Pre-Pouring the Opposing Bases
here is the really neat part.
As you can see from the picture on the left, the upper and lower models
are not perfectly parallel to each other. By testing the relationship
between the two models prior to gluing the opposing to the already
poured base, you can make adjustments to the opposing that will improve
the esthetic value considerably.
To remedy this problem, just grind a
little more off the left bottom (patient's left) of the opposing before
gluing the lower model to the previously poured opposing base.
You can see what a little selective grinding can do for
the esthetic value.
The opposing model is now ready to be
glued to the previously poured base.
A lab in La Jolla, California showed us
this technique. If it is new to you; please give it a try. We think you
will appreciate some of the advantages.
