Defined as the static, closed contacting position of upper teeth to lower teeth.
Dental occlusion
Defined as a separation of teeth from occlusion; the opposite of occlusion.
Disocclusion
It should include not only a range of anatomically accepted values, but also physiologic adaptability.
Normal occlusion
