Efficacy of a Modified Lip Repositioning Surgery Technique with Tie Levator Labii Superioris and without Frenectomy and Myotomy for Treatment of Excessive Gingival Display: A Pre–Post Clinical Study

Introduction: We aimed to investigate the outcomes of a modified lip repositioning surgery technique with tie levator labii superioris and without frenectomy and myotomy for the treatment of excessive gingival display (GD). Methods: In total, 32 patients, 23 females (71.9%) and 9 males (28.1%) with excessive GD were treated with a modified lip repositioning technique. Treatment consisted of the removal of two strips of mucosa, bilaterally to the maxillary labial frenum, and coronal repositioning of the new mucosal margin. The clinical dimensions of GD, upper lip, and vermillion length were measured at baseline, 3, and 6 months postoperatively. Results: Clinical parameters, including total lip length at rest, total lip length at a smile, lip length, and GD, showed significant results ( P < 0.001) and a significant difference between baseline and 6 months postoperative ( P < 0.05). Upper lip vermillion length showed significant ( P < 0.001) but unstable results ( P = 0.43) difference between baseline and 6 months postoperative. Lip mobility showed nonsignificant outcomes ( P = 0.136). Conclusion: Treatment of excessive GD using this modified lip repositioning technique results in significant and stable outcomes regarding total lip length at rest, total lip length at smile, lip length, and GD.
