High Strength Dental Ceramics

Dental porcelain has very stable chemical properties and outstanding esthetics which are unlikely to be influenced by time.

High strength dental ceramics.

Durox alumina ceramics offer high thermal stability. Celtra is the new generation of high strength glass ceramics zirconia reinforced lithium silicate zls. It has similar thermal conductivity and coefficient of thermal expansion to enamel and dentine and exhibits high compressive strength. Developments over the last 10 years in ceramic materials science for dental applications have led to a class of high strength materials e g alumina and zirconia based ceramics that potentially provide better fracture resistance and long term durability than traditional porcelain and other ceramic alternatives.

However the tensile strength of dental porcelain is very low 20 60 mpa. N fusing temperature 200 250 c lower than metal framework low fusing ceramics synthetic ceramics metal ceramics no natural raw materials made of high purity chemicals. It has similar thermal conductivity and coefficient of thermal expansion to enamel and dentine and exhibits high compressive strength. Our durox aluminum oxide is a cost effective industrial ceramic material used to make components with high tensile and high dielectric strength.

The unique microstructure of zls allows outstanding physical properties exquisite beauty strength and speed.

Celtra delivers an optimized balance of translucency and natural opalescence resulting in a game changing chameleon effect.
