A calcium phosphate-synthetic resin composite body 3 produced by pressing a calcium phosphate block 200 (or a calcium phosphate block and calcium phosphate particles 100), and synthetic resin particles, (I Fig 1B) which are at least partially cross-linked in advance, and uncross-linked, synthetic resin particles (II Fig 1B) while heating, the calcium phosphate block being exposed on at least part of the surface of the composite body. The above composite body is produced by a method comprising the steps of (a) introducing the calcium phosphate block (or a calcium phosphate block and calcium phosphate particles), the synthetic resin particles I and II into a cavity of a forming die such that the calcium phosphate block is present on at least part of the surface of the composite body, and that the synthetic resin particles surround the calcium phosphate particles, if any; and (b) pressing them in the cavity of the forming die while heating, so that the synthetic resin particles are bonded to each other. The resulting phosphate-synthetic resin composite body has a high biocompatibility and may be utilized for biomaterials such as artificial dental roots, bone reinforcements and dental cements. |
