Occlusion

Occlusion refers to the blockage or obstruction of something. In various contexts, it can mean the obstruction of light, such as when one object partially covers another, or in medicine, it can refer to the blockage of blood vessels, affecting circulation. In dental terms, occlusion describes how teeth align and come together when we bite. Essentially, occlusion highlights how one element can hinder visibility or access to another, whether in the physical world or in processes within the body. Understanding occlusion helps in fields ranging from astronomy to health care.
