«The composition of the edelweiss POST & CORE is barium glass, strontium and zinc oxide (antibacterial) embedded in resin. The crystals are sintered to a monobloc which leads to perfect mechanics within the material. The flexural strength is similar to that of natural tooth. Congruent precision laser cut dental drills creates a perfectly prepared post space to suit the anatomical variations within the root canal space. edelweiss POST & CORE system is available in 3 different sizes based on the tooth position corresponding to anterior, premolar and molar regions.»

The edelweiss POST & CORE system consists of a post-and-core monoblock (post and abutment) made of laser-tempered and pre-polymerized highly filled nanohybrid composite and is used for the restoration of endodontically treated teeth. The conical post has a smooth surface and fits into post beds with a diameter of 1.4 mm and 1 mm. This makes it ideal for use in both the anterior and posterior regions. The conical profile of the post ensures optimal adaptation to the post bed. The translucency of the post allows even light emission for complete polymerization even in the apical region. The unique laser coating process allows for improved composite technology with superior mechanical properties.
The edelweiss POST & CORE system ensures a perfect esthetic result thanks to its translucent root post and integrated opaque post build-up.
The POST & CORE system is bonded to the root dentin with the same material it is made of, so that the root, dentin/cervical enamel, composite cement and POST CORE system form a single unit. This ensures maximum retention of the post in the root canal.

Properties edelweiss POST & CORE-System
- The conical post allows deep curing due to its translucency
- The opaque post build-up ensures a maximum esthetic restoration result
- Excellent retention thanks to the monoblock effect
- Easy to use
- Can be processed like dentin; preparation can be carried out directly in the mouth
- Easy adaptability
- The modulus of elasticity corresponds to that of natural tooth and prevents a wedging effect
- Unsurpassed radiopacity (radiopaque)
- Excellent adhesion to the root canal
Properties edelweiss Flowable Nano-Hybrid Composite
(recommended for cementing the POST & CORE system and adjusting the abutment).
- Easy to use
- Excellent working properties
- Fast and easy application
- Outstanding physical properties
- Antibacterial fillers
- Biocompatible
Indications
- Restoration of endodontically treated teeth
- Remaining tooth structure no longer provides sufficient retention
- For support during tooth reconstruction
- To stabilize the restoration against tensile, bending and shearing forces
- Severely reduced crown length, e.g. in case of attrition or abrasion
- In the case of a devitalized tooth that needs to be protected from fracture, as an abutment for a bridge
- Dentine collar (ferrule) less than 2-3 mm
- When the esthetic appearance plays an important role
edelweiss POST & CORE
«The difference lies in the force buffer of the monobloc.»
The edelweiss POST & CORE system
is a laser sintered monobloc designed to avoid the wedging effect. The posts have a conical shape for perfect post space adaptation. The translucency of the post allows uninterrupted light transmission for complete polymerization even at the most apical portion of the post.
The edelweiss POST is further enhanced by a core buildup into a single monobloc which is specifically designed to mimic the natural tooth form. The opaque core buildup in Vita Shade A1 is supplied in various anatomical forms based on the natural tooth form thus simplifying the preparation procedure. Any further preparation of this core buildup will then result in a core similar to that of the natural tooth structure. The edelweiss POST & CORE´s natural tooth design form enables for better retention of the final clinical crowns.
The adhesive bonding further contributes to avoiding the wedging effect by providing a single monobloc between the adhesive layer and the composite post. It is now possible to carry out the post & core placement together with the final restorative treatment in a single appointment, which is both time and cost effective for patient and dentist alike.
Simple and Quick
The edelweiss POST & CORE system is a simple and a quick solution for all your post-endodontic needs. The single-phase POST & CORE glass hybrid can be customised with a true monobloc effect depending on the needs of the tooth.
It is an ideal choice for rebuilding and strengthening broken down teeth. Cementation using edelweiss flowable composite, dual cure composite material or adhesive resin cement.
Optimised workflow reduces chairtime up to 40 percent.

Preparation and Cementation - Step by Step
Root preparation
1. Remove obturation material to desired length using edelweiss POST DRILL (1000-2000 rpm).
2. Prepare the post space to the pre-determined depth using the edelweiss POST DRILL (2000-5000 rpm) with moderate pressure using water spray.
Root preparation
Confirm post space length with a radiograph.
3. Create a Countersink hole (about 2 mm) with round/oval bur in the coronal part of the post space.
4. Using the same round/oval bur create an anti-rotation slot to allow for the core part to fit snugly into the root.
Post / ROOT PREPARATION
5. The corresponding size post is tried in the canal and should fit easily within the canal without binding. The core portion of the POST & CORE can be adjusted and customized using the diamond drill and made to fit within the core space extra-coronally.
Confirm post length with a radiograph.
6. Apply a thin layer of edelweiss VENEER Bond to the surface of the post, blow dry and light cure in all directions for 20 seconds.
Clean or disinfect the root canal with 2.5-5 % sodium hypochlorite solution (NaOCl). Rinse immediately with water and dry with paper points.
Post / ROOT PREPARATION
7. Etch the root canal walls with 35 % phosphoric acid for 15 seconds, rinse and dry.
8. Apply primer-adhesive into the root canal with a thin micro brush/applicator tip, remove excess with paper points and light cure for 20 seconds.
Post Cementation
9. Cementation using edelweiss FLOWABLE COMPOSITE, light cure for 40 seconds in all directions.

10. Core adjustment: The core can be adjusted accordingly for the final restoration.
