This device is used to measure tooth width vs height. Though the lines do not represent true Gold Proportions, it is generally accepted. The goal is to match length and width at corresponding notches or nobs.

This is designed to be 3D printable in it’s entirety, though supports are needed. I print it horizontally on it’s back. After processing and supports are removed, an appropriate intraoral marking device can be used to mark the nobs. You should be able to simply swipe your marker or paint across as the notches should remain unmarked.

The markings are as listed below:

Width: 5.5, 6.5, 7.5, 8.5, 9.5, 10.5mm
Length: 7, 8.5, 9, 10.5, 11.5, 13mm
