This case report details the successful management of a 28\u2010year\u2010old female patient with an objectively measured dynamic gingival exposure of 4\u2009mm. Preoperative evaluations confirmed normal clinical crown dimensions and healthy periodontal tissues, definitively ruling out altered passive eruption. The patient underwent conventional lip repositioning surgery (LRS) featuring a partial\u2010thickness mucosal excision and meticulous wound closure with 6\u20100 polytetrafluoroethylene (PTFE) sutures to mechanically restrict upper lip mobility. The dynamic gingival display decreased from 4.0\u2009mm preoperatively to 1.0\u2009mm at 2 weeks and was stably maintained at 1.5\u2009mm at the 1\u2010year follow\u2010up, meeting the treatment success criteria (\u2264\u20092\u2009mm). The procedure established a harmonious dentolabial relationship with high patient satisfaction and no complications, such as severe scarring, labial paresthesia, or relapse. These findings demonstrate that, based on accurate differential diagnosis and strict case selection, LRS serves as a safe, minimally invasive, and highly predictable intervention yielding excellent short\u2010to\u2010medium\u2010term esthetic outcomes for muscular hyperactive gummy smiles.<\/jats:p>","DOI":"10.1155\/crid\/7738188","type":"journal-article","created":{"date-parts":[[2026,7,29]],"date-time":"2026-07-29T16:55:14Z","timestamp":1785344114000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Lip Repositioning Surgery for Nonskeletal Excessive Gingival Display: A Clinical Case Report"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-9844-6531","authenticated-orcid":false,"given":"Meiya","family":"Suo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Huan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chenghong","family":"Cao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuya","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lan","family":"A.","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4646-5340","authenticated-orcid":false,"given":"Wenzhou","family":"Xu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,29]]},"reference":[{"key":"e_1_2_14_1_2","doi-asserted-by":"publisher","DOI":"10.4103\/jisp.jisp_548_25"},{"key":"e_1_2_14_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.pio.2010.04.004"},{"key":"e_1_2_14_3_2","doi-asserted-by":"publisher","DOI":"10.7759\/cureus.34032"},{"key":"e_1_2_14_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijscr.2017.11.055"},{"key":"e_1_2_14_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jobcr.2026.10"},{"key":"e_1_2_14_6_2","doi-asserted-by":"publisher","DOI":"10.1097\/SCS.0000000000007948"},{"key":"e_1_2_14_7_2","doi-asserted-by":"publisher","DOI":"10.1097\/SCS.0000000000005298"},{"key":"e_1_2_14_8_2","doi-asserted-by":"publisher","DOI":"10.21608\/EDJ.2023.193234.2437"},{"key":"e_1_2_14_9_2","doi-asserted-by":"publisher","DOI":"10.1097\/GOX.0000000000005521"},{"key":"e_1_2_14_10_2","doi-asserted-by":"publisher","DOI":"10.21608\/adjc.2025.358167.1696"},{"key":"e_1_2_14_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.coms.2021.01.005"},{"key":"e_1_2_14_12_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41415-022-4511-4"},{"key":"e_1_2_14_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajodo.2004.09.013"},{"key":"e_1_2_14_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cden.2022.02.002"}],"container-title":["Case Reports in Dentistry"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/crid\/7738188","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1155\/crid\/7738188","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/crid\/7738188","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,29]],"date-time":"2026-07-29T16:55:15Z","timestamp":1785344115000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1155\/crid\/7738188"}},"subtitle":[],"editor":[{"given":"Hannah","family":"Wesley","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"editor"}]}],"short-title":[],"issued":{"date-parts":[[2026,1]]},"references-count":14,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2026,1]]}},"alternative-id":["10.1155\/crid\/7738188"],"URL":"https:\/\/doi.org\/10.1155\/crid\/7738188","archive":["Portico"],"relation":{},"ISSN":["2090-6447","2090-6455"],"issn-type":[{"value":"2090-6447","type":"print"},{"value":"2090-6455","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,1]]},"assertion":[{"value":"2026-05-21","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-07-17","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-07-29","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"7738188"}}
