Primer for preparing a tooth cavity for a composite filling

摘要

The invention relates to the use of a mixture which comprises: a) 1-5 weight % (wt. %) of phosphoric acid; b) 10-90 wt. % of phosphoric acid mono- or di- methacrylates; c) 1-15 wt. % of phosphoric acid trimethacrylates; and d) 3-50 wt. % of diphosphates having between two and four methacrylate ester groups; for the preparation of a composition for preparing a tooth surface for joining with a dental composite material. Using the composition according to the invention, a tooth cavity can be prepared in one step for laying a composite filling. A very high adhesive strength is achieved between the tooth matter and the composite material.
