Comparison Of Solubility And Water Sorption Of Two Different Soft Lining Material.

Background: Soft denture lining materials play a very important role in Removable Prosthodontics because of their ability to provide a cushioning effect for maintaining the health of traumatized, swollen and deformed mucosa through absorption and equal redistribution of stresses over the entire area covered by denture, thus eliminating the distortion of oral mucosa. The objective of this investigation is to quantify and relate the mean solubility and water sorption of acrylic resin based permanent soft liner with a silicone based permanent soft liner.

Methods: Two different permanent soft denture liners, i.
