Zirconia Ceramics Used on Medical Application Case
Zirconia ceramics (ZrO₂) possess exceptional physical, chemical, and biological properties, making them an ideal material for various medical applications. The following summarizes their core properties and typical applications. 1. Excellent Biocompatibility Non-toxic and non-allergenic: Zirconia does not produce rejection reactions with human tissues and does not release harmful ions, unlike certain metal alloys such as nickel-chromium. Chemically inert and stable: It will not corrode or degrade in the physiological environment (more reliable than absorbable materials), allowing for safe long-term implantation in the human body. Application Case: The incidence of tissue inflammation around zirconia implants is 60% lower than that around titanium alloy implants in dental applications. 2. Mechanical Performance Advantages Characteristics Value Medical Significance Flexural strength 900–1200 MPa Withstand high-frequency operation of surgical instr...
