    Effect of Cementation Protocol on the Marginal Adaptation of Indirect Overlay Restorations Fabricated from Two Different All-Ceramic CAD/CAM Materials
    Author(s): Zaidoon Hasan Mohammed* and Manhal A Majeed

    The objective of this in vitro study was to measure and compare the marginal adaptation of indirect overlay restorations fabricated from two different all-ceramic CAD/CAM materials (lithium disilicate and reinforced composite blocks) cemented with three different cementation protocols (adhesive resin cement, preheated composite, and sonically-activated composite). Fortyeight human maxillary first-premolar teeth were prepared for indirect overlay restorations with butt joint preparation design. The prepared teeth were divided into two main groups of twenty-four teeth each according to the type of CAD/CAM material used for the fabrication of the restorations: Group A: overlays fabricated from lithium disilicate blocks (IPS e.max CAD, Ivoclar Vivadent, Liechtenstein), Group B: overlays fabricated from reinforced resin blocks (BRILLIANT Crios, Coltene/ Whaledent AG, Switzerland).
