Relationship between cervical spine and skeletal class II in subjects with and without temporomandibular disorders
AIM. To assess changes of cranio-cervical structure and of hyoid bone position in skeletal Class II subjects with and without Temporomandibular disorders (TMD). MATERIAL AND METHODS. The cephalometric analysis of 59 subjects with skeletal Class II were evaluated and compared. The measurements considerated were: ANB as parameter of Class II and C0-C1 distance, C1-C2 distance, cranio-cervical angle and hyoid bone position for the cervical spine analysis. Patients were divided into two subgroups: patients with TMD (group A) and patients without TMD (group B).
