The malocclusion can be associated not only with the position of the mandible in relation to the skull, but can also be associated with the cervical spine, the supra and infra hyoid structures, the shoulder girdle, thoracic and lumbar spine. In people with mesial occlusion (III skeletal class), much larger ranges of cervical vertebral anomalies such as curvature of the spine or linkage of the changed intervertebral space occur. In children diagnosed with idiopathic scoliosis, the pathology of the stomatognathic system can be observed more commonly — malocclusion, among those most commonly mentioned are distal and transverse occlusions, and asymmetrical canine and Angle classes. The greater the scoliosis, the greater the likelihood of vertical defects and increased predisposition for transverse occlusal defects. Congenital dislocation of the hip predisposes children to asymmetrical development of occlusion, most often resulting in transverse malocclusion.
