The influence of cement thickness on the tensile strength of two resin cements.
This study evaluated the influence of varying the cement thickness upon the tensile strength of nickel-chromium specimen cylinders cemented with Panavia Ex or Panavia 21 resin cements. A decrease in mean tensile strength of the resin-nickel-chromium alloy composite structure was recorded with an increasing cement thickness for both resin cements. Panavia 21 exhibited a significantly greater mean tensile strength than Panavia Ex at all cement thicknesses tested (P < .01).
