edelweiss PEDIATRIC CROWNs are laser-sintered, pre-polymerized, highly filled enamel shells made of nano-hybrid composite. Their anatomical profiles guarantee faithful and at the same time highly esthetic replicas of natural deciduous teeth. Thanks to improved physical properties, they can be used directly as single crowns for anterior and posterior deciduous teeth.


edelweiss PEDIATRIC CROWNs are prefabricated, radiopaque PEDIATRIC CROWNs that replicate the anatomical base of the enamel layer of the tooth. Together with edelweiss COMPOSITE, they can be used to fabricate simple or complex restorations of deciduous teeth in both the anterior and posterior regions in cases of superficial or deep caries. PEDIATRIC CROWNs protect the deciduous tooth until natural exfoliation (tooth loss) while providing functional support by maintaining proper occlusal contacts with opposing teeth. Occlusion can be easily achieved by adjusting the PEDIATRIC CROWN. Machining of the opposing natural tooth is not required.

Restoration of the tooth is simple and quick, resulting in a bioesthetic, functional final result that blends perfectly with the natural dentition. The required preparation is minimal and limited to the extent of caries. Therefore, there is no risk of iatrogenic exposure of the pulp of the deciduous tooth.

The PEDIATRIC CROWNs are cemented in place with the same material they are made of, resulting in a stable bond of the entire restoration (between dentin/enamel + composite + PEDIATRIC CROWN). edelweiss PEDIATRIC CROWNs can also be cemented in place with conventional glass ionomer cement or resin-modified glass ionomer cement (KGIZ).

edelweiss PEDIATRIC CROWNs

are made of a laser sintered barium glass, which makes them both highly antibacterial and plaque resistant. These crowns are biocompatible; they have the same abrasion as natural teeth, hence the edelweiss PEDIATRIC CROWN does not damage the antagonist tooth. The mesial and distal margins of the edelweiss PEDIATRIC CROWN follow the natural gingival line of the milk teeth. 

The edelweiss PEDIATRIC CROWN perfectly imitates the natural milk tooth in both form and function. The pre-fabricated, bio esthetical morphology allows for a quick and safe treatment. You can achieve maximum esthetical results, which are minimally invasive, in one appointment. No matter what the dental situation, edelweiss has the right crown for it.

Sizes

One size for all

Based on a study of all shapes and size variations of natural tooth anatomy, prefabricated and contourable universal PEDIATRIC CROWN shapes for the upper and lower arch were developed in the following range of sizes (Small, Medium, Large).

The choice

The choice of the tooth shape is performed with the available Sizing Guide (edelweiss PEDIATRIC CROWN 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 PEDIATRIC CROWN. Adjustments can be illustrated directly on the template.

Shade Range

edelweiss Shade Guide

edelweiss PEDIATRIC CROWNs consist of the shade Enamel – Vita Enamel AO. The respective dentin and enamel shades used to cement the edelweiss PEDIATRIC CROWN will determine the final shade tone of the restoration.

Shade Selection

Placing the enamel VENEER (same shade as PEDIATRIC CROWN) 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…

5 x Dentin

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 x Enamel

Enamel shade intensifies the translucency, which increase the true opalescence for all optical variations found in natural dentition.

Basic Tint:
Enamel

3 x 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.

edelweiss Shade System

edelweiss PEDIATRIC CROWN consist of the shade Enamel – Vita Enamel AO.
The respective dentin and enamel shades used to cement the PEDIATRIC CROWN will determine the final shade tone of the restoration.

Example: edelweiss PEDIATRIC CROWN (Vita Enamel Shade AO) cemented with Dentin Shade A3 (Vita Dentin Shade A3) will result in the Vita Dentin Shade A3.
