DIRECT VENEERs from edelweiss is state of the art for modern and minimally invasive esthetic dentistry. For the first time in the history of dental, it is now possible to work with prefabricated veneers made from nano-hybrid composite using modern laser technology. Never before has it been feasible to directly create the natural shape and youthful luminance of a tooth, so easily and perfectly in only one appointment. Its versatile area of application together with its time and cost saving procedure make edelweiss DIRECT VENEERs a sound investment in the future with the best interest of the patient in mind. Convince yourself.

Sizes

ONE SIZE FOR ALL

Based on a study of all shapes and size variations of natural tooth anatomy, prefabricated and contourable universal VENEER shapes for the upper and lower arch were developed in the following range of sizes (20 lower S/M 10 each – 30 upper S/M/L 10 each – 6 upper XS)

THE CHOICE

The choice of the tooth shape is performed with the available Sizing Guide (edelweiss VENEER Sizing Guide).
The Sizing Guide is positioned over the teeth to be restored, in which the visible profile allows for proper selection of the best fitting edelweiss VENEER. Adjustments can be illustrated directly on the template.

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.

edelweiss COMPOSITE restructures teeth using two toothlike masses that are comparable to the vita dentin and enamel…

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.

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).

FATIGUE BEHAVIOR

Fatigue behavior for composite VENEER / OCCLUSIONVD: A recent in vitro study demonstrated that prefabricated composite VENEER / OCCLUSIONVD cemented onto the enamel and dentin surface of molars, effectively resisted simulated functional fatigue and load testing. Virtually no defects were observed at both the enamel and dentin margins, either before or after loading, which typically represents the most vulnerable area of a restoration.
