Abstract

The synthesis of self-adhesive polymerizabe monomers and their application as a water containing and a water free self-adhesive dental/medical composite is described. The dental/medical composite comprises a self-adhesive polymerizabe monomer, a polymerizable monomer, an acid-reactive and/or reactive and/or non-reactive filler, a diluent, a polymerization initiator and a stabilizer. As polymerization initiators are used the commonly known thermal initiators, redox initiators and/or photo initiators. The new adhesive dental composite develops adhesion to dentine of about 4 MPa. Fillers of high X-ray absorbance provide radio-opacity values grater than that of the same thickness of aluminium.
