In the literature, tongue thrust is described both as the result and the cause of open bite. If it is an adaptation to malocclusion, then tongue posture and deglutitive tongue movements should change after treatment. In this case report, an adult who had skeletal open bite and Class II malocclusion caused by mandibular retrusion was treated surgically. The mandible was advanced in a forward and upward direction with a sagittal split osteotomy. The open bite and Class II malocclusion were corrected and an increase in the posterior airway space (PAS) was observed. Pretreatment and posttreatment dynamic magnetic resonance imaging (MRI) revealed that tongue tip was retruded behind the incisors and contact of the tongue with the palate increased. It was also determined that the anterior and middle portions descended, whereas the posterior portion was elevated at all stages. Advancement of the mandible, correction of open bite, and an increase in PAS affected not only the tongue posture and deglutitive movements, but also the breathing pattern of the patient.<\/jats:p>","DOI":"10.2319\/112005-405","type":"journal-article","created":{"date-parts":[[2007,5,9]],"date-time":"2007-05-09T17:28:12Z","timestamp":1178731692000},"page":"1057-1065","source":"Crossref","is-referenced-by-count":30,"title":["Dynamic MRI Evaluation of Tongue Posture and Deglutitive Movements in a Surgically Corrected Open Bite"],"prefix":"10.2319","volume":"76","author":[{"given":"Seniz","family":"Karacay","sequence":"first","affiliation":[{"name":"aAssistant Professor, Department of Orthodontics, Dental Sciences Center, Gulhane Military Medical Academy, Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erol","family":"Akin","sequence":"first","affiliation":[{"name":"bAssistant Professor, Dental Science Center, Department of orthodontics, Gulhane Military Medical Academy, Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kerim","family":"Ortakoglu","sequence":"first","affiliation":[{"name":"cAssociate Professor, Department of Oral and Maxillofacial Surgery, Dental Sciences Center, Gulhane Military Medical Academy, Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.
