Effect of Recast Cobalt Chrome Base Metal Alloy on Flexural Bond Strength of Metal Ceramic Restoration.

Aim: The aim of this study was to assess and compare the outcome of recasting of CoCr alloy on the metal ceramic flexural bond strength.

Materials And Methods: 50 resin patterns were fabricated and divided into 5 equal groups and casted as: Group 1 containing 0%, Group 2 containing 20%, Group 3 containing 30%, Group 4 containing 40%, and Group 5 containing 100% recast alloy. They were layered with VITA VMK 68 porcelain powder and put through to 3-point bending test using Universal Testing Machine.
