Zirconia (ZrO2) 3D Printing: Precision 3D Printed Dental Tooth Implants
Introduction
Zirconia (ZrO₂) 3D printing has become a breakthrough technology in the dental field, producing high-precision, durable, and biocompatible dental tooth implants. Utilizing ceramic 3D printing technologies such as Vat Photopolymerization and Material Extrusion, Zirconia (ZrO₂) dental components achieve excellent mechanical strength, aesthetics, and long-term stability.
Compared to conventional milling methods, Zirconia 3D printing shortens lead times, reduces material waste, and enables patient-specific, highly complex implant designs with minimal post-processing.
Applicable Material Matrix
Material | Purity (%) | Flexural Strength (MPa) | Hardness (HV10) | Fracture Toughness (MPa·m¹/²) | Translucency (%) |
|---|---|---|---|---|---|
>99% | 900–1200 | 1200–1400 | 6–10 | Medium | |
>99% | 700–900 | 1000–1200 | 3–6 | High | |

Material Selection Guide
3Y-TZP Zirconia (3 mol% Yttria-Stabilized): Excellent for root-form dental implants due to its superior strength, fracture toughness, and aging resistance.
5Y-PSZ Zirconia (5 mol% Yttria-Stabilized Partially Stabilized): Ideal for anterior restorations requiring high translucency and aesthetic appearance.
4Y-PSZ Zirconia: Suitable for bridge frameworks and posterior implants, balancing strength and translucency.

Process Selection Guide
Superior Strength and Durability: Zirconia implants deliver flexural strengths up to 1200 MPa, outperforming traditional dental ceramics in mechanical performance.
Biocompatibility: In the human body, zirconia exhibits excellent tissue integration, low bacterial adhesion, and minimal allergic reactions.
High Aesthetic Quality: The natural white color and optional translucency of zirconia provide outstanding visual outcomes for visible dental restorations.
Precision Fit: 3D printing enables highly accurate, patient-specific geometries directly from intraoral scans, reducing clinical adjustment time.
Case In-Depth Analysis: Customized 3Y-TZP Zirconia Dental Implants
