Cerec Zirconia Blocks Features
Zirconium dioxide all-ceramic tooth is a high-tech cosmetic
restoration method developed in recent years. It is made through
computer-aided design, laser scanning, and grinding by computer
programs.
It has a good translucent appearance, high density and strength,
which can solve the problem that the all-ceramic system cannot be
used as a long bridge. All-ceramic teeth have the characteristics
of perfect tight edges, no gingival inflammation, no blocking of
X-rays, etc., and their biocompatibility is better than that of
various metal crowns, and they can get a long-lasting clinical
restoration effect.
Cerec Zirconia Blocks
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.
