Effect of light versus chemically cured resin cements on fitness of HI-ceram crowns

ABSTRACT

In this research a comparison of fitness of Hi-ceram crowns on metal dies with using two types of composite resin cement one activated by light and the other was chemically cured and then the fitness of the crowns was remeasured to get the difference. The use of light cure composite resin cement give better results as regard fitness of Hi- ceram crowns
