SUOYI Colored Dental Yttrium Stabilized Zirconia Powder (Pink, Yellow, Gray)
1. Aesthetic Fit: Precisely Replicating Natural Tooth Color Layers
1) Full-Range Natural Staining: Based on a high-purity yttrium-stabilized zirconia base (whiteness L>95), combined with a professional staining system, it can achieve full-range color coverage from cool-toned ivory white to warm-toned amber yellow, precisely matching the natural tooth color of patients of different skin tones and ages, solving the pain points of traditional materials' single staining and obvious color difference from natural teeth.
2) Long-Lasting and Stable Color: Using nano-level pigment penetration technology, pigment particles are uniformly embedded in the zirconia crystal phase structure. After high-temperature sintering at 1350℃, the color does not fade or yellow, maintaining the same vibrant texture as natural teeth even after long-term use, avoiding the embarrassment of discoloration of the restoration later.
3) Gradient Translucency Effect: By adjusting the yttrium oxide doping ratio (3Y-5Y gradient adjustable), a natural and translucent gradient from enamel to dentin is achieved in the restoration. Anterior tooth restorations utilize the 5Y ultra-transparent type, with a light transmittance approaching that of natural teeth's lithium disilicate glass-ceramic. Posterior tooth restorations employ the 3Y high-strength type, balancing strength and natural semi-transparency to meet the aesthetic and personalized needs of the entire dentition.
2. Mechanical Properties: "Ceramic Steel" Balancing Toughness and Durability
1) Stress-Induced Toughening Mechanism: The 3Y-TZP base material possesses unique stress-induced phase transformation toughening properties. When the restoration is subjected to chewing pressure, the tetragonal zirconia transforms into the monoclinic phase, absorbing crack propagation energy. Bending strength reaches over 1000 MPa, and fracture toughness reaches 7 MPa·m¹/², twice the fracture resistance of alumina abutments, capable of withstanding repeated impacts from long-term chewing.
2) Dense Sintering Guarantee: The powder, prepared using spray granulation technology, achieves a particle size distribution concentration of over 95%, uniform molding density, and after isostatic pressing and high-temperature sintering, a density exceeding 98% of the theoretical density is achieved. Surface smoothness Ra < 0.1μm effectively reduces food residue and bacterial adhesion, extending the lifespan of the restoration.
3) Precise Shrinkage Control: The powder shrinkage rate is stably controlled at 22±2%, resulting in a pre-sintered green body with moderate strength (50-100MPa), suitable for CAD/CAM digital machining. It is less prone to chipping and deformation during milling, and the marginal fit of the restoration can reach the micron level, reducing the risk of secondary caries.
3. Biosafety: Oral-Friendly Inert Bioceramics
1) Excellent Biocompatibility: Passes all ISO 10993 biocompatibility tests, contains no sensitizing metal elements such as nickel and beryllium, and is non-irritating and non-sensitizing to the oral mucosa, avoiding problems such as black gum lines and metal allergies caused by traditional metal-ceramic crowns.
2) Low bacterial colonization: The smooth and bio-inert surface of the zirconia abutment results in 30% lower bacterial colonization compared to titanium abutments, effectively reducing periodontal inflammation and providing a healthier oral microenvironment for implant restoration.
3) Imaging compatibility: Free from metal artifacts, it does not interfere with CT or MRI scans, facilitating follow-up monitoring of oral tissue health and ensuring early detection and treatment of oral diseases.
4) Convenient processing: Adaptable to the entire digital treatment process.
1) Highly adaptable powder properties: The equiaxed grain structure leads to isotropic shrinkage, making it compatible with mainstream CAD/CAM equipment. Uniform cutting resistance during milling ensures high precision and significantly reduces clinical processing errors.
2) Easy handling of pre-sintered blanks: The moderate strength of the pre-sintered blanks facilitates rapid milling and minimizes breakage during handling and processing, reducing material waste and rework costs and improving clinical treatment efficiency. 3) Personalized Customization Support: Supports digital scanning design and 3D printing, allowing for precise customization of restorations based on patient oral scan data. This upgrades from "standardized restoration" to "personalized restoration," meeting the needs of complex tooth loss restorations.
5. Cost Advantage: High Cost-Effectiveness
1) Controllable Raw Material Costs: Leveraging the advantages of the domestic rare earth industry chain, yttrium oxide accounts for less than 7% of costs, compared to 64% for overseas manufacturers, providing a significant cost advantage. Even with a sharp rise in overseas yttrium oxide prices, product prices remain stable.
2) Low Life-Cycle Costs: Restorations have a lifespan exceeding 15 years, far longer than traditional materials such as resin and metal-ceramic, reducing the frequency and cost of subsequent restorations and offering outstanding long-term cost-effectiveness.
3) Stable and Reliable Supply Chain: SUOYI has achieved independent control and large-scale production of raw materials, ensuring a stable supply of different types of colored dental zirconia powder, guaranteeing continuity of clinical treatment.
