A step-by-step technique has been described to construct stabilized record bases which allows the dentist to take advantage of undercuts through the use of a resilient denture liner material in the undercut regions. The resilient denture liner material protects the rugae and prevents damage to the casts in the undercut regions during repeated placing and removal from the cast. Shellac denture base material at the posterior limit of the record base permits an easy method of checking the posterior palatal seal. The incorporation of the posterior palatal seal in the record base allows for adequate retention during the recording of the maxillomandibular jaw relation records and try-in procedures. The record bases made by the sprinkle-on technique are preferred to those made using the dough method. The bases are rigid, stable, not easily broken or warped, and fit accurately.
