Abstract:
1. A method for the production of an adhesive bond between (a) the surface of dental subframes based on polymers comprising polyether ether ketone (PEEK), polyether ketone ketone (PEKK), polyoxymethylene (POM), and/or polyamide and (b) dental composites, by A at least creating retentive anchoring by means of mechanical pre-treatment of the surface of each subframe; wherein the mechanical treatment is carried out by sandblasting; B application of a low viscous, or free-flowing adhesive agent containing a monomer mixture of polymethyl methacrylate, methyl methacrylate, at least one bifunctional methacrylate-based cross-linking monomer, initiator(s), and optionally stabilizers and other additives, wherein the adhesive agent has no solvent and, wherein the adhesive agent has a viscosity of 10-30 mPas at 23° C., including (i) wetting of the surface, (ii) penetration into the retentive anchoring, and (iii) formation of a dispersion layer or a film; C at least partially curing the dispersion layer or the film in step B; and D applying a dental composite or an opaque onto the cured dispersion or film in step C.
