Crowax Modeling Wax – Renfert
Brand: Renfert • SKU: H01010 • Price: €18.95 incl. VAT
Crowax is a dental carving wax supplied in a box as a universal medium-hard wax, designed for wax-ups, occlusal anatomy and crown & bridge workflows. It can be worked with a flame or with a heated wax instrument while maintaining excellent dimensional stability.
- Low thermal shrinkage
- Easy modeling & scraping
- Transparent version: burns residue-free
- Flame or electric wax tool
Crowax dental carving wax – precision and control in the lab
- Low shrinkage: better fit accuracy and more reliable contacts after casting/pressing.
- Clean carving: the wax is easy to scrape and refine (ridges, grooves, contact points).
- Transparent version: residue-free burnout, ideal for pressed ceramics and all-ceramic workflows.
- Inorganic pigments: comfortable visual readability for morphological wax-ups and occlusal anatomy.
- Fast handling with a Bunsen flame or electric tool: controlled application and homogeneous surface.
Lab tip (stable wax-up)
- Add thin layers
- Avoid overheating
- Smooth with gentle heat
- Isolate the stone first
Dental applications
- Wax-up (anatomy, volume control, occlusal verification).
- Modeling for crowns, inlays/onlays, bridges.
- Indications for all-ceramic and pressed ceramic (transparent version).
- Pattern work / frameworks depending on the lab protocol.
Color choice is mainly about contrast and shape readability: beige for wax-ups, green/blue for strong relief contrast, gray for neutrality, red for cervical areas/marking.
How to use (simple protocol)
- Isolate the model (dry stone) with a suitable separator, then let it dry.
- Soften Crowax with a flame or a heated wax instrument: steady heat, no overheating.
- Apply in small additions, condense gently without stretching, then sculpt.
- Trim/scrape precisely: grooves, marginal ridges, embrasures.
- Before investing: check thicknesses, contacts and high spots.
Tip: an overly hot tip creates bubbles and internal stresses. Moderate, consistent heat works best.

FAQ
How do I achieve a clean wax-up with Crowax?
Work on a properly isolated and fully dry model to reduce sticking and prevent tearing during scraping. Melt Crowax using consistent heat (soft flame or electric wax tool) and add wax in small increments. Shape the main volumes first (cusps, marginal ridges), then refine grooves and embrasures. Finish with light scraping: Crowax is designed to be reworked cleanly, helping you obtain precise contours without smearing.
Which Crowax color should I choose for occlusal modeling and wax-ups?
The choice mainly depends on contrast and your lab routine. Beige supports morphological reading (ideal for wax-ups). Green/blue offer strong contrast on stone to spot relief and contact points. Gray is neutral and convenient for photo checks, while red can help with cervical areas/marking. For pressed ceramics, choose the transparent version for clean burnout.
How can I prevent bubbles and distortion during waxing?
Bubbles often appear when the tool is too hot: the wax overheats, traps air and creates internal stresses. Use moderate heat, apply wax in thin additions and condense without stretching. Avoid thermal shocks as well: let the pattern return to room temperature before major rework. For smoothing, prefer gentle, brief heat rather than adding lots of wax. These habits improve dimensional stability and reduce distortion in subsequent steps.
Can Crowax be used with both a flame and an electric wax tool?
Yes. Crowax is designed for both Bunsen flame work and electric heated wax instruments. With an electric tool, you get better heat control and precision for fine areas (grooves, embrasures, margins), with less risk of overheating when temperature is properly set. With a flame, keep a steady distance and short heating cycles, especially on thin sections. In both cases, consistent heat is the key to stable, easy-to-scrape wax.
