To get the underside we went ahead and did an open tray impression as well.
We used Stiff Bite Registration as the Body and Take 1 as the wash. I adjusted his old denture as best I could so he could wear something in the interim.
The lab stripped the hybrid, added a new tooth and waxed and re-based it. Burbank did this one.
Back in the mouth, less space underneath, but still easy to clean with super floss, a proxabrush and his water pick. If this was fixed with porcelain, it would certainly be a lot harder. Unscrew the hybrid and its the lab’s job, not yours.
