G-ænial Universal Flo Technical Manual

5.0 Composition

G-ænial Universal Flo has been developed with the objectives of providing a flowable material with

excellent physical properties suitable for use for all direct restorations.

In order to obtain a flowable viscosity, flowable composite resins generally exhibit a lower filler

content than putty-like composites and poorer physical properties. This is not the case with

G-ænial Universal Flo, as the formulation was developed using the following approaches:

1. Adopting new glass particles: ultra fine strontium glass. These fillers provide the following

benefits:

a. Reduced risk of filler drop-out during occlusal loading due to the small filler size (on average

200nm).

b. Combination of high radiopacity and superior translucency due to the radioapacity of the

fillers and their low refractive index.

2. A new silane surface treatment of the ultra fine strontium glass fillers. This provided in turn:

a. A higher filler load of 69%, with homogeneous dispersion of the fillers

b. Improved bonding between the particles and the matrix which together with the filler

dispersion enables the material to achieve high strength and wear resistance
