Occlusal
Occlusal (pronunciation: /əˈklo͞ozəl/) is a term used in dentistry to refer to the contact between teeth. More technically, it is the relationship between the maxillary (upper) and mandibular (lower) teeth when they approach each other, as occurs during chewing or at rest.
Etymology
The term "occlusal" is derived from the Latin word "occludere", which means "to shut up" or "to close". In the context of dentistry, it refers to the closing or coming together of the upper and lower teeth.
