Several aspects must be considered, such as periodontal health, orthodontic mechanics, functional and esthetic alterations, and treatment stability. Despite controversies, extraction of teeth to solve dental crowding is a therapy that has been used for decades. Premolar extractions are the most common, but there are situations in which atypical extractions facilitate mechanics, preserve periodontal health and favor maintenance of the facial profile, which tends to unfavorably change due to facial changes with age. The extraction of a lower incisor, in selected cases, is an effective approach, and literature describes greater post-treatment stability when compared with premolar extractions. This article reports the clinical case of a patient with Angle Class I malocclusion and upper and lower anterior crowding, a balanced face and harmonious facial profile. The presence of gingival and bone recession limited large orthodontic movements. The molars and premolars were well occluded, and the discrepancy was mainly concentrated in the anterior region of the lower dental arch. The extraction of a lower incisor in the most ectopic position and with compromised periodontium, associated with interproximal stripping in the upper and lower arches, was the alternative of choice for this treatment, which restored function, providing improved periodontal health, maintained facial esthetics and allowed finishing with a stable and balanced occlusion. This case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO), as part of the requirements for obtaining the BBO Diplomate title.<\/jats:p>","DOI":"10.1590\/s2176-94512013000300024","type":"journal-article","created":{"date-parts":[[2013,11,2]],"date-time":"2013-11-02T10:32:05Z","timestamp":1383388325000},"page":"150-158","source":"Crossref","is-referenced-by-count":5,"title":["Angle Class I malocclusion treated with lower incisor extraction"],"prefix":"10.1590","volume":"18","author":[{"given":"Vanessa Leal Tavares","family":"Barbosa","sequence":"first","affiliation":[{"name":"State University of Rio de Janeiro"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"issue":"5","key":"ref1","doi-asserted-by":"crossref","first-page":"560","DOI":"10.1016\/0002-9416(77)90024-0","article-title":"Lower incisor extraction in orthodontic treatment","volume":"72","author":"Bahreman AA","year":"1977","journal-title":"Am J Orthod","ISSN":"http:\/\/id.crossref.org\/issn\/0002-9416","issn-type":"print"},{"issue":"6","key":"ref2","doi-asserted-by":"crossref","first-page":"546","DOI":"10.1016\/0889-5406(92)70072-I","article-title":"Edward H: Angle versus Calvin S.
