These malocclusions often involve maxillary retrognathism, mandibular prognathism, or both, accompanied by maxillary constriction and crossbites. Comprehensive treatment should address anteroposterior, transverse, and vertical imbalances. Microimplant-assisted rapid palatal expansion (MARPE) has shown high success rates for transverse maxillary expansion in late adolescents and adults, presenting a viable alternative to surgically-assisted rapid palatal expansion (SARPE). This case report aims to demonstrate the successful treatment of a young adult female with borderline Class III malocclusion using MARPE and mandibular backward rotation (MBR) techniques. A 21-year-old female presented with a Class III skeletal pattern, anterior\/posterior crossbites, and mild dental crowding. Despite her concerns about a concave facial profile, the patient declined orthognathic surgery due to a negative experience reported by a friend. The treatment plan included MARPE to correct maxillary transverse deficiency and MBR to alleviate Class III malocclusion severity. Lower arch distalization was performed using temporary anchorage devices (TADs) on the buccal shelves, and Class II elastics were used to maintain MBR and prevent retroclination of the lower labial segment during anterior retraction. Significant transverse correction was achieved, and the severity of Class III malocclusion was reduced. The lower dentition was effectively retracted, and the application of Class II elastics helped maintain MBR. The patient\u2019s final facial profile was harmonious, with well-aligned dentition and a stable occlusal relationship. The treatment results were well-maintained after one year. The MARPE with MBR approach presents a promising alternative for treating borderline Class III cases, particularly for patients reluctant to undergo orthognathic surgery. This case report highlights the effectiveness of combining MARPE and MBR techniques in achieving stable and satisfactory outcomes in the treatment of Class III malocclusion.<\/jats:p>","DOI":"10.3390\/medicina60101588","type":"journal-article","created":{"date-parts":[[2024,9,27]],"date-time":"2024-09-27T07:49:24Z","timestamp":1727423364000},"page":"1588","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Management of Class III Malocclusion with Microimplant-Assisted Rapid Palatal Expansion (MARPE) and Mandible Backward Rotation (MBR): A Case Report"],"prefix":"10.3390","volume":"60","author":[{"given":"Heng-Ming","family":"Chang","sequence":"first","affiliation":[{"name":"Orthodontic and Dental Department, Chang Bing Show Chwan Memorial Hospital, Changhua 505, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chao-Tzu","family":"Huang","sequence":"additional","affiliation":[{"name":"Orthodontic Department, Chang Bing Show Chwan Memorial Hospital, Changhua 505, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chih-Wei","family":"Wang","sequence":"additional","affiliation":[{"name":"Orthodontic Department, Chang Bing Show Chwan Memorial Hospital, Changhua 505, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kai-Long","family":"Wang","sequence":"additional","affiliation":[{"name":"Orthodontic Department, Chang Bing Show Chwan Memorial Hospital, Changhua 505, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shun-Chu","family":"Hsieh","sequence":"additional","affiliation":[{"name":"Orthodontic Department, Chang Bing Show Chwan Memorial Hospital, Changhua 505, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kwok-Hing","family":"Ho","sequence":"additional","affiliation":[{"name":"Orthodontic Department, Chang Bing Show Chwan Memorial Hospital, Changhua 505, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu-Jung","family":"Liu","sequence":"additional","affiliation":[{"name":"Dental Department, Show Chwan Memorial Hospital, Changhua 500, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"75","DOI":"10.4236\/ojepi.2012.24012","article-title":"Prevalence of angle class III malocclusion: A systematic review and meta-analysis","volume":"2","author":"Hardy","year":"2012","journal-title":"Open J.
