Abstract
Significantly more young adults had temporomandibular joint dysfunction (TMD), if there was a discrepancy of more than 1 mm between centric relation and maximum intercuspation (CR-MI).

The experimental group comprised 107 young adult patients diagnosed with TMD, about to receive orthodontic treatment. The control group was made up from 70 subjects without TMD. Psychological status was assessed using two validated questionnaires. The bimanual manipulation technique was used to identify CR, and MI was recorded using a standard method. Casts were mounted on an articulator and CR-MI discrepancies were measured. There was no difference in psychological status beween the test and control groups. If CR-MI exceeded 1 mm in the vertical or horizontal plane or 0.5 mm in the transverse plane, significantly more subjects suffered from TMD (72.9% v 11.4%, p <0.001). The authors suggest 'that CR-MI discrepancy is an important factor in the development of TMD.'
