Product Description
Dental Zirconia block is a high-tech biomaterial that is widely used in dental restorations due to its excellent biocompatibility. It is highly regarded for its non-reactive nature, which means that it is less likely to cause irritation or allergic reactions in the gums compared to various metal alloys, including gold.
Zirconium's non-reactive properties make it suitable for use in the oral cavity as it reduces the potential for allergic reactions, irritation, and corrosion that can be caused by metals. This is especially important when it comes to dental restorations, as these materials come into direct contact with the oral tissues for extended periods.
Using zirconia in dental restorations can help ensure patient comfort and minimize the risk of adverse reactions. Additionally, dental zirconia block offers several other advantages, including high strength, durability, and excellent aesthetics. It can be milled and shaped into precise dental prosthetics, allowing for accurate and natural-looking tooth restorations.
