Bending Fracture of Different Zirconia-Based Bioceramics for Dental Applications: A Comparative Study.

ABSTRACT: The fabrication of fixed dental prostheses using aesthetic materials has become routine in today's dentistry. In the present study, three-unit full zirconia fixed prosthetic restorations obtained by computer-aided design/computer-aided manufacturing (CAD/CAM) technology were tested by bending trials. The prostheses were intended to replace the first mandibular left molar and were manufactured from four different types of zirconia bioceramics (KatanaTM Zirconia HTML and KatanaTM Zirconia STML/Kuraray Noritake Dental Inc.; NOVAZir® Fusion float® ml/NOVADENT/Dentaltechnik; and 3D PRO Zirconia/Bloomden Bioceramics). In total, sixteen samples were manufactured-four samples per zirconia material. Additionally, the morphology, grain size area distribution, and elemental composition were analyzed
