ABSTRACT:
A dental articulator has a tooth supporting tray secured to a platform by a key and keyway wherein the sidewalls of the keyway are resiliently supported to permit yielding of the sidewalls to overcome any clogging by particulate matter which may be present in a place of use of the articulator. A set of legs upstanding from the tray maintains orientation of the tray relative to the platform.
