Place a transparency on top of your impression and use a permanent marker to trace the dental pattern onto the transparency as accurately as possible.
Now unbend the plate and measure the width and depth of the impressions from both jaws. Also note any unique characteristics such as slanted teeth, spaces, evidence of braces, etc. Record this data below.
Write your name on your plate and place it at the front of the room.
The dental pattern of 6 different maxillae has been traced for you on a separate sheet; they are labeled A-F. Measure the width of each maxilla and note any unique characteristics in the table below.
7 different dental mold mandibles are located around the room, 6 of these match the maxilla tracings on the separate sheet. Using the tracings of the maxillae attempt to match the upper jaw with the lower jaw labeled 1-6. The lower teeth should fit into the arch of the upper teeth. For most people, the upper teeth will extend beyond the lower teeth.
