The invention relates to a one-component self-adhesive composition for dental use comprising radically polymerizable component(s) with an acidic moiety as component A, radically polymerizable component(s) without an acidic moiety as component (B), an oxidizing agent comprising persulfate(s) as component (C), transition metal component(s) as component (D), photoinitiator system(s) as component (E), optionally non acid-reactive filler(s) as component (F), and optionally additive(s) as component (G).

One component self-adhesive dental composition, process of production and use thereof

The invention relates to a polymerizable dental material containing: (a) 3 to 80 wt. % of one or more cationically curable monomers; (b) 3 to 90 wt. % of one or more radio-opaque fillers; (c) 0.01 to 25 wt. % of initiators, retarders and/or accelerators, and; (d) 0 to 25 wt. % of auxiliary agents, whereby the cited percentages each refer to the total weight of the material. Filler (b) is produced by means of a melting method and is selected so that it has a refractive index of n=1.49&#x2013;1.54, so that the viscosity of the polymerizable dental material, after a period of at least 9 months during which it was stored at a temperature ranging from 20 to 25&#xb0; C., has a value of +/&#x2212;50 % of the initial value measured 24 hours after the polymerizable dental material was produced, and so that the polymerizable dental material has a reactivity of the type that, once polymerization is initiated, the amount of the maximum heat flux generated by the dental material equals at least 0.8 mW/mg, and this maximum heat flux is attained within a period of no longer than 60s.
