The clinical usefulness of soft denture-lining materials is well established. This laboratory-based comparative study of a heat-processed silicone (Molloplast-B) and a recently introduced fluoroelastomeric soft lining material (Novus) evaluated absorption behaviour in distilled water; the softness of the materials at different thicknesses, both dry and after immersion in water; and their compatibility with denture cleansers. A significant absorption of water, greater than 5% by weight, was displayed by Novus after 4 months' immersion. The softness of different thicknesses of Novus (up to 1.35 mm) increased significantly upon immersion over the same period when compared to Molloplast-B, which showed no change. Some surface degradation of Novus was evident upon exposure to denture cleansers that was not apparent with Molloplast-B.

    A conventional complete denture can be a successful treatment for many edentulous patients, but situations may arise, particularly in the mandible, where they do not satisfy the patient's need. The problem of denture breakage for one reason or another, is as old as the denture service itself....
