Stabilizing record bases for edentulous obturator prostheses with silicone resilient relining material

Stable record bases are critical for recording accurate maxillomandibular relations and in the evaluation of the esthetics and phonetics of wax trial prostheses. However, the record base for a maxillary obturator is often compromised because of a surgical defect and/or because the weight of the record base creates instability. This article describes a simple procedure for retaining and stabilizing a record base for an edentulous obturator prosthesis using silicone resilient relining materials.
