G-ænial Universal Flo Technical Manual

6.0 Physical properties

6.1 Flexural strength

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

Figure 4: Flexural Strength of various composite

and flowable composite materials. This flexural

strength test was conducted following the ISO

4049 specifications.

Amsterdam, 2011

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.
