YUCERA ultra translucent zirconia UT multilayer dental zirconia
disc for porcelain teeth
Sintering
Every batch of zirconia block has gone though a completely
sintering test. The sintering methods have a great impact on
blocks’ properties, such as translucency, dyeing results, strength,
hardness and ageing resistance, which will affect the blocks’ final
stability. Therefore, please follow the sintering curve of it.
The translucency of restorations is closely related to sintering
temperature and regular maintenance of sintering furnace. Please
follow the below temperature chart.
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.
