PURPOSE:To provide the title adhesive which can bond ceramic materials firmly to metallic materials and has excellent biocempatibility, by incorporating a specified filler in a resin component. CONSTITUTION:30-75wt% hydroxyapatite having an average particle size of 0.5-50mum as a filler is added to a resin component consisting of a polymn. initiator, a sensitizer, a polymn. inhibitor, an ultraviolet absorber, a resin or a monomer, etc. to obtain an adhesive 4 for ceramics. A metallic core material 3 is inserted into a hole 2 formed at the central part of a dental root 1 composed of hydroxyapatite buried in an alveolus and the root 1 is bonded to the core material 3 by means of the adhesive 4. A shaft 7 provided at the bottom of a metallic frustoconical support 6 is inserted into a hole 5 formed in the core material 3 and fixed thereto by the adhesive 4. The support 6 is covered with a crown 8 and fixed. |
