THE NATURAL LAYERING CONCEPT AND DIRECT VENEER SYSTEM ARE THE QUINTESSENCE OF ESTHETICS FOR DIRECT COMPOSITE RESTORATIONS.
edelweiss Nano-Hybrid Composite is a light curing, radiopaque, highly filled nano-hybrid composite filling material for restorations that meet the highest standards.
For additional characterisation the edelweiss system provides following components:
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).
EDELWEISS SHADE GUIDEedelweiss dentin and enamel shades based on the natural layering technique. | EDELWEISS SHADE SELECTIONPlacing the enamel VENEER shell over the dentin core. For light refraction place glycerine within enamel shell first. |
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.
edelweiss COMPOSITE restructures teeth using two toothlike masses that are comparable to the vita dentin and enamel...
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.
Enamel shade intensifies the translucency, which increase the true opalescence for all optical variations found in natural dentition. Basic Tint: Enamel
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 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.
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.
