Modified Technique of Gummy Smile Treatment: Double M-V Plasty for Esthetic and Functional Lip Reposition Surgery.

Excessive gingival display is a common problem that results in an unaesthetic appearance while smiling. Lip reposition surgery is a powerful, noninvasive surgery approach for gummy smile treatment, frequently performed in outpatient oral and maxillofacial surgery units. The procedure as such, provides camouflage of the increased gingival display through re-attachment of the upper lip and limits the pull effect of the muscles by reducing the depth of the upper vestibule. Few techniques of surgical treatment of maxillary gingiva overexposure have been described so far. Proposed midline double V- plasty provides anatomic reposition of the frenulum, whereas bilateral vertical M-plasty enables wider excision of the mucosa than the conventional approach providing better adaption of the wound margins without residual dog-ear defects giving more functional, esthetic, and satisfactory effect to the patients. It can also be performed in patients who do not desire orthognathic surgery with good esthetic results.
