Definition
the closing or blocking of something
The exact meaning of occlude can depend upon its context. For example:
  • "an occluded artery" — closed or blocked, so no blood can flow through it
  • "occluded teeth" — position when the jaw is closed
  • "an occluded front" — when warm air is separated/blocked from the ground after meeting a cold front
  • "an occluded graphic" — a graphic that cannot be seen because it is blocked by an image between it and the eye


In dentistry, malocclusion is the misalignment of teeth and jaws. (mal- being a common prefix for bad.)
  • Doc Daneeka would never go swimming again; a person could swoon or suffer a mild coronary occlusion in an inch or two of water and drown to death, be carried out to sea by an undertow, or made vulnerable to poliomyelitis or meningococcus infection through chilling or over-exertion.
