Viscoelastic Properties of Soft Lining Materials

Abstract

Viscoelastic properties of denture soft liners were measured with a torsional pendulum apparatus. Several soft acrylic and silicone materials and one natural rubber compound were studied. Available proprietary materials exhibit a wide range of elastic moduli; soft acrylic materials have high mechanical hysteresis compared with silicone materials.
