal-title":"European Journal of Paediatric Dentistry: Official Journal of European Academy of Paediatric Dentistry"},{"issue":"4","key":"e_1_2_12_3_1","doi-asserted-by":"crossref","first-page":"224","DOI":"10.1053\/j.sodo.2014.09.008","article-title":"Class II Treatment With Functional Appliances: A Meta\u2010Analysis of Short\u2010Term Treatment Effects","volume":"20","author":"Vaid N.","year":"2014","journal-title":"Seminars in Orthodontics"},{"issue":"5","key":"e_1_2_12_4_1","doi-asserted-by":"crossref","first-page":"599.e1","DOI":"10.1016\/j.ajodo.2005.11.010","article-title":"Mandibular Changes Produced by Functional Appliances in Class II Malocclusion: A Systematic Review","volume":"129","author":"Cozza P.","year":"2006","journal-title":"American Journal of Orthodontics and Dentofacial Orthopedics"},{"issue":"1","key":"e_1_2_12_5_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/0889-5406(88)90188-6","article-title":"The Twin Block Technique.
