High-Quality Wax Discs for Dental Laboratories | OnePro Dental

Milling & Casting Workflow:

Step 1: CAD Design & Milling (20-40 minutes)

• Design restoration framework in CAD software (3Shape, Exocad, DWOS)
• Add appropriate wax compensation (typically 1-2% for metal shrinkage)
• Recommended bur: 1.0-3.0mm diameter carbide burs
• Milling speed: 20,000-40,000 RPM (lower than PMMA)
• Feed rate: Moderate (wax is soft but can melt with excessive heat)
• Use dry milling or minimal coolant (wax is sensitive to water)
• Keep wax cool during milling to prevent deformation

Step 2: Carving & Refinement (10-20 minutes)

• Remove milling tabs carefully with sharp instruments
• Refine details with wax carving tools if needed
• Smooth surfaces with a soft cloth or fine sandpaper
• Check fit on die or model
• Add sprues (wax rods) for metal flow during casting
• Ensure proper sprue placement for optimal metal flow

Step 3: Investment & Burnout (4-6 hours)

• Attach wax pattern to sprue base
• Mix and pour investment material around wax pattern
• Allow investment to set (30-60 minutes)
• Burnout cycle:
• • Room temperature → 300°C: Slow heating (2-3 hours) to melt wax
• • 300°C → 700°C: Continue heating to burn out wax completely
• • Hold at 700°C for 30-60 minutes for complete burnout
• • Cool to casting temperature (varies by metal alloy)

Step 4: Metal Casting & Finishing

• Cast molten metal into hot investment mold
• Allow to cool and solidify
• Divest (remove investment material)
• Cut off sprues and clean casting
• Finish and polish metal restoration
• Verify fit and make final adjustments

🔥 Burnout is Critical: Proper burnout ensures complete wax removal with zero residue. Our wax discs burn out cleanly at 500-700°C, leaving no ash that could compromise casting quality. Incomplete burnout can cause porosity and defects in metal restorations.

Why Choose Wax Discs for Casting?

The Dental Wax Discs are specifically designed for lost-wax casting with superior performance:

• Complete Burnout: 0% ash residue ensures flawless metal castings without porosity or defects
• Minimal Thermal Expansion: <0.3% expansion maintains dimensional accuracy throughout casting
• Excellent Machinability: Easy to mill with CAD/CAM systems for precise, repeatable results
• Superior Detail Reproduction: Captures fine details that transfer directly to metal casting
• Versatile Applications: Suitable for crowns, bridges, partial dentures, and implant components
• Cost-Effective: Affordable solution at $5.90-$6.90 per disc
• 4 Color Options: Easy workflow organization and differentiation

Wax vs Other Dental Materials

Recommendation: Choose Wax Discs for metal casting (crowns, bridges, partial dentures, implant components). Choose PMMA for temporary restorations. Choose Zirconia for permanent all-ceramic restorations.

The Dental Wax Discs are an excellent choice for labs seeking high-quality casting wax for metal restorations.

Frequently Asked Questions (FAQ)

💎 Product Features & Lost-Wax Casting

Q: What is lost-wax casting, and why use wax discs?
A: Lost-wax casting is a precision technique for creating metal dental restorations. You mill or carve the restoration in wax, embed it in investment material, burn out the wax (leaving a cavity), then pour molten metal into the cavity. Wax is ideal because it's easy to work with, captures fine details, and burns out completely without residue.

Q: What makes OnePro Wax Discs different from traditional carving wax?
A: Our wax discs are specifically formulated for CAD/CAM milling, providing consistent quality and precision that's difficult to achieve with manual carving. They offer excellent machinability, minimal thermal expansion (<0.3%), and complete burnout (0% ash residue) - superior to many traditional waxes.

Q: Do the wax discs burn out completely?
A: Yes! Our wax discs achieve 100% complete burnout at 500-700°C with 0% ash residue. This ensures flawless metal castings without porosity, defects, or contamination. Incomplete burnout can compromise casting quality.

Q: What is thermal expansion, and why does it matter?
A: Thermal expansion is how much the wax expands when heated. Our wax has minimal thermal expansion (<0.3%), which maintains dimensional accuracy throughout the casting process. High thermal expansion can cause distortion and a poor fit.

🔧 Milling & Processing

Q: Which CAD/CAM systems are compatible with wax discs?
A: Wax Discs are compatible with all major CAD/CAM milling systems including Roland, VHF, Amann Girrbach, Sirona, and more. Available in 98mm Open System and 95mm Zirkonzahn formats.

Q: What milling parameters should I use for wax?
A: Recommended parameters:
• Bur size: 1.0-3.0mm diameter carbide burs
• Milling speed: 20,000-40,000 RPM (lower than PMMA)
• Feed rate: Moderate
• Milling type: Dry or minimal coolant
• Important: Keep wax cool during milling to prevent melting/deformation
• Add 1-2% compensation for metal shrinkage during casting

Q: Can I carve wax discs by hand after milling?
A: Yes! After CAD/CAM milling, you can refine details with traditional wax carving tools. The wax is soft enough for hand carving but firm enough to hold milled details.

Q: What is the burnout temperature and cycle?
A: Recommended burnout cycle:
• Room temp → 300°C: Slow heating (2-3 hours) to melt wax
• 300°C → 700°C: Continue heating to burn out wax completely
• Hold at 700°C for 30-60 minutes for complete burnout
• Cool to casting temperature (varies by metal alloy)
Total cycle: 4-6 hours including cooling

🎨 Color Selection

Q: What's the difference between the 4 colors?
A: All colors have identical physical properties (melting point, burnout, thermal expansion). Choose based on workflow preference:
• Blue: High contrast for crown/bridge frameworks
• White: Natural appearance for diagnostic wax-ups
• Brown: Traditional color for partial denture frameworks
• Grey: Neutral color for implant components

Q: Can I mix different colors in one case?
A: Yes! You can use different colors for different components to organize your workflow. For example, use Blue for crowns and Brown for partial denture frameworks in the same case.

🏥 Clinical Applications

Q: What types of restorations can I make with wax discs?
A: Wax discs are ideal for:
• Crown and bridge frameworks (metal and PFM)
• Partial denture frameworks (cast metal)
• Implant abutments and bars
• Orthodontic appliances (cast metal)
• Inlays and onlays
• Diagnostic wax-ups and prototypes

Q: Can wax discs be used for PFM (porcelain-fused-to-metal) restorations?
A: Yes! Wax discs are excellent for creating metal frameworks for PFM restorations. Mill the framework in wax, cast in metal, then apply porcelain to the metal substructure.

Q: Are wax discs suitable for partial denture frameworks?
A: Yes! Wax discs are ideal for cast metal partial denture frameworks. The complete burnout ensures high-quality castings with excellent fit and strength.

Q: Can I use wax discs for implant components?
A: Yes! Wax discs work well for custom implant abutments, bars, and other implant components. The precision and clean burnout ensure an accurate fit.
