Patent
CA 2256752
The invention discloses a polymer containing hydrogen atoms with the required mechanical and chemical properties, characterised in that the hydrogen atoms at the polymer surface are partially replaced by fluorine atoms, and groupings: -CF, -CF¿2? -CF¿3?, -OH, -COOH, -C=O, -OOH, -NH¿2?, -C=NH or -CONH¿2?. Such polymers enable the improvement of prosthesis retention and/or limitation of dentobacterial plaque.
Prothèse dentaire composée d'un polymère contenant des atomes d'hydrogène et ayant les qualités mécaniques et chimiques requises, caractérisée en ce que les atomes d'hydrogène à la surface dudit polymère sont remplacés partiellement par des atomes de fluor, des groupements -CF, -CF2 -CF3, -OH, - COOH, -C=O, -OOH, -NH2, -C=NH ou -CONH2. De tels polymères permettent d'améliorer la rétention des prothèses et/ou de limiter le développement de la plaque dentaire.
