RESUMO
Patients with malocclusions frequently function normally and retain their dentition without problems. Strong correlations between occlusal factors and mandibular dysfunction are still controversial. However, signs and symptoms of craniomandibular disorders appear to be prevalent in children as well as in adults. Almost no symptoms of dysfunction have been seen in children aged 3-6 year. Work in the developmental aspects of these disorders has to be done. Orthodontic therapy seems unable to prevent CMD or resolve these problems. Generally, it does not cause or predispose people to develop CMD. If painful symptoms arise during treatment, it may be necessary to modify active treatment. Occlusal equilibration must be carried out with very much caution.
