Dental & Medical Glasses

Cera Dynamics (CDL) has been a supplier of glasses for dental restoratives for over twenty years. Using our unique melting method we are able to produce a wide-range of glasses, particularly specialising in the well-defined chemical control and high-fluorine glasses used for dental applications.

Cera Dynamics produces custom composition glasses for more than 20 manufacturers across 4 continents; ranging from the well-known multinational brands to specialist private labelling firms. We can supply the glass as quenched glass pieces (known as frit in our industry) or as a spray-dried powder.

Particle size is entirely the choice of the customer, we currently produce powders with D50 values as high as 10 microns and as low as 0.7 microns. Our clean grinding process is perfect for production of transparent and colourless powders. Spray-drying produces a weakly agglomerated powder that is easier for handling.

Cera Dynamics has ISO 9001:2008 and ISO 14001:2010 certification. Our ISO 9001 quality system has been enhanced to provide sufficient compatibility with our customer's ISO 13485 requirements.

Reactive Glasses

We produce reactive glasses, with fluorine contents up to 25 wt%, for use in traditional glass ionomers, resin-modified glass ionomers, and specialist composite applications. The glass chemistry should ideally be optimised to suit the required final product, and most of our existing customers have their own glass formulation. We offer a small range of example glasses that are available to any customer either for use in a product or as a starting point for development of a bespoke glass.

Inert Glasses

In 2007 we launched our Barium-containing inert glasses for use in composites. We offer two glasses, DF 11 (Barium) and DF 12 (Barium and Zinc). Both are radiopaque and available in a range of particle sizes.

At IDS 2015 we will launch 3 further glasses based on Strontium, Yttrium and Ytterbium. Further details of these glasses will be available soon.

Glass Ceramics

Glass-ceramics are glasses that are manufactured by our usual melting method, quenched to a glassy state. They are supplied as crushed glass pieces or a powder, for further processing and eventual sintering to a ceramic phase.

CDL is developing new technology to widen the melting range achievable in both chemistry and temperature. We are keen to work with manufacturers and researchers to scale-up and commercialise new formulations.


Bioglasses have applications from cosmetics to medical devices. Cera Dynamics is working with several customers in conjunction with academics at UK universities do develop new bioglass formulations and to scale-up glasses from the laboratory to production.
