One important criterion for the long success of all-ceramic crowns is theremarginal fit. The margin of a restoration is the interface between a restorative material and thetooth, and it is vital to the long-term success of the restoration. If marginal discrepancies arepresent, the luting material will be exposed to the oral environment, thus leading to a moreaggressive rate or cement dissolution. As a result, the cement seal becomes weak and allows thepercolation of bacteria.
