HUGE Duraplex Multilayer PMMA Disc — 98.5 × 20 mm, Shade A3
SKU 489382 · HUGE DENTAL · Duraplex · Shade A3
Duraplex is not ordinary PMMA. HUGE positions it as a nano-reinforced evolution of conventional acrylic, built for restorations that have to survive in the mouth for a long time rather than a fortnight — long-term provisionals, All-on-X conversion prostheses, and permanent structures for removable dentures. The most-prescribed shade in dentistry. If you stock one disc, most labs stock this one.
The Five Questions Labs Actually Ask
1. Hardness? 26 HV0.2 — against 15 for regular PMMA on HUGE’s own comparison. That is the number behind the wear resistance.
2. Flexural strength? 140 MPa, with a modulus of elasticity of 2,400 MPa. Both figures are from HUGE’s published parameter table.
3. How many layers? It is a multilayer disc, shade-graded from cervical to incisal so the transition reads like a natural tooth rather than a printed band. HUGE does not publish a layer count, and we are not going to invent one — if the exact count matters to your case, call us on 954-874-6325 and we will get it from the manufacturer in writing.
4. Which colours? BL1, B1, A1, A2 and A3, all at 98.5 × 20 mm, all stocked here. This disc is shade A3.
5. Wet or dry milling? HUGE publishes no wet-or-dry restriction on Duraplex. As a material class, Cad/Cam PMMA mills both ways — dry is what most lab units run and is the usual default; wet gives a finer surface and controls dust, at the cost of drying and chamber cleaning. On dry, run a slower RPM protocol. Treat that as general PMMA practice, not a HUGE instruction — follow your milling unit’s PMMA profile, and call us if you want us to confirm parameters with HUGE for your specific machine.

Parameters as published by HUGE DENTAL. HUGE notes all technical parameters originate from its own laboratory.
Against Regular PMMA
| Measure | HUGE Duraplex | Regular PMMA |
|---|---|---|
| Hardness (HV0.2) | 26 | 15 |
| Wear loss, 84 h at 30 rpm | 0.24% | 0.43% |
| Translucency | 67% | 59% |
Lower wear loss and higher hardness are the same story told twice: the restoration keeps its occlusal anatomy and its polish for longer. On a conversion prosthesis a patient may wear for twelve months or more, that is the difference between a case you review and a case you remake.
Why This Matters For All-on-X
This is the part most PMMA specs do not tell you. Duraplex is built to the True Color System, which means it shade-matches HUGE’s MM4D zirconia. Measured as colour difference (ΔE) against that zirconia:
| Zone | Duraplex ΔE | Regular PMMA ΔE |
|---|---|---|
| Incisal | 1.89 | 5.29 |
| Middle | 1.76 | 6.01 |
| Cervical | 1.62 | 7.46 |
What that buys you: the provisional the patient approves and the final zirconia they receive are the same colour. Regular PMMA sits at ΔE 5.3 to 7.5 against the zirconia — a shift the patient sees and asks about at delivery. Duraplex sits at 1.6 to 1.9. You stop having the conversation that starts with “the temporary looked different.”
Indications

How It Compares
| Disc | Material | Flexural | Price | Built for |
|---|---|---|---|---|
| HUGE Duraplex ML 98.5 × 20 mm · this disc | Nano-reinforced PMMA | 140 MPa | $66.00 | Long-term provisionals, All-on-X conversion, permanent denture structures |
| DIGILUX SUPER CRYSTAL Hybrid 98.5 × 16 mm · SKU 416903 | Resin-matrix Hybrid CERAMIC, ~30% inorganic load | 165 MPa | $165.36 | Definitive single-unit restorations |
| VITROLUX ML PMMA 98.5 × 20 mm · SKU 477164 | Standard PMMA | Standard | $39.60 | Everyday short-term provisionals |
Read that table honestly: the Hybrid CERAMIC is the stronger material. DIGILUX SUPER CRYSTAL carries a CERAMIC network inside its polymer matrix — around 30% inorganic load — and reaches 165 MPa against Duraplex’s 140. If flexural strength alone decided the case, it would win.
It does not decide the case, because these two are not competing for the same job. Hybrid CERAMIC is a definitive material for single units, at two and a half times the price and in a thinner 16 mm blank. Duraplex is built for the work that has to be large, long-lived and affordable per arch — conversion prostheses, long-term provisionals and permanent denture structures, in a 20 mm blank with the height for a full arch.
Choose on the case, not the megapascals:
• Single definitive crown or inlay, aesthetics critical → DIGILUX SUPER CRYSTAL Hybrid
• Full-arch conversion, long-term provisional, denture structure → Duraplex
• Two-week temporary → VITROLUX at $39.60, and do not overpay for either of the others
We stock all three. Call 954-874-6325 and we will tell you which your case needs.
