Abstract
A transparent plastic block into which jaw movement information is to be drilled is formed with a small diameter hole perpendicular to the recording surfaces of the member to serve as an index to the accuracy of the recording operation. Score lines on the recording surfaces intersecting the hole center line serve as a further accuracy guide. Score lines on the surfaces of the member facilitate observation of the information recorded in the member.
