Orofacial Myofunctional Therapy Effectivity in Child's Anterior Open Bite

Abstract

Background: Anterior Open Bite (AOB) is a malocclusion condition characterized by the absence of contact between the upper and lower anterior teeth, resulting from oral bad habits for a long time or abnormalities in skeletal patterns. AOB leads a lack of confidence in children because of the difficulty for lip sealing and the unclear pronunciation function. AOB occurs in children and continues into adulthood so it needs to be treated early on at the age of growth and development. One method of treating AOB is Orofacial Myofunctional Therapy (OMT) which is a method to improve the stability of the stomatognatic system by involving the exercise of the facial and neck muscles. Aim: Literature Review (LR) writing aims to find out the effectiveness of OMT in the case of AOB children, how the treatment is carried out and the problems that occur during OMT. Mini-Review: OMT increases the activity of the masseter and buccinator muscles, and decreases the contraction of the lip muscles that the lips may seal. OMT is able to increase the ability to hold the tongue to stay in contact with the palate so there is no obstacle to the eruption of the lower insisivus tooth and AOB can be corrected. Results: Orofacial Myofunctional Therapy (OMT) is effective for the correction of a child's Anterior Open Bite (AOB) as a combination therapy with the use of orthodontic tools or myofunctional equipment, especially in children older than 12 years of age and craniofacial deformity has occurred.
