Through a process of laser sintering and vitrification, the finished product consists of a single glass phase, embedded in a hybrid 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.

The best for your patients

“The uniqueness of edelweiss CAD/CAM BLOCKs lies in the manufacturing process where through the patented vitrification and laser sintering process a state of the art hybrid glass block is manufactured. This ensures the edelweiss CAD/CAM BLOCK combines the properties of current CAD/CAM systems into one single block. It resembles the esthetics of a feldspathic glass, the strength of particle infiltrated ceramic and the resilience and ease of reparability of composite blocks.”

“The difference lies in the high similarity with nature.”

Manufacturing process

A unique and patented manufacturing process consists of modern laser sintering and vitrification process to produce a material with outstanding physical and esthetic properties.

The end result is a homogenous hybrid glass material with high strength and long lasting shine. The bio-mechanical properties of natural tooth enamel have been reconstructed optimally, merged together with natural bio-esthetics.

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 hybrid 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 CAD/CAM BLOCK. The strength and optical properties are similar to that of ceramics but maintaining the flexibility and repairability of polymer based materials.

Indications

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.

Split-mouth clinical study – three weeks after treatment

  • Long lasting gloss can still be seen after 3 weeks.
  • There are no signs of abrasion or loss of surface anatomy.
  • Proper canine guidance can still be observed with no wear facets on the canine veneer.

  • Patient says, “The veneers on left side feel rough and is not as smooth as the right side of his mouth. It also has a dullish appearance”.

  • Patient says, “The veneers on the right side feel like his original teeth, a very smooth and polished surface”.
  • Higher magnification shows a very smooth glossy surface devoid of any surface roughness or scratches.

  • Veneer on tooth 21 chipped on incisal margin, extending to buccal side. It is a cohesive fracture occurring within the material itself.
  • Veneer on tooth 23 chipped on mesio-incisal margin. The fracture extends to buccal wall of the veneer.
  • Fractures may possibly be a result of the weakness of the material itself. The material cannot withstand occlusal forces because of its lower micro-hardness and elastic modulus values.
  • Higher magnification shows a rough surface with scratches.

Cementation of Restoration - Step by Step

1.

The attachment point of the block is smoothened out with fine-grain diamond burs. Final polish is achieved using cotton /linen buffs.

2a.

Coat the prepared fitting surface of the edelweiss restoration with edelweiss VENEER Bond using an applicator tip/microbrush and rubbing it gently. Dry edelweiss VENEER Bond using an oil and water free stream of air, so that a slightly moist layer remains on the inner surface of the edelweiss restoration without any pooling of the VENEER Bond.

2b.

Light cure edelweiss VENEER Bond for at least 20 seconds using a light curing device.

3.

An appropriate amount of the composite is softened using the finger tips, pressed into a ball and inserted into the restoration. With a spatula instrument the composite is pressed onto the inner surface of the restoration to form a thin layer of cement.

4.

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 dentin for 10–15 sec. Rinse thoroughly with water and gently dry.

5.

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.

6.

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.

7.

Cleaning and removing any excess cement from the interdental areas using dental floss.

8.

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

9.

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

10.

Work the interproximal areas with finishing strips then polish with polishing strips.

11.

Final polishing is done with a silicone cup especially around the margins of the restoration. ­This will ensure a very high gloss surface.

CAD/CAM i-BLOCK

i-BLOCK for implant solutions

edelweiss i-BLOCKs are CAD/CAM blocks used for precise and reliable fabrication of implant-supported restorations.

• biological • functional • esthetic

Precise interface integration

The edelweiss i-BLOCK can be easily integrated into the practice’s digital workflow.

Precision manufacturing pro­­­­cesses guarantee the new edelweiss i-BLOCKs fit precisely onto Titanium Base (TiBase or similar attachments).

Indications with two simple solutions

The edelweiss i-BLOCK can be used as screw retained single abutment crowns as well as for mesostructure (abutment) and final crowns.

Why edelweiss custom abutments?

  • Patient-specific soft tissue management.
  • Tissue-level cement junction compared to subgingival location.
  • Provide stability to the components, and are very easy to use.
  • The edelweiss abutment crown (TiBase + crown) can be simply screwed on to the implant.
  • The edelweiss crown and the TiBase can be assembled extraorally.
  • The edelweiss abutment is antibacterial.

Compatibility

edelweiss i-BLOCKs are compatible with systems of the providers via the TiBase interface like Dentsply Sirona, Nobel Biocare, Straumann, etc.

Patient case i-BLOCK

For optimum esthetics, the edelweiss i-BLOCK was first milled as a mesostructure and cemented to the implant abutment. The final crown was milled with edelweiss C-BLOCK A2. This ensured a perfect esthetically driven emergence profile and a biologically driven mucosal seal.
