“keep your mouth open when taking an impression”…I’ve heard this. But I wonder if this is a universally applicable rule? It seems to work for some. but anatomy is finicky.
I got a very good second impression on the second try with my right mold. My mouth was closed. Nevertheless, my audi smoothed and slightly shaped that same mold in his office, and now the fit is darn near perfect. This last may bring better results than taking yet another impression and sending them off for another try at the manufacturers home base.
I wonder if luck, circumstance and who knows what else might play a role in this beyond a lot of other factors…?
