Relationship between Cervical Spine and Skeletal Class II in Subjects with and without Temporomandibular Disorders

Table 5

Absolute and percent frequencies of the craniocervical angle value for each ANB score. ANB scores are 5 to 9°/10°. Values are divided into abnormally low, normal, and abnormally high. Class II is divided on the basis of the presence or not of TMD.
