HT means high translucency,LT means low translucency. Amber ceramics areall in whitening HT-0M1, mainly used for veneer restoration.

Products advantages

Advantages
1.High strength: It has extremely high bending strength, which enables it to withstand large bite forces in the mouth and is suitable for restorations in high-stress areas such as posterior teeth.
2.Excellent aesthetic effect: It has optical properties similar to natural teeth, including light transmittance and fluorescence,and can blend well with the surrounding natural teeth to provide natural and beautiful restorations.
3. Excellent processability: It has good processability and can be accurately cut and carved through CAD/CAM technology to meet personalized restoration needs and reduce manual operation errors.
4. Biocompatibility: It has excellent biocompatibility, will not cause adverse reactions in oral tissues, and is safe and reliable for long-term use.
5. Durability: It has excellent corrosion resistance and anti-aging properties, and can maintain the functionality and aesthetics of the restoration for a long time.
6. Versatility: Due to its high strength and excellent aesthetic effect, this material can be used in a variety of restoration applications, such as full crowns, inlays, veneers, and bridge restorations of single or multiple teeth, with a wide range of indications.
