Competitive Advantages
1. Adopts 4D multi-layer gradient technology design, enabling a more precise simulation of the natural optical properties and color
gradients of teeth. It delivers direct color manifestation after sintering without the need for internal staining, significantly improving
processing efficiency.
2. With a flexural strength of 800-1300MPa and a high translucency of 46%-53%, it outperforms competing products in terms of
performance. It perfectly balances the durability of restorations with superior aesthetic results.
3. It offers a wide range of color options with stable color rendering and natural transition effects on the incisal edge. Suitable for
single crowns, multi-unit bridges, and implant-supported restorations, it meets the full-scene repair needs for high-end and
mid-to-high-end clinical applications.
