REFER TO YOUR SYLLABUSBut remember:1. That you establish the
tilt which is usually a compromise between guide planes
and undercuts so you will evaluate various tilt locations with
guide planes andundercut areas in mind.
2. Guide planes and height of contours (undercut areas) are all
relative to your tilt.3. When marking height of contours on teeth
keep the lead tip at the gingivae to avoid
marking a false height of contour.4. To use the undercut gauge
with the single strip = .015. Have all survey lines marked on your
cast before picking up red pencil to draw
your design.6. You cannot use the tilt on one cast to establish
the tilt on a second cast of the same
arch as the bases will not be the same in relation to the
teeth.
