Denture soft linings: materials available

Denture soft lining materials are products which are applied to the fitting surfaces of dentures for the purpose of achieving a more equal distribution of load and reduction of local point pressures. These materials have provided a focus for research and controversy for over 100 years. In that time large numbers of products have been advanced as the ideal soft denture liner. This paper discusses the five main groups of materials that have been available to dentists: the natural rubbers, vinyl co-polymers, hydrophilic polymers and the silicone and acrylic based soft lining materials.
