summary In this follow‐up investigation, the ability of a new, high expansion stone to reduce acrylic resin denture base processing distortions was studied and compared with a previously reported investigation of bases processed on buff stone. Denture bases were processed by the continuous‐injection and trial‐pack techniques on flat vault palate casts and then trimmed and polished. Measurements were made at the posterior palatal border opening at 1 day and 1 week immersion in water (23°C). Results showed that denture bases processed on high expansion stone had better posterior palatal seal adaptation compared with those processed on buff stone, independent of processing techniques.
