Definitions
- Dental composition based on a crosslinkable and / or thermally polymerizable functionalized silicone.
- the field of the invention is that of dental compositions. More specifically, the dental compositions developed in the context of the present invention are based on crosslinkable and / or polymerizable functionalized silicone, and can be used for the production of dental prostheses, artificial teeth and dental restorative materials.
- the object of the present invention is to provide new dental compositions based on silicone which do not have the drawbacks of the prior art.
- These new dental compositions which can be polymerized and / or crosslinked in the oral environment, have markedly improved qualities, in particular with regard to the very marked reduction in the phenomenon of withdrawal of the materials and prostheses obtained from said compositions.
- These new dental compositions are particularly interesting in terms of reactivity; they are crosslinkable and / or polymerizable thermally, which makes it possible to use conventional crosslinking / polymerization methods and moreover at temperatures below 150 ° C.
- This reactivity is notably due to the presence of a new type of initiator based on boron derivative; indeed, it is active at low concentration and advantageously requires only small amounts of energy to effect crosslinking / polymerization.
- the claimed dental compositions therefore prove to be particularly advantageous in terms of effectiveness in use and in terms of profitability and cost for industrial processes.
