Abstract: 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.

Abstract: A dental cast tray subassembly for forming a dental cast model and for mounting to a dental articulator. The tray subassembly forms a channel shaped in a configuration of a human jaw to receive a mold material for forming a dental cast model. The channel further includes ribs for registering the model relative to the channel and a release mechanism for releasing the model from the channel. Further included is a platform for interconnecting with connectors for connecting the subassembly to an articulator.
