edelweiss dentistry presents a breakthrough in the fabrication of CAD/CAM materials. Through a process of laser sintering and vitrification the finished product consists of a single glass-phase embedded in a resin matrix.

As a result, the esthetic properties are similar to that of feldspathic glass ceramic without having the brittleness of pure ceramics. The strength and optical properties are similar to that of ceramics but maintaining the flexibility and repairability of polymer based materials.

Note: This product is available and approved exclusively for dental customer groups.

Visual Comparison

edelweiss CAD/CAM Block exhibits natural translucency, with light reflection showing an extremely glossy surface.

The edelweiss blocks are more translucent than other blocks giving a more natural appearance which may be attributed to the aluminium oxide and barium silicate glass.

The technology behind the CAD/CAM Blocks

Breakthrough in CAD/CAM Materials

edelweiss dentistry presents a breakthrough in the fabrication of CAD/CAM materials. Through a process of laser sintering and vitrification, edelweiss has developed state of the art CAD/CAM blocks. Through this process, the finished product consists of a single glass-phase embedded in a resin matrix. As a result, the esthetic properties are similar to that of feldspathic glass ceramic without having the brittleness of pure ceramics.

Silica and Barium Glass as a Base

The base material of the edelweiss block is glass, in which crystals are joined by controlled laser sintering. The edelweiss CAD/CAM block is mainly composed of silica and barium glass with a very small portion of resin, almost combining the added advantages of ceramic and polymer materials into one block.

Strong but Flexible

The addition of zinc oxide nanoparticles and fluoride provides antibacterial properties, a unique feature of the edelweiss block. The strength and optical properties are similar to that of ceramics but maintaining the flexibility and repairability of polymer based materials.

edelweiss CAD/CAM Blocks - A Unique Fusion

Interview with Dr. Desigar Moodley, Office visit with Dr. Alessandro Devigus (Bülach, CH) with following Case Study

Elemental Analysis

The composition of edelweiss CAD/CAM Blocks are mainly barium/silicate glass, zinc oxide nanoparticles, aluminium oxide and fluoride.

Barium silicate glass ensures adequate bonding to the tooth structure using the edelweiss bonding system.

The addition of zinc oxide nanoparticles provides antibacterial properties preventing any plaque accumulation on the surface of the material.

Fluoride enables possible hydroxyapatite regeneration if required. The addition of ZnO and F- is unique to the edelweiss CAD/CAM Blocks.

Aluminium oxide provides additional strength and improves the optical properties of the CAD/CAM block.

SEM Analysis

edelweiss CAD/CAM Block

The edelweiss CAD/CAM Block shows a complete homogenous fusion of glass particles to form a single phase unit. There is a complete absence of voids or defects on the surface structure. (Mag= 3.00KX)

Manufacturer B

The SEM of the Manufacturer B CAD/CAM Block shows an inhomogenous surface structure possibly due to it being a composite/ceramic hybrid. Several voids and cracks appear on the surface. (Mag= 2.83KX)

Conclusion

SEM show the compactness in the structure of the edelweiss CAD/CAM Blocks. This ensures minimal chances of crack propagation under normal occlusal forces.

The geometry of the glass crystals within the material is similar to natural enamel enabling proper light scattering for optimal esthetics.

Optical properties of edelweiss CAD/CAM Blocks show superior esthetic properties due to the pure glass structure and aluminium oxide.

edelweiss CAD/CAM Blocks come with the added advantage of the inclusion of zinc oxide and fluoride making it antibacterial.

Step by Step / Cementation of Restoration

1.

Apply 37% phosphoric acid gel to the prepared tooth. The etchant should be left to react on the enamel for 15–30 sec. and on the dentine for 10–15 sec. Rinse thoroughly with water and gently dry with compressed air.

2.

Starting with the enamel, thoroughly coat the tooth surfaces to be treated with Dentine Bonding Agent/Adhesive. The adhesive must be gently applied to the tooth surface for at least 20 sec. and light cured for 20. sec in all directions.

3.

After placing an appropriate amount of the composite cement into the restoration, gently seat the restoration onto the prepared tooth surface and retain it in place exerting uniform pressure. Remove all excess composite material

4.

Cleaning of interdental area with dental floss.

5.

Final light-cure for 20 sec. on all surfaces and margins with a curing unit with light intensity of 1000 mW/cm2

6.

After having adhesively cemented the restoration, adjust occlusion/ articulation with suitable grinding instruments.

7.

Work the interproximal areas with finger-strips then polish with polishstrips. Polish the cervical areas with silicone-polishing cup. Final polishing is done with a silicone disk and polishing brushes.
