摘要： There is disclosed a dental articulator of the Arcon type having a centric lock mechanism including a pin carried on the upper frame member and a cooperative hook arm which is pivotally mounted on the lower frame member and movable between pin engaging and detenting and pin releasing positions. The latch mechanism is spring biased to restrain the hook arm in the pin detenting position from which it can be released by pressure application to overcome the resilient bias of a compression spring loading on the mechanism. The latch mechanism is operative to lock the upper and lower frame members together when the frame members are in their closed or centric position and when the frame members are open, freely permitting rotational movement of the members between the open and closed positions while, nevertheless, retaining the frames interlocked. The articulator is also disclosed with a simple fossa guide structure allowing for a limited degree of freedom of movement without any adjustment capability and, in an alternative embodiment, with fossa guides permitting the independent adjustability of the angle of the eninentia, immediate and progressive side shifts and, optionally with an entirely adjustable fossa including adjustable top and/or rear fossa guides.

摘要： There is disclosed a calibration device for the inspection and precise setting of dental articulators which includes a stage member that is removably secured to the articulator lower frame and an scope gauge member that is removably secured to the upper frame of the articulator. A pair of position sensing indicators having sensing probes which are carried at the opposite sides of the stage member and are mechanically coupled by levers to contact points on the scope member which are located on the right and left axes of rotation of the articulator members. This permits the indicators to read, directly, relative vertical movements of the opposite sides of the articulator without being influenced by adjustments made at the opposite sides of the articulator. The inspection device includes ocular magnifiers including reticle and target indicium which cooperate to provide a vernier scale registering relative X-Y positions of the stage and gauge inspection members. The invention also includes magnetically secured dental cast and appliance mounting plates having removable magnets and metal plugs.
