ABSTRACT:
A methods and apparatus is disclosed herein that confirms the accuracy of dental casts. The device has four adjustable arms terminating in rests. The rests are slightly concave to receive methylmethacrylate. The arms are adjustable to mate rests with selected points or cusp tips on the model. In use, the set screw is loosened to allow a friction fit adjustment of the four arms. Once the four arms are adjusted so that the rests are aligned over desired cusp tips a locking screw is tightened. The arms are held immobilized. Methylmethacrylate is now added to the concave portion of rests. While this acrylic is still soft it is returned in the same location on model to register the imprint of the preselected cusp tips. The verifier can now be utilized to verify accuracy of another clone model by placing in similar manner on second cast. The verifier should come to rest on the second model exactly as it did on the original.
