In studying the anterior (front) teeth we got a chance to carve, with all the correct dimensions, the right maxillary central incisor - this was pretty fun but time consuming.
Here's what I did:
I first had to get my tools together: wax, boley gauge, carving knife and a sheet of paper to reduce the mess. I then had to use the boley gauge to mark my dimensions on the wax, after which I drew an outline of the tooth.
Dimensions:
Maxillary Central Incisor | Length Crown | Length Root | Mesiodistal Crown | Mesiodistal Cervix | Bucco-lingial Diameter | Bucco-lingual Cervix | Mesial cervix/Distal cervix |
(mm) | 10.5 | 13.0 | 8.5 | 7.0 | 7.0 | 6.0 | 3.5/2.5 |
from left: boley gauge, block of wax with dimensions and outline of tooth drawn, carving knife. |
After that was done it was time to get to carving! The wax was pretty hard, I had to use the carving knife to shave down to the outline that was drawn on the wax.
wax shaved down towards the outline drawn |
The aim of this part was to get as close as possible to the outline made, so I had to carve some more.
Proximal/side view: wax carved to the outline drawn |
Facial/front view: wax carved to the outline drawn |
After the carving to the outline was done it was time to put everything learned in Occlusion class to work! Generally speaking, the mesial surface should be angled acutely, the distal surface more round, cervical line at mesial surface should be lower than on the distal surface,the root should taper distally (how's that for mumbo-jumbo??)
So after carefully carving and measuring and carving and measuring some more I finally had what looked like the right maxillary central incisor with the correct dimensions.

Carving the tooth was a fun exercise though time consuming. The images above are far from perfect but was my first of two trials. The second was a little better but I took no pictures of those.
