Statement of problem After the development of a variety of ceramic restorative systems over
the past 20 years, the fabrication of fixed dental prostheses has undergone considerable …

The evolution and development of CAD/CAM systems have led to the production of
prosthetic reconstructions by going beyond the use of traditional techniques. Precision …

The purpose of this study was to evaluate the effects of both marginal fit and cementing with
different luting agents on the microleakage of all-ceramic crown systems. Thirty-six extracted …

Introduction. Discrepancy between the crown border and prepared tooth margin leads to a
microleakage that eases the penetration of microorganisms and causes the dissolution of …
