Abstract
Anterior open bite is a condition in which maxillary and mandibular incisors do not occlude at central occlusion. It is a vertical discrepancy of the jaws and dental arches that has many etiologic factors making it difficult in diagnosis, treatment and prediction of prognosis. One of the causes of open bite is abnormal size and shape of the tongue. Macroglossia, a condition in which tongue is oversized, is caused by several factors which are not clearly identifiable, and it may be a major factor of anterior and posterior open bite. Macroglossia is subdivided into true, functional and pseudomacroglossia depending on its relative size in the oral cavity. In this case report, a patient was diagnosed as skeletal Class II with pseudomacroglossia, and was treated with SARPE in order to expand the narrowed maxillary arch and quad helix for the mandibular arch. As a result the transverse deficiency was treated. In the adult patients where no skeletal growth is expected, SARPE has shown to be effective in treating maxillomandibular transverse discrepancies in which macroglossia was accompanied as in this case.
