abnormal occlusion  malocclusion.

balanced occlusion  occlusion in which the teeth are in harmonious working relation.

centric occlusion  that in the vertical and horizontal position of the mandible in which the cusps of the mandibular and maxillary teeth interdigitate maximally.

coronary occlusion  complete obstruction of an artery of the heart.

eccentric occlusion  occlusion of the teeth when the lower jaw has moved from the centric position.

habitual occlusion  the consistent relationship of the teeth in the maxilla to those of the mandible when the teeth in both jaws are brought into maximum contact.

lateral occlusion  occlusion of the teeth when the lower jaw is moved to the right or left of centric occlusion.

lingual occlusion  malocclusion in which the tooth is lingual to the line of the normal dental arch.

mesial occlusion  the position of a lower tooth when it is mesial to its opposite number in the maxilla.

normal occlusion  the contact of the upper and lower teeth in the centric relationship.

protrusive occlusion  anteroclusion.

retrusive occlusion  distoclusion.

venous occlusion  the blocking of venous return.
