Locclusion

Locclusion is a term with limited and nonstandard use in scholarly and technical writing. It is not widely recognized as a distinct concept in major disciplines, and when encountered it is often a misspelling or an informal variation of occlusion rather than a defined technical term.

In established contexts, occlusion has multiple well-defined senses, such as the blockage or hiding of one object by another, occluded blood vessels in medicine, dental occlusion describing how upper and lower teeth contact, or in computer vision and graphics where objects are hidden from view by others. Because locclusion is not widely adopted in these fields, most authors interpret it as a mistaken variant of occlusion and use the standard term to avoid ambiguity.

Etymology and usage notes suggest that locclusion could be formed from a misapplied combination of “local” or “location” with the suffix in occlusion, but there is no accepted etymology or formal definition. Its appearances are sporadic, often found in drafts, informal notes, or typographical errors rather than in peer-reviewed literature. As a result, reliable communication typically relies on the conventional term occlusion, unless a specific author provides a clear, explicit definition of locclusion.
