As a medical product with ultrafine microstructure and phase transformation toughening, the nano-aesthetic Zirconia is featured with outstanding flexural strength, consistent contractile accuracy, ideal photo-permeability, optimal intraoral ageing resistance, and excellent milling and edge stability.
Available in different sizes and colors.
Product Advantage
- Outstanding milling performance, finest edge stability
- Excellent bio-compatibility, Accurate and consistent sintering properties
- Aesthetics is made possible by the super high transparency, Durability and stability of the restorations are achieved by the high strength and homogeneous microstructures
- Optimal density, remarkable strength, fracture toughness, and processing properties, Distinguished ageing resistance that ensures the durability of restorations
Biocompatibility refers to the capability of ceramic material to betolerated in the oral
environment without causing deleterious and irritant injuries to human cells nor tissues ISO (International Organization for Standardization) andADA (American Dental Association) have released fullsets of guidelines for the standardized test of biocompatibility, follow which the product safety is ensured in our laboratory.
- Cytotoxicity test
- Oral mucosal irritation test
- Delayed hypersensitivity test
- Sub-chronic systemic toxicity test
- Genetic toxicity test
- Intradermal reaction test
- AMES test
Process Control
Each step of the process has to undergo strict quality inspection, process control and repeated verification. Quality consistency is realized by minding every detail and recording any variation of parameters.
- Biological inspection under ISO 10993/ISO 7405
- Physio-chemical,mechanical and composition inspection under ISO 13356/ISO 6872
- Surface ageing, radioactivity and light transmittance inspection according to ISO 9693/ISO 6872
- Comprehensive evaluation and inspection of milling, firing and dyeing quality for each batch
- Tests for density, hardness, colour, flexural strength, microstructure, and thermal stability
Quality System
An efficient quality assurance systemruns through the entire processfrom product
development and raw material procurement to production, testing, sales after-sale service, and technical support
- ISO 9001 Quality Management System
- ISO 13485 Medical Devices-Quality Management System
- FDA Manufacturing and Management Regulations on Medical Devices

Recommended crystallization parameters
* This chart only serves as a reference. Adjustments on the sintering process shall be made when the transparency or glossiness of the restoration fails to meet the ideal status after sintering. The key to the sintering processlies not in the temperature displayed, but the appearance and surface status of the restoration after sintering.
