Abstract
A visible light-cured reline resin presently marketed is used directly in the mouth to record the tissue. The viscosity of the material will therefore have an effect on the success of the reline. This article compares the viscoelastic properties of the currently marketed visible light-cured material with a medium-body rubber base material. A cone and plate viscometer was used to help derive the apparent viscosity and flow index of the materials. Readings were recorded with varying shear rates at 25 degrees C and 37 degrees C. The visible light-cured resin was found to have a higher apparent viscosity and flow index than the medium-body rubber base at low shear rates. Temperature had an indirect relationship with the viscosity.
