The effect of preparation height and luting agent on the resistance form of cemented cast crowns under load fatigue.

Statement Of Problem: The minimum amount of resistance form required for the success of a clinical crown is unknown.There is little information on the fatigue performance of complete coverage restorations on natural tooth preparations cemented with different luting cements.

Purpose: The purpose of this study was to evaluate the effect of tooth preparation height and luting agent on resistance form using unidirectional load fatigue testing.

Load-fatigue performance of gold crowns luted with resin cements.

Statement Of Problem: Resin cements have gained popularity over the past few years because of their improved physical properties. There is a need to test these cements under fatigue loading, as there is growing recognition that fatigue testing is more clinically relevant than traditional monotonic static tests.

Purpose: This study investigated the load-fatigue performance of complete gold crowns cemented with 4 types of resin cement.
