Overview: The load-bearing capacity of traditional CAD-CAM fabricated dental prostheses was significantly increased through the formulation of novel blocks incorporating dimethacrylate resins and silanated glass from Esstech Inc.

Objectives: To compare handmade and computer-aided design–computer-aided manufacturing (CAD-CAM)-fabricated fixed dental prostheses (FDPs) composed of a particulate filler composite.

Materials and Methods: Handmade FDPs were made of restorative composite (Z 100) and CAD-CAM-fabricated FDPs were made of commercial CAD-CAM blocks (VITA Temp) and two experimental CAD-CAM blocks of particulate filler composite. Experimental CAD composite A was prepared by mixing 31.2 wt.% of dimethacrylate resin with 68.7 wt.% of filler particles of barium oxide silicate (BaSiO2). Experimental CAD composite B was prepared by mixing 25.6 wt.% of dimethacrylate resin with 74.3 wt.% of filler particles of BaSiO2. Six groups were fabricated (n == 6 in each); FDPs were statically loaded until final fracture.

Results: Experimental CAD composites A and B revealed the highest load-bearing capacity of the FDPs, while Z 100 showed the lowest.

Conclusion: FDPs made of experimental CAD composite blocks showed higher load-bearing capacities than handmade commercial composites and commercial blocks.
