Undercut Gauges

undercut gauge are used to measure the depth and the location of the undercuts on the analyzed tooth in three dimensions Stewart states the availability of undercut gauges in three

standard size namely 0.010inch , 0.015 inch and 0.020 inch Mc Cracken states the availability of undercut gauge at 0.010 , 0.020 and 0.030
