Fig. 1From: Effect of surface treatments on biaxial flexural strength, fatigue resistance, and fracture toughness of high versus low translucency zirconiaSchematic diagram showing the piston on three balls set-up for biaxial flexural strength testing. Zirconia discs were mounted so that the treated side was facing downwards. Specimens were then loaded to fracture using Tinius Olsen universal testing machineBack to article page
