Low-power laser as an adjunct therapy in the postoperative period of clinical crown lengthening in the aesthetic area for the correction of gummy smile: a case report

Abstract

Gummy Smile (GS) is an aesthetic condition characterized by excessive gum exposure when smiling, typically more than 2 mm. An effective technique for its treatment is Clinical Crown Lengthening (CCL) surgery, which involves procedures such as gingivectomy/gingivoplasty and osteotomy/osteoplasty. A promising adjunct therapy in the postoperative period is the use of Low-Power Laser (LPL), which contributes to inflammation control, bone regeneration, wound healing, and pain reduction. The study focuses on a clinical case of a 22-year-old patient who visited the Dental Clinic of INTA University Center - UNINTA, dissatisfied with the aesthetics of her smile due to excessive gum exposure. Examinations showed she had short clinical crowns and bulky, misaligned gums, especially in the upper incisors. CCL surgery was performed on teeth 15 to 25, and LPL was applied after the procedure and during the postoperative period. The results were positive, with the harmonization of the smile, reduced gum exposure, and increased tooth size, significantly improving the patient's self-esteem and quality of life. LPL proved to be an effective adjunct therapy, aiding in tissue recovery and contributing to the patient's emotional well-being after GS correction.
