This clinical report describes the successful use of lip repositioning technique for the reduction of excessive gingival display. The lip repositioning technique was performed with the main objective of reducing gummy smile by limiting the retraction of elevator muscles (e.g., zygomaticus minor, levator anguli, orbicularis oris, and levator labii superioris). This technique includes removing a strip of mucosa from the maxillary buccal vestibule, 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.

Excessive gingival display (EGD), commonly known as a gummy smile (GS), is a cosmetic concern that involves exposing a significant area of gum tissue during a smile, rendering it unaesthetic. Gingival exposure greater than 3 mm is deemed aesthetically displeasing and often necessitates treatment to mask the gummy smile. The causes of EGD are multifactorial, including altered passive eruption (APE), hypermobile upper lip (HUL), short lip length, increased vertical maxillary component, gingival hyperplasia, dentoalveolar extrusion, and more.

This study presents a novel approach for maxillary advancement in a patient with cleft lip and palate, utilizing the assembly of a custom titanium implant and a ready-made distractor. The patient exhibited significant maxillary hypoplasia and had concerns regarding the possible deterioration of hypernasality after conventional surgical methods. Distraction osteogenesis was initiated to address these challenges.

In the oral cavity, the frenum is an anatomical structure composed of mucosal folds that connect the lip and cheek to the alveolar mucosa, gingiva, and underlying periosteum. An abnormally positioned maxillary labial frenum can contribute to the formation of a diastema and gingival recession. Various techniques have been proposed for the correction of aberrant frenal attachments, including frenectomy and frenal repositioning procedures.
