edelweiss Nano-Hybrid Composite is a light curing, radiopaque, highly filled nano-hybrid composite filling material for restorations that meet the highest standards.

THE SYSTEM CONSISTS OF 2 COMPONENTS

Dentin in 5 Vita Shades (A0 to A3.5)
One Enamel shade

ADDITIONAL CHARACTERISATION

For additional characterisation the edelweiss system provides following components:

NANO-HYBRID FLOWABLE COMPOSITE

in the shade Enamel

EFFECT SHADES

Effect Blue
Opaque White

INDICATIONS

edelweiss Nano-Hybrid Composite is light cured directly in the tooth cavity or on a model using any standard curing light (e.g. halogen, LED).

DIRECT APPLICATIONS

Filling of cavity classes I , I I, I II, IV, V

INDIRECT APPLICATIONS

Inlays
Onlays
Veneers

DENTIN IS SPECIALLY INDICATED FOR

Reconstruction of natural dentin

ENAMEL IS SPECIALLY INDICATED FOR

SHADE RANGE

edelweiss SHADE GUIDE

edelweiss dentin and enamel shades based on the natural layering technique.

edelweiss SHADE SELECTION

Placing the enamel VENEER shell over the dentin core.
For light refraction place glycerine within enamel shell first.

NATURAL LAYERING TECHNIQUE

The concept was proposed in 1995 by Prof. Dr. D. Dietschi and was published for the first time in 1997.
It is based on the idea of creating a synthesis between light, materialand color in order to mimic the natural tooth structure.

Shades

5 DENTIN SHADES

Single opacity - same hue, but different chroma levels - fluorescence. From Dentin A0, for the restoration of bleached teeth to Dentin A3.5, for cervical restorations of darker teeth for elderly patients. Dentin Body shades exhibit high opacity and fluorescence which correspond to natural shades of dentin.

1 ENAMEL SHADE

Enamel shade intensifies the translucency, which increase the true opalescence for all optical variations found in natural dentition. Basic Tint: Enamel

3 EFFECT SHADES

Effect Blue serves to enhance blue-opalescent effects of the incisal edge. Effect Ice helps to simulate widespread enamel opacities. Opaque White is mainly used in combination with other shades to produce “opaquers” of desired shade to cover either severely discolored tissues or metals. Tint: Effect Blue, Effect Ice, Opaque White

edelweiss SHADE SYSTEM

edelweiss VENEERs consist of the shade Enamel – Vita Enamel AO.
The respective dentin and enamel shades used to cement the VENEER
will determine the final shade tone of the restoration.

Example:
edelweiss VENEER (Vita Enamel Shade AO) cemented with Dentin Shade A3
(Vita Dentin Shade A3) will result in the Vita Dentin Shade A3.

DENTIN IS SELECTED USING THE SPECIFIC EDELWEISS DIRECT “DUAL SHADE GUIDE”.

BOTH DENTIN AND ENAMEL SAMPLES ARE COMBINED TO CONFIRM SHADE MATCH.

ENAMEL IS BUILDED FIRST USING A SILICONE INDEX MADE FROM A WAX-UP OR MOCK-UP.

THE DENTIN IS APPLIED AND MAINTAINS AN ADEQUATE SPACE FOR ENAMEL (1.2-1.4MM).

BUILD-UP IS FINALIZED WITH PROPER VOLUMES.Detailed macro and micro anatomy will be created with rotative instruments.

TECHNICAL DATA

Fillers with particle sizes in the nano meter range („nanoparticles“) show a strong tendency of aggregation and agglomeration. Therefore they do not reach their full potential for improvements of the properties of the composite (e.g. shrinkage, modulus, mechanical strength). These aggregated and agglomerated nano particles are know for a long time and are used in dental materials (Impression materials, composites) for many years. The challenge is to provide these particles in separated morphology. With the technology used in Edelweiss Composites the particles can be separated to a great extend. This is shown in the left picture. Here the nano particles can reach their full potential for improvements of shrinkage, modulus and mechanical strength.

THE TECHNICAL ASPECTS

View of a sectioned extracted human molar with a cemented prefabricated composite VENEER / OCCLUSIONVD bonded to half of the enamel surface and the other half to the dentin surface.

The most relevant observation made was obtained upon the evaluation of the inner adaptation of the restoration. No defects were visible at the interface of the enamel or in between the restorative composite and the VENEER / OCCLUSIONVD, which confirmed the excellent bond strength and stability at both interfaces (dentin/enamel to composite, composite to VENEER / OCCLUSIONVD).
