Dental Laboratory YUCERA Dental Zirconia Block High Translucent
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.
