Compendium of Continuing Education in Dentistry (Jamesburg, N.J.: 1995), 42(9), 516–519.https://hdl.handle.net/1805/33826Esthetic crown lengthening is a periodontal surgical procedure to correct excess gingival display (ie, "gummy smile"). The procedure may require soft-tissue excision only, osseous resection, or a combination of both. However, the long-term healing responses, such as soft-tissue relapse or recession and hard-tissue regrowth and resorption, have not been fully reported in the literature. This case report describes the management of a patient with esthetic concerns about a gummy smile. The patient stated that the maxillary anterior area had been previously treated with periodontal surgery 7 years earlier but the condition had slowly recurred over time. The authors highlight the possible reasons for the recurrence and the keys to successfully managing the case.en-USPublisher PolicyEsthetic crown lengthening (ECL)periodontal surgical proceduregingival displayArticle
