comparison between shear bond strength of VMK master porcelain with three base-metal alloys [ni-cr-t3, verabond, super cast] and one noble alloy [x-33] in metal-ceramic restorations

ABSTRACT

Statement of Problem: The increase in the use of metal-ceramic restorations and a high prevalence of porcelain chipping entails introducing an alloy which is more compatible with porcelain and causes a stronger bond between the two. This study is to compare shear bond strength of three base-metal alloys and one noble alloy with the commonly used VMK Master Porcelain
