Zirconia is widely selected for its high flexural strength, fracture resistance, and biocompatibility. Full-contour zirconia performs well in posterior zones, while layered zirconia offers enhanced esthetics for visible regions.
Our workflow supports stain-and-glaze characterization, occlusal adjustment control, and margin precision for predictable fit and function. Advanced multi-layer zirconia blocks deliver natural gradient translucency without the need for porcelain layering.
| Property | Zirconia (monolithic) | PFM | Emax (Lithium Disilicate) |
|---|---|---|---|
| Flexural strength | 1,200 MPa | ~800–1000 MPa (metal) | 360–460 MPa |
| Esthetics | Good–excellent (multilayer) | Moderate (opaque core) | Excellent (translucent) |
| Tooth reduction | 1.0–1.5 mm | 1.5–2.0 mm | 1.2–1.8 mm |
| Chipping risk | Very low (monolithic) | Moderate (porcelain layer) | Low (monolithic option) |
| Cost efficiency | Mid–high range | Most economical | Premium |
Intraoral scan or high-res model scan
Virtual wax-up, connector optimization
High-speed milling, 1500°C sintering
Individual staining, glaze, final polish
High-strength, metal-free solutions for demanding cases
Case #Z324: Severe occlusal wear, existing amalgam restorations
Pre-operative condition with loss of vertical dimension
Monolithic zirconia crowns #19–21, #30–31 — optimal function
18‑month recall: no wear on opposing, excellent soft tissue health
Gradual transition from high-strength core to incisal translucency. Ideal for anterior to premolar regions without external staining.
Self-adhesive resin cement for conventional retention; adhesive bonding after airborne-particle abrasion for resin-bonded retention.
High-gloss polishing kit reduces antagonist wear and enhances surface smoothness, eliminating the need for glazing in many cases.
Expert answers on strength, esthetics, and clinical handling
Yes, with high-translucency multilayered zirconia (e.g., 5Y-TZP), it provides excellent esthetics comparable to lithium disilicate while maintaining superior strength. We recommend monolithic layered zirconia for single anterior units.
Zirconia crowns have a reported 10‑year survival rate above 94% for posterior teeth, similar or better than PFM, with lower risk of porcelain chipping. Metal-free nature also eliminates allergic concerns.
Absolutely. We support full-arch implant-supported frameworks and long-span (up to 8-unit) conventional bridges using high-strength 3Y-TZP. Proper connector design and framework thickness are critical.
When highly polished, monolithic zirconia is gentle on opposing enamel. Our finishing protocol includes dedicated polishers to achieve a smooth surface, minimizing antagonist wear.
Deyu Dental Lab provides a 5‑year limited warranty against framework fracture and material defects. Any fit or esthetic issues are addressed with remake or adjustment promptly.
Standard chamfer or rounded shoulder finish line (minimum 0.5 mm axial reduction, 1.0 mm occlusal). For high-translucency zirconia, we recommend using a diamond bur with water spray to avoid microcracks.
