Disposable dental articulator

摘要

A dental model and articulator system comprises upper and lower dental casts that each receive a corresponding anchor in their respective vertical posterior faces. A generally rectangular articulator main body has a transverse horizontal hinge attachment on its top that connects to an upper arm and the anchor on the upper dental cast. A vertical pivot is provided in the bottom end of the articulator main body that connects to the anchor on the lower dental cast. The upper and lower anchors attach to their respective articulator parts with a stem-in-sleeve arrangement that allows independent lateral tilting of both the upper and lower dental casts for occlusal and masticatory registration and fixing with glue. The vertical pivot also attaches to the articulator main body with a stem-in-sleeve arrangement that allows further degrees of freedom for the occlusal and masticatory registration between the upper and lower dental casts and for fixing the registration with glue. The anchors are secured to their respective dental casts by either gluing the anchor to a slot in the dental cast or by casting the anchor in the dental cast during the molding process.
