THE NATURAL LAYERING CONCEPT AND DIRECT VENEER SYSTEM ARE THE QUINTESSENCE OF ESTHETICS FOR DIRECT COMPOSITE RESTORATIONS.
Thanks to their unique laser sintering process, the translucent enamel and occlusion veneers stand out due to their inorganic, ceramic-like surface vitrification and tempered composite body. The occlusions represent the anatomic foundations for single or complete reconstructions and for increasing the vertical dimension (OVD) in the posterior region. Hence, a functioning anterior cusped guidance can also be obtained using edelweiss „VENEERs“.
edelweiss VENEERs & OCCLUSIONVD allow for minimally invasive biomechanical and economical treatment of the cause as well as prevention of cranio-mandibular dysfunction (CMD). Furthermore, malocclusion and deep bites can also be corrected minimally invasively. By covering the occlusal surfaces, usually in the mandible, the mandible is brought into the correct position for the patient in relation to the maxilla. This makes it possible to attain functioning guidance of anterior teeth and cuspids by using edelweiss VENEERs.
using edelweiss occlusal surfaces. In most cases the mandible is appropriate. It can often be identified by the great difference in height from the cuspid to the premolar (33 to 34 and 43 to 44). However, to ensure that lifting, and protrusion if necessary, is equal on the left and right, this needs to be tested using situation models on the articulator. In the premolar region this can mean capping up to 5 mm, and up to a further 3 mm in the molar region.
The maxilla and the mandible models are articulated head-adequate in habitual intercuspation. Protrusion is then performed as required and the supporting pin of the articulator raised. Michigan or Partial bite splints with “stops” are prepared for the mandibular quadrants. These are fixed temporarily in the mouth, in other words, provisionally. After a few weeks this will already represent the ideal position of the mandible, possibly requiring re-occlusion. On the basis of these bite splints the mandible is articulated anew against the maxilla.
By relining the prefabricated occlusal surfaces on existing model occlusal surfaces with composite, one can simply create a new functioning biomechanical, balanced and smoothly working masticular apparatus without irritations. Then the occlusions are transferred from the model to the patient’s occlusions and attached via bonding and composite.
For advanced professionals: Instead of lining the occlusions on the model in the articulator, a bite registration material (silicone) is used to make an occlusal impression which accurately portrays the clearance between the maxilla and the mandible in the articulator. Using the fixed silicone bite register, direct application of the prefabricated occlusion can be performed. The silicone bite register is in each case placed unilaterally (left or right) on the patient’s occlusion. In other words, when the left quadrant is restored with occlusions, the right quadrant sets the height and position of the bite elevation and thus the final position of the composite-lined and bonded occlusions on the left when biting down (replacing the supporting pin when closing the articulator). Once the left quadrant has been restored, the right quadrant is treated. Now one can optionally prepare a further silicone register from the quadrant already restored with occlusions (left) in combination with the silicone register (right) already prepared with the articulator, which additionally guides and sets the already attained occlusional relationship between the maxilla and the mandible (left) during biting. Practised users can dispense with this silicone register (for example, on the left) as the patient now already bites on the newly gained occlusion or bite elevation during biting. After setting all occlusions, re-occlusion is performed until the desired contact points have been attained.

SHAPES AND SIZES
Based on a study of all shape and size variations of natural tooth anatomy, prefabricated and contourable universal occlusion shapes for the upper and lower arches were developed.
SIZE SELECTIONThe selection of the tooth shape is made using the available sizing guide. (OCCLUSIONVD - Sizing Guide). The sizing guide is positioned over the teeth to be restored, and the outline allows for proper selection of the best-fitting occlusion.
MORPHOLOGYUltra-thin, anatomical occlusions in three sizes (S, M & L). The glass component in the composite filler and laser treatment of the surface give the material nature-like mechanical properties (biomechanics), and the material is also biocompatible (biology). Due to the natural morphology, the prefabricated edelweiss Occlusions are very easy to incorporate into an existing occlusion.
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.
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.
edelweiss VENEER (Vita Enamel Shade AO) cemented with Dentin Shade A3 (Vita Dentin Shade A3) will result in the Vita Dentin Shade A3.
