Abstract
The invention relates to a method for the production of an adhesive and an adhesive kit for joining similar or different metal surfaces or ceramics, especially in the field of biomedicine. The objective of the invention is to avoid polymerization-linked by-products and disadvantageous effects, in addition to enabling a temporary biocompatible bond between metal and metal or metal and ceramics. The inventive method consist in using a monomer-free polymethylmethacrylate which is mixed with a suitable, non-toxic solvent and a bioactive vitreous-crystalline material with a particle size ranging from 0.05 20.mu., consisting of 15 45 wt. % CaO, 40 45 wt. % P.sub.2O.sub.5, 10 40 wt. % ZrO.sub.2 and 0.7 3.5 wt. % fluoride, having apatite and calcium zircon phosphate as main crystal phases and a glass phase as an auxiliary component until a flowable mixture is obtained. The invention also relates to an adhesive kit consisting of said components. Sufficient amounts of resistance are obtained for a temporary bond, enabling the bond to be neutralized when desired.
