[Somatic dysfunctions of the cervical spine and fixed orthodontic treatment: a 145 subjects-cross sectional study].

 Cervical disorders should not be attributed to long-term multi-attachment treatment since once the active orthodontic treatment is finished, the SD are not significantly increased compared to the control group. These results may encourage to make a study to evaluate benefits of cervical osteopathic follow-up for patients at risk after the setting of the fixed appliance.
