title: Viscoelastic properties of elastomeric impression materials. I. A method of measuring shear modulus and rigidity during setting.
abstract: A method of measuring torsional shear modulus and rigidity of elastomeric impression materials has been developed and is described. In addition, the changes in viscoelastic properties of these materials during setting are discussed.
