Clear PMMA Discs (10-30mm) for Dental Applications

Milling & Processing Workflow:

Step 1: CAD Design & Milling (15-30 minutes)

• Design appliance in CAD software (3Shape, Exocad, DWOS)
• No enlargement needed - PMMA does not shrink during processing
• Recommended bur: 1.0-2.5mm diameter carbide burs
• Milling speed: 30,000-60,000 RPM
• Feed rate: High (PMMA is soft and easy to mill)
• Use dry or wet milling (wet milling reduces dust and heat)
• Achieve <0.05mm margin accuracy with proper parameters

Step 2: Finishing & Polishing (15-20 minutes) - Critical for Transparency

• Remove milling tabs and smooth edges with finishing burs
• Polish thoroughly for maximum transparency:
• Use progressive grits: coarse → medium → fine → extra fine
• Polish all surfaces to remove any cloudiness or scratches
• Final polish with felt wheel and polishing compound for a crystal-clear finish
• Clean thoroughly with alcohol or ultrasonic cleaner
• Important: Proper polishing is essential to maintain transparency

Step 3: Quality Check & Cleaning

• Inspect for clarity - should be crystal clear with no cloudiness
• Check fit and accuracy
• Clean with alcohol or mild detergent
• Dry completely before delivery
• Store in a protective case to prevent scratches

Step 4: Delivery & Patient Care Instructions

• Provide patient with cleaning instructions
• Recommend cleaning with mild soap and water
• Advise against hot water (can cause warping)
• Store in protective case when not in use
• Regular cleaning maintains transparency

💡 Pro Tip: Proper polishing is critical for Clear PMMA. Any scratches or cloudiness will be visible. Use progressive polishing steps and finish with high-gloss compound to achieve crystal-clear transparency. Clean regularly to maintain clarity.

Why Choose Clear PMMA?

The Clear PMMA is specifically designed for applications requiring transparency and precise fit. Key advantages include:

• Exceptional Transparency: Crystal-clear clarity allows visualization of tooth contacts, fit, and occlusal relationships
• Superior Strength: ≥120 MPa flexural strength - same as colored PMMA for reliable durability
• Precise Fit Verification: Transparency enables easy verification of margins and adaptation
• Biocompatible: Low residual monomer (<1%) reduces risk of allergic reactions
• Versatile Applications: Ideal for splints, guards, surgical guides, and functional appliances
• Easy to Clean: Smooth transparent surface resists staining and is easy to maintain
• Cost-Effective: Affordable solution at $9.90-$13.90 per disc

Clear PMMA vs Colored PMMA

Recommendation: Choose Clear PMMA for splints, night guards, surgical guides, and functional appliances where transparency is beneficial. Choose Monolayer PMMA for temporary crowns and bridges where tooth color is needed.

Designed for Dental Laboratories

OnePro Dental works directly with dental laboratories worldwide, providing reliable CAD/CAM materials that combine performance, consistency, and cost efficiency.

The Clear PMMA Discs are an excellent choice for labs seeking high-transparency solutions for splints, guards, and surgical guides.

Frequently Asked Questions (FAQ)

💎 Product Features & Transparency Advantages

Q: What makes Clear PMMA different from colored PMMA?
A: Clear PMMA is crystal-clear transparent, while colored PMMA is opaque. Both have the same ≥120 MPa strength, but Clear PMMA allows you to see through the appliance - perfect for verifying fit, checking occlusal contacts, and surgical guide visibility. Choose Clear for splints/guards/guides, choose colored for temporary crowns/bridges.

Q: Why is transparency important for splints and surgical guides?
A: Transparency allows:
• Splints/Guards: Dentists can verify proper fit and occlusal contacts visually
• Surgical Guides: Surgeons can see through the guide during implant placement for precise positioning
• Functional Appliances: Clear visualization of tooth contacts and jaw relationships
• Patient Acceptance: Less visible, more esthetic appearance

Q: Is the strength the same as colored PMMA?
A: Yes! Clear PMMA has the same ≥120 MPa flexural strength as Monolayer PMMA - significantly higher than industry average (90-110 MPa). You get transparency without sacrificing strength.

Q: Is Clear PMMA biocompatible?
A: Yes! Our Clear PMMA has <1% residual monomer content (industry average is <2%), ensuring excellent biocompatibility and minimal risk of allergic reactions or tissue irritation. It's ISO-certified medical-grade PMMA.

🔧 Milling & Processing

Q: Which CAD/CAM systems are compatible with Clear PMMA?
A: Clear PMMA Discs are compatible with all major CAD/CAM systems including 3Shape, Exocad, DWOS, Roland, VHF, and more. Available in 98mm Open System and 95mm Zirkonzahn formats.

Q: What milling parameters should I use?
A: Recommended parameters:
• Bur size: 1.0-2.5mm diameter carbide burs
• Milling speed: 30,000-60,000 RPM
• Feed rate: High (PMMA is soft and easy to mill)
• Milling type: Dry or wet (wet reduces dust and heat)
• No enlargement needed - PMMA does not shrink

Q: How do I achieve crystal-clear transparency?
A: Proper polishing is critical:
1. Remove all milling marks with finishing burs
2. Polish with progressive grits (coarse → medium → fine → extra fine)
3. Polish ALL surfaces thoroughly - any scratches will be visible
4. Final polish with felt wheel and high-gloss polishing compound
5. Clean with alcohol for crystal-clear finish
Tip: Spend extra time on polishing - it's essential for transparency!

Q: What if the Clear PMMA becomes cloudy?
A: Cloudiness is usually caused by:
• Insufficient polishing - re-polish with finer grits
• Scratches - polish out scratches with progressive grits
• Contamination - clean thoroughly with alcohol
• Heat damage during milling - use wet milling or reduce speed
Proper polishing should restore crystal-clear transparency.

🏥 Clinical Applications

Q: Is Clear PMMA suitable for occlusal splints?
A: Yes! Clear PMMA is ideal for occlusal splints and bruxism guards. The ≥120 MPa strength provides excellent durability even under heavy grinding forces, and the transparency allows dentists to verify proper fit and occlusal contacts.

Q: Can Clear PMMA be used for surgical implant guides?
A: Yes! Clear PMMA is excellent for surgical implant guides. The crystal-clear transparency allows surgeons to see through the guide during implant placement, ensuring precise positioning. The dimensional stability guarantees accurate transfer from planning to surgery.

Q: Is Clear PMMA suitable for night guards?
A: Yes! Clear PMMA is perfect for night guards. The high strength ensures long-term durability, and the transparent appearance is more esthetic and less visible than colored materials.

Q: Can Clear PMMA be used for temporary crowns?
A: While possible, Clear PMMA is not ideal for temporary crowns as it's transparent rather than tooth-colored. For temporary crowns and bridges, we recommend Monolayer PMMA (17 Vita shades) or Multilayer PMMA (3-layer gradient) for better esthetics.

🧼 Cleaning & Maintenance

Q: How should patients clean Clear PMMA appliances?
A: Instruct patients to:
• Clean daily with mild soap and lukewarm water
• Use soft toothbrush - avoid abrasive cleaners
• Rinse thoroughly after cleaning
• Avoid hot water (can cause warping)
• Store in protective case when not in use
• Avoid alcohol-based mouthwashes (can cause cloudiness)

Q: How do I maintain transparency over time?
A: To maintain crystal-clear transparency:
• Clean regularly with mild soap and water
• Avoid abrasive cleaners or toothpaste
• Store in protective case to prevent scratches
• Avoid exposure to high heat
• Re-polish if minor scratches develop
With proper care, transparency is maintained indefinitely.

📦 Ordering & Packaging

Q: How many appliances can I get from one disc?
A: Typical yield from a 20mm disc:
