The present case report describes an interceptive treatment on a 4-year-old girl with a unilateral scissor bite combined with an anterior crossbite, increased reverse overjet, and overbite on a skeletal Class III base. The patient was treated with a new Prefabricated Functional Appliance (PFA) which was modified from a Frankel-III appliance to induce a mandible to move backwards and relieve an occlusion discrepancy of the dental arch, and a functional dental rehabilitation with resin and myofunctional exercises with a PFA which was modified from an oral screen appliance were performed during the treatment. The total treatment time was 11 months and a satisfactory improvement of occlusion and facial esthetics was achieved. This case report presents a new PFA system and treatment protocol in primary dentition which results in a favorable outcome, and the clinical effectiveness of this appliance system warrants further investigation.<\/jats:p>","DOI":"10.3390\/children8110957","type":"journal-article","created":{"date-parts":[[2021,10,24]],"date-time":"2021-10-24T22:06:16Z","timestamp":1635113176000},"page":"957","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Unilateral Scissor Bite Managed with Prefabricated Functional Appliances in Primary Dentition\u2014A New Interceptive Orthodontic Protocol"],"prefix":"10.3390","volume":"8","author":[{"given":"Chaypat","family":"Simsuchin","sequence":"first","affiliation":[{"name":"Postgraduate Certificate in Orthodontics, Director of Ortho-Kids Club, Chiang Mai 50200, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8337-4873","authenticated-orcid":false,"given":"Yong","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Stomatology, School of Medicine, Xiamen University, Xiamen 361005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuying","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Stomatology, School of Medicine, Xiamen University, Xiamen 361005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9432-2590","authenticated-orcid":false,"given":"Sreekanth Kumar","family":"Mallineni","sequence":"additional","affiliation":[{"name":"Department of Preventive Dental Science, College of Dentistry, Majmaah University, Al-Majmaah 11952, Saudi Arabia"},{"name":"Department of Pediatric and Preventive Dentistry, Saveetha Dental College and Hospital, Saveetha Institute of Medical and Technical Sciences, Saveetha University, Chennai 600077, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhihe","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, West China School of Stomatology, Sichuan University, Sichuan 610017, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Urban","family":"Hagg","sequence":"additional","affiliation":[{"name":"Discipline of Orthodontics, Faculty of Dentistry, The University of Hong Kong, Hong Kong 999077, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Colman","family":"McGrath","sequence":"additional","affiliation":[{"name":"Discipline of Dental Public Health, Faculty of Dentistry, The University of Hong Kong, Hong Kong 999077, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"151","DOI":"10.1016\/j.jegh.2014.07.001","article-title":"Occlusal characteristics and prevalence of associated dental anomalies in the primary dentition","volume":"5","author":"Lochib","year":"2014","journal-title":"J.
