Abstract

One of the most difficult malocclusions to diagnose and treat is Class III malocclusion. It is characterized by an alteration in the sagittal relationship of the jaws, either by a deficiency or maxillary retrusion or mandibular prognathism, or whether a combination of the above. The etiology is multifactorial and is due to an interaction of hereditary and environmental factors.\nA 4-year-old female with hereditary pattern of class III malocclusion in his mother s family is presented. Skeletal Class III, increased jaw length, protruded, rotating posterior and maxilla retruded. Vertical growth type, straight profile, anterior crossbite and posterior left-sided. Orthopedic appliance therapy was instituted during the deciduous dentition to the permanent dentition, to achieve , balancing the maxillomandibular growth. One of the most complex aspects of orthopedic clinical management of Class III malocclusion is the possibility of relapse after active treatment period, however, in our patient changes in skeletal, dental and aesthetic aspects achieved during treatment have been stable.
