Nevertheless, in some cases, a more reasonable alternative may be to remove teeth with poor prognoses to improve protrusion and relieve crowding. A middle\u2010aged woman sought treatment for dental protrusion and crowding. Her mandibular right first molar had been treated with root canal therapy due to pulpitis, but she still felt uncomfortable. In addition, her maxillary left second premolar had become carious. Extractions of the maxillary right first premolar and left second premolar, as well as mandibular right first molar and left first premolar were chosen to resolve the occlusion problems. The patient opted for clear aligners on the demands of esthetics as well as comfort. Following orthodontic treatment, the patient attained properly aligned teeth, a pleasing smile, and a facial profile that exhibited greater harmony. This case report demonstrates that, under proper planning, clear aligners are capable of handling challenging cases, including those involving middle\u2010aged individuals and molar extractions.<\/jats:p>","DOI":"10.1155\/2023\/8836409","type":"journal-article","created":{"date-parts":[[2023,8,30]],"date-time":"2023-08-30T14:20:09Z","timestamp":1693405209000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Asymmetric Extraction Treatment in a Middle\u2010Aged Patient with Dental Crowding and Protrusion using Clear Aligners"],"prefix":"10.1155","volume":"2023","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-1192-222X","authenticated-orcid":false,"given":"Xiujin","family":"Xing","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-9061-6294","authenticated-orcid":false,"given":"Hanglin","family":"Qin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-3257-6768","authenticated-orcid":false,"given":"Jing","family":"Sun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4592-3960","authenticated-orcid":false,"given":"Kun","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,8,30]]},"reference":[{"key":"e_1_2_9_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajodo.2022.02.015"},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.2319\/090418-646.1"},{"key":"e_1_2_9_3_2","first-page":"459","article-title":"Treatment of severe anterior crowding with the Invisalign G6 first-premolar extraction solution","volume":"53","author":"Zhu Y.","year":"2019","journal-title":"Journal of Clinical Orthodontics"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajodo.2022.05.006"},{"key":"e_1_2_9_5_2","first-page":"639","article-title":"2017 JCO orthodontic practice study","volume":"51","author":"Keim R.
