Abstract

Objective: To evaluate the effectiveness of modified lip reposition surgery in early healing and improving gummy smile. Subjects and Methods: A non-controlled pre-post clinical trial was conducted on patients aged 18 years and older with gingival exposure ≥ 3 mm at maximum smile due to upper lip hypermobility (upper lip mobility ≥ 4 mm at maximum smile). All patients underwent modified lip repositioning surgery. Periodontal parameters were assessed at baseline and 3 months postoperatively, including: swelling, pain, healing, and gingival exposure. Results and Conclusion: Within the limitations of this study, modified lip repositioning surgery improved outcomes in patients with gummy smiles due to upper lip hypermobility; and also showed early postoperative healing.
