Posselt

Posselt is a surname of German origin. It is found in Germany, Austria, and among communities of German descent around the world. As with many German names, its exact meaning is not always clear without local genealogical context; it is probably either toponymic, referring to a place, or patronymic, derived from a given name.

In dentistry, Posselt's envelope of motion, also known as Posselt's border movements, describes the theoretical outer boundary of the mandible’s movements. It maps functional and border movements of the jaw, including protrusive, retrusive, and lateral excursions, and is used in occlusal analysis, denture fabrication, and orthodontic planning.

Beyond dentistry, Posselt is a surname borne by individuals in various professions. In reference works, the name appears in genealogical and biographical contexts as part of the broader catalog of Germanic surnames. The spelling is retained in historical records and contemporary documents alike.
