RESUMO
The musculature of the lips contributes to oro-facial muscular equilibrium. Labial topography at rest is extremely variable, as there may be gaping of the lips with a short upper lip and associated protrusion of the upper alveolar process, as well as on the contrary an upwardly displaced stoma leading to incarceration of the upper dental arch by the lower lip and retrocession of the laveolar process (stoma syndrome). Anomalies at rest justify surgical treatment.
