LOWER LIP SUCKING HABIT TREATED WITH A LIP BUMPER APPLIANCE

Abstract

The patient was a 12-year-old girl with a lower lip sucking habit with increased Overjet and mandibular incisor irregularity. Hyperactivity of the mentalis muscle and deepening of the labiomental sulcus because of the abnormal sucking habit was observed. Interceptive treatment was started with a lip bumper appliance to break the lower lip sucking habit. The lip bumper appliance therapy resulted in the elimination of the lower lip sucking habit, musculus mentalis hyperactivity, and labiomental strain and improvement of the lower incisor inclinations, and overjet reduction.
