Check whether or not the patient has freedom to move the mandible back and forward with the teeth in light contact when in centric occlusion.

Temporomandibular disorders can be initiated by restorative dental treatment. One situation is for a patient to have anterior crowns placed when he or she has a very tight anterior occlusion such as seen in a patient with an Angle's class II, division II, basal bone and incisal relationship. If crowns are placed on the upper anterior teeth, which are even marginally thicker palatally than the natural teeth were, the effect is to push the mandible distally, thereby compressing the sensitive posterior bilaminar zone of the disc and producing, sometimes severe, pain.
