Patent

CA 2207351

The invention relates to dental materials based on wax-like polymerizable substances. The dental materials contain (a) 0 to 70 wt.% of at least one polymerizable monomer and/or oligomer; (b) 0.1 to 5 wt.% of at least one polymerization initiator; (c) 0 to 60 wt.% of one or more fillers, (d) at least 20 wt.% of the wax-like polymerizable substance. They can be kneaded at room temperature and can be modelled in non-polymerized state without additional heating, like conventional waxes. On polymerization, the wax component is covalently incorporated into the polymer. The dental materials are suitable for producing temporary and permanent dental prostheses.

L'invention concerne des produits dentaires à base de substances polymérisables semblables à la cire. Les produits dentaires contiennent (a) de 0 à 70 % en poids d'au moins un monomère et/ou un oligomère polymérisable; (b) de 0,1 à 5 % en poids d'au moins un initiateur de polymérisation; (c) de 0 à 60 % en poids d'une charge ou plus, (d) d'au moins 20 % en poids d'une substance semblable à la cire polymérisable. Ces produits peuvent être malaxés à la température de la pièce et peuvent être modelés à l'état non polymérisé sans chauffage additionnel comme les cires traditionnelles. Au moment de la polymérisation, le constituant cireux est incorporé par liaison covalente dans le polymère. Ces produits dentaires conviennent pour la fabrication de prosthèses dentaires temporaires et permanentes.
