Observations on long-term use of a soft-lining material for mandibular complete dentures.

There has been ample evidence for short-term clinical success of Molloplast-b soft-lining materials, but their use has been discouraged because of an assumed need for frequent replacement. This article presents observations on 22 patients who were provided with Molloplast-b soft-lining materials in their mandibular complete dentures for up to 9 years. Fifteen of the patients were still wearing soft-lined dentures; four had been provided with implant-supported overdentures and two had converted to hard-based dentures. In nine patients occlusal wear was a reason cited for the need to replace the complete dentures, indicating that the soft-lining material had outlasted the acrylic resin teeth.
