ABSTRACT:
A dental apparatus for use in efficiently obtaining an accurate relationship of upper and lower jaws of a dental patient which includes a wafer and a leaf gage. The wafer is made of a substantially stable but vertically deformable material and has a generally dental arcuate shape. A slot extends through the wafer for receiving the leaf gage. The leaf gage is positionable within the slot of the wafer and thereafter placed within a patient's mouth in order to obtain an accurate centric relation record.
