Crowax / Crowax Dur Universal wax
The properties of Crowax and Crowax Dur make these waxes suitable for a wide range of uses.
Universal waxes for
• C&B techniques
> Individual crowns
> Inlays
> Bridges
> Porcelain pressing
> Wax-ups
• Model casting techniques
Crowax
• suitable for flame technique as well as electronic waxing-up.
• available in green, blue, red, beige and grey.
• Crowax beige is also suitable for wax-ups.
Crowax Dur
• harder version with a higher melting and drip point.
• ideal for use in summer / higher temperature surroundings.
• ideally suited for modelling occlusals.
• optimum carving properties
• transparent wax for full porcelain work.
Highest precision with lowest shrinkage values!
In comparison to other waxes, the shrinkage values of Crowax and Crowax Dur are considerably lower. This makes the wax particularly suitable for precision work in partial crown, onlay and inlay techniques. Owing to its low contraction Crowax has been valued for many years for general bridge work.

GEO Classic modelling waxes
GEO Classic modelling waxes are ideally suited to additive waxing-up techniques.
Their excellence lies in the optimum properties of raw material used.
• low shrinkage due to microcrystalline structure.
• quick to apply and quick to cool with its optimum melting interval.
• high surface tension.
• excellent carving properties due to its non-elastic and hard quality.
• wide assortment of colours.
Both ranges, Classic opaque and Classic transparent were designed with specific techniques in mind.
GEO-Classic opaque
• offers sharp contour details even in a liquid state due to opacity.
• behaves in a plastic manner to accentuate the relief.
• ideal for forming occlusal surfaces.
GEO-Classic transparent Special wax for full porcelain work
• especially for pressing porcelain.
• filtered many times, contains no opaque components.
• burns without residue.
• no impurities caused by metal oxides. |

Avantgarde modelling waxes
When working with an electronic waxing-up unit special demands are made on the wax used. GEO Avantgarde modelling waxes are precisely developed for this technology, which seeks to preserve the raw materials. The ideal modelling properties are maintained thus leading to precise results.
• excellent flow properties and low contraction for modelling the exterior tooth shape (GEO-Avantgarde
universal).
• excellent rigidity and strength for forming occlusal surfaces (GEO-Avantgarde occlusal).
• owing to their different qualities, GEO-Avantgarde modelling waxes cover both sets of requirements.
GEO-Avantgarde universal
Ideally suited for quick coverage of large areas with wax. Ideal for modelling bridge elements.
• low surface tension.
• low melting point.
• small contraction on hardening.
• excellent flow properties.
GEO-Avantgarde occlusal
Fulfils all requirements for modelling occlusal surfaces.
• high strength - no abrading of contact points.
• behaves in a plastic manner to accentuate the relief.
• high rigidity.
• can be easily drawn due to its high surface tension.
• ideal for filigree occlusal modelling.
• opaque appearance for defined contours and permanent control during modelling.
cervical wax
Inert wax for forming crown edges.
• low shrinkage.
• particularly stable.
• can be adapted precisely and thinly to the preparation border.
• excellent carving properties.
undercut wax
Inert wax for small undercuts and cavity coverage before inlay modelling. Excellent for flooding when forming secondary parts made of wax.
• significantly softer than cervical wax.
• gentle elasticity.
• good adaptation and carving properties.
• very low shrinkage.
milling wax
Developed precisely to meet the mechanical working processes when using milling and carving instruments.
• small wax-shavings.

• flat, defined contour surface.
• ideally suited for occlusal surface modelling.
block-out wax
For blocking out and preparing models for duplication.
• optimum adaptation to plaster or metal.
• high opacity means it can be seen even in thin layers.
• suitable for manual and thermal blocking out.
• high melting point of 86°C (187°F) – no softening when duplicating.
• no reaction with monomers, or the usual trade silicones and plasters.
sticking wax
Special wax for fixing denture parts.
• for preparing repair or welding work.
• low shrinkage.
• high strength and brittleness – wax breaks immediately if the position of the foxed pieces is changed.
• ideal sticking properties for all dental materials. |

Dipping waxes
Special waxes for processing within an electronic wax die pot.
Precise preparation, e.g., using our hottys, maintains the excellent raw material properties of this high quality wax. The result: precise copings with extremely low shrinkage.
GEO-Dip Yellow / Orange / Green
Practical dipping wax pellets for refilling the wax die pot.
• high precision via low shrinkage.
• optimum viscosity at 89–91°C (192–196°F).
• reproducible, precise fitting copings with an even layer thickness.
• high stability and elasticity.
• contains no acrylic additives. The precise temperature setting on the wax die pot (see diagram) guarantees
an even, reproducible coping thickness.
Preparation:
• place a thin isolating layer on the die surface using Picosep .
• build-up of bubbles and streaks are thus prevented.
Dipping:
• support your hand comfortably.
• do a quick dip to just beyond the preparation border.
• slowly and evenly remove the die from the wax.
• just before the tip comes out hold it steady in the pot for a short time so that any excess wax can drip down.
• easy to cut off the preparation border.
• exact dosage via the GEODip container.
Colours to match your technique
The light colours of yellow and orange are ideally suited to controlling coping thickness. No optical influence when using modelling wax. The dark green colour allows the thickness of the model to be controlled when using light wax. |

• high processing temperature of 90–92°C (194–198°F).
• precise moulding of dies with minimal contraction.
• excellent scraping and cutting properties.
• guaranteed optimum precision fit and surface smoothness of the cast crown.
• stable and reversible moulded copings. |
