Aim: Use of monolithic zirconia for fabrication of all-ceramic crowns eliminates several
shortcomings of layered zirconia crowns. Long-term success of restorations highly depends
on the marginal fit. The crown thickness is among the factors that affect the marginal
integrity. Meanwhile, reduced thickness of crowns has several advantages such as
preservation of tooth structure. The aim of this study was to evaluate the marginal fit of
monolithic zirconia crowns in reduced thickness and to compare the marginal fit of full …
