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.
