Gummy smile has been an esthetic concern for many patients. This clinical report describes a successful surgical coverage obtained by modified lip repositioning, thus surgically treating the gummy smile. The technique was performed to limit the retraction of elevator muscles (e.g., zygomaticus minor, orbicularis oris, leviator anguli oris and levator labi oris.) The technique is fulfilled by removing two strips of mucosa from maxillary buccal vestibule on both the sides leaving the frenum untouched and creating a partial thickness flap between mucogingival junction and upper lip musculature, and suturing the lip mucosa with mucogingival junction, resulting in a narrow vestibule and restricted muscle pull, thereby reducing gingival display. This technique is different from the conventional surgical lip repositioning as labial frenum is left untouched over here as it helps in maintain Litton the midline for lip repositioning and reduces the morbidity associated with it.
露龈笑一直是许多患者关注的美学问题。本临床报告描述了通过改良唇部重新定位获得成功的手术覆盖，从而通过手术治疗露龈笑。该技术旨在限制提肌（如颧小肌、口轮匝肌、提口角肌和提上唇肌）的收缩。该技术通过从两侧上颌颊侧前庭去除两条粘膜条，保留系带不动，并在粘膜牙龈交界处和上唇肌肉组织之间形成一个部分厚度的皮瓣，然后将唇粘膜与粘膜牙龈交界处缝合，从而形成一个狭窄的前庭并限制肌肉牵拉，进而减少牙龈外露。该技术与传统的手术唇部重新定位不同，因为此处保留唇系带不动，因为它有助于维持唇部重新定位的中线并降低与之相关的发病率。
