Definitions
- the present invention relates to a bone substitute material and a method for producing the same.
- This bone substitute material can be suitably used as a repair material for a portion to which a large load is applied such as a femur, a hip joint, a tooth root, and the like. Background technology
- a condition for the artificial material to exhibit the biological activity of binding to bone in a living body is to form a layer of an apatite of the same kind as the inorganic substance of bone on the surface in the living body.
- N a 2 0- C a O- S i 0 2 - P 2 05 glass or sintered hydroxide Apatai preparative (C a 10 (PO 4) 6 (OH) 2), or M g 0- C a 0- S i 0 2 - such as P 2 0 5 based crystallized glass is used.
- These are excellent materials that have the property of forming a layer of apatite of the same type as the inorganic substance of bone on the surface in the living body and directly binding to bone, and have bioactivity.
- titanium and its alloys which have the best biocompatibility among metallic materials, are currently used as alternative materials.
- these metallic materials have great fracture toughness, but require a long time of about 10 years to directly bond with bone.
- the material obtained by this method has both the fracture toughness of titanium and the bioactivity of apatite.
- the manufacturing method using a plasma coat requires (1) an expensive plasma spraying apparatus.
- the composition and crystallinity of the hydroxyapatite formed on the metal substrate surface is controlled because the hydroxyapatite powder, which is a thermal spray material, is temporarily exposed to a high temperature of about 30,000. Is difficult to do.
- the apatite layer is There are problems that it is difficult to strongly adhere to the substrate and it is easy to separate.
- An object of the present invention is to solve such conventional problems and to provide, at a low cost, a bone substitute material which has both the fracture toughness of titanium and the biological activity of apatite, and in which titanium and apatite are firmly adhered. It is in. Disclosure of the invention
- the bone replacement material of the present invention is:
- a substrate comprising titanium Ti or a titanium Ti alloy, and a coating (first coating) containing a titanium oxide phase and an amorphous phase of titanate formed on the surface of the substrate.
- first coating a coating containing a titanium oxide phase and an amorphous phase of titanate formed on the surface of the substrate.
- pure Ti is good in terms of biocompatibility, but in terms of formability, Ti-6 A1-4 V, Ti-5 A1-2.5 Sn, Ti-3 A Alloys such as 1 — 13 V — ll Cr, Ti 1 15 Mo — 5 Nb — 3 Ta, Ti — 6 A 1 — 2 Mo — Ta are good.
- a second coating mainly composed of apatite may be formed on the first coating.
- the concentration of the titanium oxide phase gradually decreases toward the outer surface, It is desirable that the total alkalinium concentration be gradually increased toward the outer surface.
- the thickness of the first coating is preferably about 0.1 to 10 m, and the thickness of the second coating is preferably 1 // m or more.
- the thickness of the first coating is preferably l tzm, and the thickness of the second coating is preferably 10 m.
- a preferred method for producing the bone substitute material as described above is to immerse a substrate made of titanium Ti or titanium ti alloy in an alkali solution and then immerse the substrate in titanium ti or titanium ti alloy. It is characterized by heating to a temperature below the transition temperature. In order to make immersion and heating proceed simultaneously, heating under pressure may be performed during immersion. In addition, following the heat treatment, the substrate may be immersed in an aqueous solution containing calcium Ca and phosphorus P, for example, a simulated body fluid, which has a solubility equal to or higher than the solubility of the apatite.
- the alkaline liquid is preferably an aqueous solution containing at least one of sodium Na + ion, potassium K + ion and calcium Ca 2 + ion.
- Preferred concentrations, temperatures and reaction times of the alkaline solution are 2 to 10 moles, 40 to 70 ⁇ and 1 to 24 hours, respectively.
- the heating temperature is preferably from 300 to 800 ⁇ , particularly preferably from 550 to 650.
- T i 0 2 is an amphoteric substance which reacts also strong acids, with any strong base. Therefore, when a substrate made of titanium Ti or titanium ti alloy is immersed in an alkaline solution, the surface of the substrate becomes amorphous with a concentration gradient that gradually increases from the inside with a small amount of reaction toward the outside with a large amount of reaction. Is produced. Thereafter, the substrate is heated to a temperature equal to or lower than the transition temperature of the titanium Ti or titanium ti alloy for 1 to 24 hours, whereby oxygen is diffused and the thickness of the formed phase is increased.
- a titanium oxide phase and an amorphous aluminum titanate are formed on the surface of the substrate.
- a coating consisting of phases is formed.
- the alkali titanate produced in the intermediate step has a gradual concentration gradient that gradually increases outward in the thickness direction of the film, the titanium oxide phase serving as the starting material of this compound Gradually decreases toward the outside, while the total concentration of alkali ions (Na + , K + , Ca 2 +, etc.) contained in the amorphous alkali titanate phase, which is the product, It gradually increases toward. Since the concentration changes at such a gentle gradient, the interface between the substrate and the coating and the interface between each phase in the coating are firmly adhered.
- the substrate is immersed in a separately prepared titania gel, a gel that easily binds to the bone is formed on the surface of Ti, but this is different from the fact that the bonding force between the Ti and the gel layer is weak and it is easy to peel off.
- the outermost surface is rich in alkali ions, the alkali ions are exchanged for hydrogen ions in the simulated body fluid or body fluid, and a titanium hydroxide phase that easily reacts with calcium Ca and phosphorus P is generated.
- aqueous solutions and body fluids containing calcium C a and phosphorus P having an apatite solubility or higher contain an apatite-forming component in excess of the apatite solubility, and therefore have the ability to grow apatite crystals.
- the activation energy for crystal nucleation is high, it alone becomes a barrier and lacks the ability to form apatite nuclei alone.
- an amorphous titanium hydroxide phase formed by hydration of titanium oxide is highly reactive because it is amorphous. Thus, it reacts with osteogenic components in body fluids to form apatite nuclei.
- the apatite nucleus may be formed in advance by immersion in an aqueous solution containing calcium Ca and phosphorus P having a solubility equal to or higher than the apatite solubility, preferably in a simulated body fluid.
- an aqueous solution containing calcium Ca and phosphorus P having a solubility equal to or higher than the apatite solubility preferably in a simulated body fluid.
- those treated with a simulated bodily fluid having an ion concentration close to that of the bodily fluid can easily bind to bone because the composition and structure of the apatite formed on the surface are similar to the composition and structure of the bone apatite. Because it is.
- the temperature of the heat treatment is less than 300, the air does not diffuse and the supply of oxygen is insufficient, so that the thickness of the first coating does not increase and the ability to form an apatite on the surface in the body is poor.
- it exceeds 800 the transition temperature of T i is reached, which is not preferable. This is because the mechanical strength of the base is deteriorated when the Ti or titanium Ti alloy of the base is transformed.
- FIG. 1 is a view showing the results of thin-film X-ray diffraction when a specimen heated at 600 ° C. after being immersed in a Na0H solution was immersed in a simulated body fluid.
- the Ti metal plate was placed in a furnace and heated to 400, 500, 600, or 800 at a rate of 5 ° C. Z min and kept at each temperature for 1 hour.
- the structural change of the titanium metal surface after each of the above treatments was examined by thin film X-ray diffraction and scanning electron microscope-energy dispersive X-ray analysis (SEM-EDX).
- the amorphous layer on the specimen heat-treated at 600 had a thickness of about and uniformly covered the surface of the titanium metal. Also, according to SEM-EDX of the cross section of the specimen heat-treated at 600 after immersion in the KOH solution, the potassium concentration gradually decreased from the surface to the inside in the amorphous layer. Was observed.
- a titanium oxide phase (rutile type, anatase type) and an amorphous phase of alkali titanate are formed on the surface of the metal plate heated at 400-600. It had been. The front surface of the heated T i metal plate 8 0 0, the amorphous phase of the alkali titanate disappears, N a 2 T i 5 0 crystalline phase was observed instead.
- CI - 1 4 8, HC 0 3 - 4. 2 ⁇ ⁇ - 1.
- FIG. 1 shows the results of thin-film X-ray diffraction when a specimen that had been immersed in a NaOH solution and then heat-treated at 600 was immersed in a simulated body fluid.
- apatite began to form on the surface, and three weeks later, the apatite layer grew and covered the surface, and almost no titanium metal peak was observed.
- an apatite layer having a thickness of 5 to 10 ⁇ m was uniformly formed on the surface of the titanium metal.
- Specimens heat-treated at 400 ° C. and 500 had the same tendency.
- the bone substitute material and the method for producing the same according to the present invention have the above-described configuration, they have the following remarkable effects. In other words, heating is only required after immersing the Ti metal in the alkaline solution, so no expensive equipment is required.
- an apatite of the same quality as the bone mineral is naturally formed on its surface, through which it is firmly bound to the bone.
- an apatite of the same quality as the bone mineral is formed on its surface. It binds more firmly to bones. ⁇ Excellent in biological freshness.
