YUCERA Dental Materials ST Zirconia Blocks And Equipment Manufacturer Dental Porcelain False Teeth
Super Translucency Zirconia Perfect For Anterior Restorarion , Dental Zirconia Blank
YUCERA blanks are made from biocompatible zirconiumdioxyde. The yttrium oxide stabilizing protects the material against cracks and increases the tensile and compressive strength. The special grain size allocation inside the material and the added aluminium oxide also result in extra strength during milling and subsequently in clinical use. The outstanding mechanical characteristics, excellent chemical durability and the unbeaten biocompatibility combined with the translucent color predestine YUCERA as the ideal material provider for dental milling systems.
ST most translucency, apply to single crown, anterior teeth, inlay/onlay and also veneers.
To achieve expected quality, the sintering curves must be followed.
Note: please employ high-temperature furnace specially designed for denture manufacturing. It is good for ceramics sintering to prolong heating up time and cooling time properly.
1. Sintering preparation: Make sure there is enough sintering space to avoid deformation. After dyeing, the restoration must be dried. Do not heat up too quickly for it might result in cracks. Make sure the dust-proof cover is put on the crucible to keep impurity away from restorations
2. After sintering: Following the instruction to lower temperature and take out restorations. Do not reduce furnace temperature too quickly to avoid cracks.
3. The highest temperature: the highest temperature will affect the translucency and dyeing results. Make sure the accurate temperature of every step. Sinter and preserve heat according to the instruction.
