Advantages
Glass Ceramic B40 excels in its combination of high strength and superior translucency, outperforming many conventional dental ceramics. It is easy to machine, allowing for efficient production of restorations with consistent fit and finish. The natural color reduces the need for extensive post-processing, saving time for dental laboratories. It exhibits excellent wear resistance, maintaining its integrity even with frequent chewing. Additionally, its biocompatibility ensures no irritation to gums or oral mucosa, providing patients with a comfortable and safe restoration experience.
Application Field
Glass Ceramic B40 is primarily used for fabricating veneers, inlays, onlays, jaw veneers, anterior single crowns, and posterior single crowns. It is perfect for patients who desire both aesthetic appeal and functional reliability in their dental restorations. Whether restoring damaged, decayed, or discolored teeth, it can effectively restore tooth structure and appearance. Suitable for anterior teeth cosmetic restoration and posterior teeth functional repair, it meets the diverse needs of dental clinics and patients, ensuring long-lasting and natural-looking results.
