Introduction
EN
Thank you for choosing Celtra Ceram veneering porcelain. For more than
®
100 years, Dentsply Sirona has been shaping the dental industry with innovative
products designed to establish a new standard in esthetics and quality in
fabricating all-ceramic dental prostheses. We are pleased to introduce this new
product system with the highest level of performance our customers demand.
Indications
Celtra Ceram is suitable for veneering all-ceramic frameworks.
Compatibility
Celtra Ceram is designed exclusively for dental use only by trained
professionals. Specifically, it is a low-fusing, leucite-reinforced feldspathic
ceramic optimized for veneering and characterizing all ceramic frameworks
(see below) in a dental laboratory.
With a coefficient of thermal expansion (CTE) of 9.0 x 10 K (25-500 °C)
-6 -1
and a firing temperature of 770 °C (1st dentin), Celtra Ceram is suitable for
lithium disilicate frameworks. A firing temperature of 780 °C (1st dentin) is
recommended for zirconia substrates.
