Abstract

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).

Description

technical field [0001] The present invention relates to a one-component self-adhesive dental composition comprising a photoinitiator system, an oxidizing agent and a copper compound. The compositions are useful in a variety of dental applications. Background technique [0002] Dental composites are well known in dentistry and are widely used as restorative materials (filling composites) or as cements (resin cements) in the field of restorative dentistry. In general, the composite material is hydrophobic in nature and contains inorganic filler, (meth)acrylate-based resin matrix and free radical polymerization initiator as main parts of the formulation. [0003] To achieve adhesion to enamel and dentin, composites often require pretreatment of the tooth surface through the use of binders or bonding systems. This can lead to a rather complex and time-consuming procedure. Therefore, attempts were made to develop self-adhesive composites avoiding the use of additional binders / ...
