Abstract

The incorporation of a resilient tissue conditioner underneath the intaglio surface of the complete denture in the clinical scenario of resorbed ridges, deep bilateral undercut ridges, distorted and inflamed tissues etc enhances the retention, comfort and prevents the frequent traumatisation of the denture bearing tissues. Due to their excellent higher elastic property with addition of alcohol type plasticizers or by co-polymerization with the monomer unit, it dissipates the functional and non-functional forces and relieves the pain. Recently, the use of resilient tissue conditioner is considered as temporary, because it tends to wear, harden and discolour with time when used. Even then these resilient tissue conditioners provide cushioning effect below these dentures and provide utmost comfort to the patients. This article briefly summarizes the basic literature available on resilient tissue conditioners.
