A six-year retrospective study of Molloplast-B-lined dentures. Part II: Liner serviceability.

A 6-year retrospective investigation was conducted into the serviceability of Molloplast-B-lined dentures with the following results: The Molloplast-B-lined denture is not a temporary expedient but can remain serviceable for a time competitive with that of conventional acrylic resin dentures. All the soft liners were still serviceable after 4 years and 83% after 6 years. The longevity of the soft liner is dependent on correct processing procedures and proper home care. The three liners judged as unserviceable exhibited excessive wrinkling, and all had been soaked in a bleach-type cleanser. The resilience of the liner is dependent on its thickness. The optimum thickness is approximately 3 mm. The resilience of the liner did not decrease with time. No noticeable wear of the soft liner was observed. Staining was present in about half the soft liners. Smoking was commonly associated with staining and odor of the soft liner.
