Several cross-sectional studies have shown the association of a dysfunctional orofacial environment with a greater prevalence of malocclusions. Orofacial myofunctional reeducation (OFMR) is the rehabilitation of the muscles, functions and resting postures of the orofacial complex. It is used in the therapeutic management of orofacial dysfunction in patients of all ages and with a wide range of disorders and comorbidities. RMOF mainly uses isotonic and isometric exercises targeting the oral and oropharyngeal structures, combined with specific exercises for ventilation, swallowing and mastication. It may involve the use of prefabricated reeducation appliances (PRAs), which may also be prescribed to modify the shape and relationship of the dental arches.
