Glass - An important part of high quality dental fillings

Specialty glass powder as a dental filler material
Perfect aesthetic properties
Patients’ requirements regarding aesthetics of dental restorations are rising continuously. Due to the excellent transparency of glass, the composite filling can be adapted perfectly to the natural color of the tooth by adding special pigments. Furthermore, dental fillings that contain very fine glass powder particles can be polished more easily - for a smooth and shiny smile.
High durability
As a substitute for tooth enamel – which in fact is the hardest substance in the human body – dental fillings are exposed to immense stress. The chewing muscle is the strongest human muscle and puts an enormous amount of pressure on our teeth. An optimal mixture of larger and ultra fine glass particles enables a tighter filler loading of the specialty glass powder as part of the dental composite. This leads to exceptional pressure resistance and the necessary robustness.

So called “ribbons”, which consist of casted and quenched specialty
glass, are ground in a multilevel process. -
By grinding the glass to SCHOTT NanoFine® level, a particle size of
only 180 nanometers in diameter can be produced. -
Dental composites consist of up to 80% glass powders and a liquid
resin mixture. By using very fine pigment shades, the filling can be
individually adapted to the natural dental material. -
The liquid composite can be applied layer by layer to the cavity by
using a dental syringe. -
In most cases, dental curing is usually done by light. The glass
powder offers optimal mechanical and optical properties.
For more than 40 years, SCHOTT has been developing highly pure glass powders for the dental industry. To achieve very small grain sizes with the demanded excellent transparency , the production of the glasses has to comply with high purity requirements. For this reasons, the dental glasses are melted within a special unit, which is normally used for glasses with optical quality.
