COMPLETE DENTURES



13. RECORDS
Recording Base

You would like a recording base that fits as well as the denture. This means capturing the fold area. Thus you could use it to evaluate the future denture. However, the model is most important, so make a recording base that fits well but will not alter (abraid) the master cast when seating and removing. That means not locking acrylic into an undercut.

Impression should have been redone.

Where you have thin delicate ridges widen them with a small amount of wax so the acrylic base doesn't chip off pieces of the model.
