Morphology

occlusion = occlude (semi-transparent) = occlude + sion

The noun is derived by suffixation from the verb 'occlude', but the dental technical sense (alignment/contact of the teeth) is a specialized usage that may not be obvious to all learners.

Etymology

Occlusion comes from the Latin occludere and its parts ob- 'against' and claudere 'to close', so imagine the upper and lower teeth 'closing' against each other when you bite. That's why in dentistry occlusion means how the teeth meet.
