BONE COUPLING AGENT, LAYERED ADHESIVE SYSTEM AND METHOD FOR MAKING SAID COUPLING AGENT

摘要

The invention concerns a novel coupling agent which hardens fast as it is photochemically polymerized, for an efficient adherence between the bone cement and the bone surface during endoprosthetic implant grafting. According to the invention, said coupling agent contains an initiator consisting for example of HEMA, UDMA, GM and/or 4-META and a binder which can consist for example of bisGMA, TEGDMA, poly-EGDMA and/or UDMA or a mixture of said constituents. The binder also is photochemically hardened. The bone surface is treated with a conditioner, a weak acid, which can be mixed with the coupling agent as constituent.
