Compressive and Diametral Tensile Strength of ACTIVA BioACTIVE-RESTORATIVE is comparable to composites and far superior to glass ionomers and RMGIs.
Volume wear of ACTIVA BioACTIVE-RESTORATIVE is comparable to composites and far less than glass ionomer. When evaluated for surface wear resistance, ACTIVA BioACTIVE-RESTORATIVE performed better than all other materials tested with abrasive toothpaste and was comparable to flowable composites with non-abrasive toothpaste.
ACTIVA’s rubberized resin component provides unparalleled toughness and resilience. Toughness, measured by deflection at break using a 3-point bend test, is the ability of a strong, hard material to absorb stress, dissipate forces and resist fracture when a load is applied.
Fatigue limit is determined by the incremental load required to cause fracture within a defined number of cycles. Deflection at Break of ACTIVA is 2-3 times greater than composites and 5-10 times greater than GIs and RMGIs.
Flexural strength and flexural fatigue measure the amount of stress a material can withstand, measured by deflection at break, and its endurance, measured by the number of repeated cycles before failure. ACTIVA meets the requirement of ISO 4049 for occlusal restorations and demonstrates flexural strength and flexural fatigue comparable to flowable composites (FC) and significantly greater than conventional RMGIs and GIs tested.
