I use a set-up wax to hold the teeth in place, then a wax-up wax to carve the setup pretty. Now I like a nice red wax for processing of immediates, I like the ease of seeing the red on the teeth when investing. The old trubyte set-up from the 60-70's held nice and teeth didn't move around then they got cheap, I've been using Barnsdent (800)252-6279 set-up since the mid 80's hold great & I even use if for baseplate rims, their wax-up carves nicely and has a pleasant color, & still go with Yates&Byrd red refined for final waxup around teeth or immediates that the patient doesn't see & it's nice for brux/TMJ/LVI appliances, nice feel & carves and stays how you carve it. & for flexible wax-up the red boils out so nice & clean. In the 70's & 80's Modern had some ethnically wax (purplish & brown) & I have a few boxes left, makes a nice presentation for darker pigmented folks. I keep my working wax in a tupperware with a scented candle (apple this mo), just like the nice smell :flowers:when I putt a sheet out, it's gone by the time I wash & shine:washing:, but it's there for me. Wax a simple thing, how do you like yours?
