In order to test the null hypothesis "there is no association between malocclusion and postural alterations in head and neck" a non-experimental analytical study was carried out in patients with clinical orthodontic treatment. The sample consisted of 116 patients with malocclusion treated at the Specialization Program in Orthodontics and Dento Maxillo Facial Orthopedics from 2007 to 2009, Faculty of Dentistry, Universidad de Chile. We analyzed the records of each patient, for search partnership between the values of Cervical Skull Rocabado Analysis, the cephalogram and study models. We found weak statistical associations between anti-rotation time of the cranium (skull, vertebral angle and distance diminished intervertebral C0-C1), with skeletal class III also had mandibular posterior rotation and were dolicho facial. High values of the hyoid triangle, were weakly associated with skeletal Class II, along with changes in tongue position at rest and dental retrusion. We conclude that in patients with malocclusion there is a statistically weak association with altered craniocervical posture.
