The Relationship Between Lip Augmentation and Teeth Visibility: A Cosmetic Perspective.

Objectives: This paper aims to describe the ideal relationship between lips and teeth as 2 critical facial features to guide young doctors keen on lip augmentation.

Methods: The literature survey was performed in PubMed, EBSCO, UpToDate, Proquest Central databases of Kirikkale University, and Google and Google Scholar databases.

Results: There is a relationship between the visibility of teeth and the amount of tooth show and its attractiveness, but only if the gingival exposure is within the standard setting and between the upper central incisor tips if the buccal corridor is not exceeding 1 mm. A smile's visual expression and aesthetics do not simply involve the lips alone. Facial esthetics result from harmony between several minor factors, the combination of which determines the patient's overall appearance. For instance, when laughing with an open mouth, a person's teeth become visible. The need for lip enhancement is based on the patient's aesthetic goals, infrastructural tooth position/visibility, and stage of facial aging. To help achieve lip augmentation goals, facial aesthetic subunits, soft-tissue patterns, and bony landmarks should be considered. Lip augmentation is typically performed by adding volume through various means and materials.

Conclusions: The authors must offer essential new data on the relationship between lip augmentation and teeth visibility. A given upper lip enhancement will make the maxillary incisors visible to a greater or lesser extent. However, there is limited research on what constitutes a prioritized single most crucial factor in promoting maxillary incisor visibility.
