ABSTRACT:
A dental articulator has a generally horizontal base, one end of which acts as the lower bow. Projecting upwardly from this base is a stem. Mounted on the top of the stem by a slip-on construction is a removable hinge support. The hinge support has a pair of spaced vertical flanges, each of which has an elongated slot inclined to the horizontal at an angle approximating the angle between the jaws that the human condyles make upon forward and rearward motion. An upper bow is hinged to the flanges by a hinge pin passing through the elongated slots. Elastic bands engage both ends of the pin and the hinge support to normally keep the pin in the lower end of each slot. The bands are resilient enough to allow the operator to pull the upper bow backwardly along the condyle angle to check the teeth for forward and backward clearances and also to allow the operator to twist the upper bow with respect to the lower bow to check for clearances upon lateral movement of the teeth.
