I have never done a wax try in with a processed baseplate. We do a type of case rather frequently it is a cast metal upper horseshoe overdenture with locator attachments. I cold cure the locator housings onto frame then wax the denture but as usual. Then during try in the flanges break off if there is too much retention. Wax is not strong enough I ivobase process. It seems silly to me to cold cure the flange on just to have to rip my wax up apart to remove the cold cure. I want the benefits of ivobase acrylic everywhere. How should I be doing this properly.
