Abstract
Introduction. The shortening of clinical crown is evidenced in situations where there is gingival excess, making it a limiting factor for ideal positioning of orthodontic appliances. In these cases, preliminary surgical correction is necessary, in order to restore the dental proportions of the crowns. Laser therapy used after surgery helps tissue repair, reduces edema and postoperative pain. Objectives. This paper aims to report a clinical case of periodontal surgery (gingivectomy) associated with low-level laser therapy (LLLT), aiming at the removal of gingival excess, with functional and aesthetic purposes. Case Report. The patient, female, black, 27 years old, sought the Dental Service of the Clinic of Faculdade Adventista da Bahia, with the main complaint of gingival smile and referral for periodontal plastic surgery for further orthodontic treatment. It was decided to perform the gingivectomy of elements 15 to 25. Procedure performed in an external level, using measures of tooth proportion from the Chu Proportionality Meter. After the local anesthetic technique, the width/height ratio of the crowns was verified, followed by the measurement of the probing depth. The points were demarcated using a Williams probe and later joined with a 15C blade. The gingival contour was respected during the incision and the excised tissues were removed with McCall and Gracey curettes. The impossibility of performing osteoplasty before aligning and leveling led to a reduction in gingival thickness with the division of the flap, generating a reduction and thinning of surface. Immediately after surgery, LLLT was used, with a red laser at a dose of 1J/cm² throughout the surgical area. Final Conclusion. There was good healing and success in performing the procedure. The periodontics-orthodontics-laser therapy interaction was essential for functional and aesthetic rehabilitation.
