Properties and Procedures of Silicones for Soft Denture Bases

¹ Zoller Memorial Dental Clinic, University of Chicago, Chicago

A new and simple technique is presented for the use of silicone materials as a soft-denture-base liner that provides greater flexibility in selecting a material and technique that can best be adapted to each intraoral situation requiring the use of soft materials.

The heat-vulcanized material (Type A) was found to be most valuable where greater strength is needed, such as in obturated cases. However, the RTV adhesive material was not only considered valuable in a heat-curing technique, which provided liners for new acrylic-resin dentures, but equally valuable in the room-temperature-vulcanizing method, in which an existing denture can be relined with a soft base.

Regardless of the vulcanizing procedure employed, both of the materials appearing in Table 1 retained all the desirable properties required of a soft-denture-base material.
