Inert dental glasses are a major component of composite fillings in modern dentistry. Their utilization in tooth restoration provides strength and durability, combined with an excellent aesthetic appearance. Due to their composition, the chemical reactivity of these materials is low (“inert”).
Customers can choose from several hundred product combinations, which are generated from more than ten different material compositions (glass types) with over a dozen different grain sizes.
As an additional service we can supply our inert dental glasses silanated. A silane layer increases the wettability of the glass by the resin and allows the bonding of the non-reactive dental glass to the resin components of your material.
This broad range of options enables dental composite manufacturers to choose a tailor made solution for any dental composite.
Excellent aesthetic appearance combined with strength, durability and ease of use are the main standards for highest quality composite filling materials.
SCHOTT‘s inert dental glasses enable dental composite manufacturers to choose tailor made solutions:
Consistent physical and chemical properties:
Broad range of grain sizes available:
from coarse K-grinds down to submicron SCHOTT NanoFine®
SCHOTT‘s inert dental glasses are used as an inorganic filler for dental composites and make up for 70-80% in weight, thus being the key ingredient.
Glass particles can be coated with a silane layer to allow bonding and mixing with an organic resin as well as additional ingredients, e.g. color pigments. Therefore, composite material is formed as a viscous paste, which is applied by the dentist into the cavity layer by layer, cured with a special UV-light and polished to ensure a smooth and appealing surface.
With more than 130 years of experience, SCHOTT melts all dental glasses in specially designed aggregates to produce glass of optical quality. The choice of melting technology depends on the composition and quality requirements of the individual glass type.
Depending on the desired grain size and distribution, different dry and wet grinding technologies are used to grind the raw glass into fine powder.
