MODERN DEFINITION Dental occlusion is the static and dynamic inter-relationships of the opposing surfaces of the maxillary and mandibular teeth that occurs during movements of the mandible and when the maxillary and mandibular dental arches are in terminal approximation.
FEATURES OF <strong>NORMAL</strong> ADULT <strong>OCCLUSION</strong> 1-The arch form varies from a parabolic to a horse-shoe shape. Lower arch is U shaped. 2-The maxillary arch occupies a greater arch of a circle than the mandibular arch hence, overbite and overjet exist between the upper and lower teeth.
