GRAPHENE
SELF-CURED RESINS
The incorporation of graphene into acrylic resins is a new strategy to improve their mechanical properties, simultaneously increasing both the elastic modulus and hardness, reducing the appearance of cracks and / or its diffusion, and decreasing the degree of shrinkage and polymerization.
Graphene is ideal for improving the performance of self-curing acrylic resins for candidate dental use, not only for its high tensile strength, low coefficient of thermal expansion, high absorption and lubrication capacity, flexibility and high surface area, but also for its excellent strength / weight ratio.
Acrylic resins are hard, brittle and crystalline polymers, which are used as heat-stable materials since, after curing, they cannot be processed or molded.
Self-cured resins based on polymethyl methacrylate (PMMA) are the most commonly used materials in the dental laboratory. However, they have low impact strength and low transverse and flexural strength, resulting from the formation and propagation of cracks when subjected to mechanical stress.
PROPERTIES OF GRAPHENE
The G-CAM graphene polymer disc, particularly suitable for permanent dental structures is available in different chromatic formats available an extremely natural aesthetic appearance, as well as solving all the physical-chemical and biological mechanical deficiencies, unlike other materials used in the sector.
It has a similar appearance to natural dentition, ideal for areas that are more aesthetic. The G-CAM disc has a wide color range, even in the same piece, extremely natural.
It has a high glass transition temperature (Tg) which prevents softening and distortion during use and cleaning. Keep in mind that although the normal temperature in the mouth is 32-37 ° C, consuming hot drinks (which can be 70 ° C or more) and cleaning the denture in hot or boiling water, subject to these materials to temperatures higher.
Graphene improves the dimensional stability of polymers for dental use, which allows the dental prosthesis not to change over time. This is affected not only by thermal softening mechanisms, but also by the release of internal stresses, incomplete polymerization of the material or water absorption.
Thanks to graphene, G-CAM improves its resistance compared to its weight. The density of the material is low so that the prosthesis is light.
The material also has high electrical conductivity to maintain a healthy oral mucosa and respond normally to heat or cold stimuli.
It is a translucent material that allows high transparency to mimic the natural aesthetics of the tooth, but also allows us to obtain opaque colors to avoid transparency of necrotic stumps or metal pins.
It is a totally waterproof and stable material that does not allow the accumulation of bacterial plaque, as well as closing all pores so that there is no accumulation of dirt or color.
It does not require an interphase process during tooth make-up. There is no danger of breaking or chipping, because the piece’s enamel is resistant to micro-stress.

- The G-CAM disc is chemically inert
- It is insoluble in oral fluids
- It does not absorb water or saliva, so the mechanical properties of the material are not altered and it is completely hygienic
- It does not allow the phenomenon of bimetallism.
The cured material is not irritating or toxic to the patient. The G-CAM disc has passed cytotoxicity and genetic tests conducted by the University of Alcalá and the Valencian Institute of Microbiology (IVAMI)
- In vitro cytotoxicity test. ISO 10993-5: standard 2009. – Bacterial mutation inversion test. ISO 10993-3: 2014 and OECD 471: 1997 standard
- It is antiallergic. Graphene does not allow the growth of bacteria or fungi
- G-CAM incorporates, through a plasma process, disinfectant products with prolonged release over time.
