6.0 Physical properties

6.1 Flexural strength

Definition: Flexural strength is defined as a material's ability to resist deformation under load.

and flowable composite materials. This flexural

strength test was conducted following the iSO

4049 specifications.

Within the limitations of this test, it can
be concluded that G-ænial universal
Flo shows a flexural strength similar
or superior to putty-like composites

and superior to all other flowable
composites tested.

6.2 Modulus of elasticity and fracture toughness

6.2.1 Modulus of elasticity

Definition: The modulus of elasticity (Young’s modulus) is a measure of the rigidity of the material
and is defined by the initial slope of a stress-strain curve.
a high modulus of elasticity means that the material is rigid and stiff. a material with a low modulus
of elasticity is more flexible and is better able to buffer the masticatory pressure.

and flowable composite materials. This test was

conducted according to the iSO 4049

specifications.

Within the limitations of this test, it can
be concluded that G-ænial universal
Flo exhibits higher flexibility than
conventional composites and a
similar flexibility compared to the
flowable composites
tested.
