    Assessment of Bioactive Resin-modified Glass Ionomer Restorative as a New CAD/CAM Material Part II: Fracture Strength Study
    Author(s): Huda A Abdulla* and Manhal A. Majeed

    The objective of this in vitro study was to evaluate and compare the fracture strength of monolithic crowns fabricated from a newly-developed bioactive CAD/CAM resin block and reinforced resin CAD/CAM block with two types of resin cement (adhesive and self-adhesive cement). Bioactive CAD/CAM blocks were fabricated from ACTIVA BioACTIVE-RESTORATIVE (PULPDENT Corporation, USA). Thirty-two human maxillary first premolar teeth were prepared to receive full crowns and then divided into two main groups of 16 teeth each according to the block type that used: Group A: crowns fabricated from the bioactive resin block, Group B: crowns fabricated from reinforced composite block (BRILLIANT Crios, COLTENE). Each group was then subdivided into two subgroups according to the type of resin cement used for cementation: Subgroups (A1, B1): RelyX Ultimate cement, Subgroups (A2, B2): ACTIVA BioACTIVE-cem..
