Lip Repositioning Surgery Using an Er,Cr:YSGG Laser: A Case Series

摘要

Excessive gingival display (EGD) is a common esthetic concern. Lip repositioning surgery (LRS) was introduced as one of the treatment options to manage EGD. LRS can be used for skeletally and/or muscularly induced EGD. The present case series applied LRS using an Er,Cr:YSGG laser to treat 24 patients with minor vertical maxillary overgrowth or a hypermobile lip. At 6 months, the gingival display had decreased by 3.79 +/- 1.59 mm (mean +/- standard deviation), and the visible lip body when smiling had increased by 1.23 +/- 0.74 mm. A questionnaire revealed that the level of satisfaction with the smile increased among the patients and that they had a positive attitude toward Er,Cr:YSGG laser-assisted LRS.
