Description
Technical field
What the present invention relates to is a kind of titanium alloy, the present invention also relates to a kind of preparation method of titanium alloy.Specifically a kind of no-toxicity medical titanium alloy that is used for Oral Repair and preparation method thereof.
Background technology
Tooth and damaged person 3.7 hundred million people lose in China at present, 3,000,000,000 of carious teeth, and the dentistry of needs of patients more than 100,000,000 implanted treatment, and aging population makes increasing to the demand of oral cavity material.The bio-medical metallic substance is widely used in the repair and reconstruction and the orthopaedic treatment of dental functions forfeiture, and Fig. 1 has summed up the mechanical property and the purposes of the typical dental prosthetic metal of using clinically at present.Yet there are the potential carcinogenesis in Ni element and Cr element in Ni-Cr alloy, Co-Cr alloy, Ni-Ti alloy and the stainless steel, cause that very easily the human allergy reacts (dry, oral cavity burning sensation, gum are itched, oral mucosa pathology); The cost of Au alloy is very high, and patient's economical load is heavier.The density of titanium or titanium alloy less (be about iron-based and cobalt base alloy half), be used for the oral cavity and do not have foreign body sensation, the specific tenacity height, Young's modulus is low, biomechanical property is good, biocompatibility, erosion resistance and anti-fatigue performance are better than stainless steel and cobalt base alloy, and acids food is not produced spoiled phenomenon, have become the most promising medical metal material.Yet titanium or titanium alloy is used for dental field and still has some deficiency.The fusing point of pure titanium higher (1667 ℃), at high temperature very active, be used for dentistry melting difficulty; Its tensile strength is low, and wear resistance is relatively poor, and being used for the removable denture mechanical strength can not meet the demands, and is used for fixing artificial tooth wear resistance deficiency; There are problems such as poor rigidity, yielding, difficult processing in addition.The mechanical property of Ti-6Al-4V alloy can meet design requirement, yet V and Al have very strong toxic effect, and V mainly influences the ferment system, and Al mainly influences brain and causes the alzheimer encephalomyelopathy, also can cause osteoporosis etc.Casting secondary pure titanium and Ti-6Al-4V alloy are directly used in design (as the screw thread that is connected seam, planting body of planting body and base station, surface micropore etc.) its fatigue strength and the tensile strength deficiency of the tiny parts of planting body, can not be applied to clinical.
Ideal used for stomatological repair titanium alloy should have following characteristics: excellent biocompatibility, intensity and plasticity, suitable hardness and good wear resistance, lower fusing point and excellent castability, lower density etc. to be to adapt to the requirement that specific clinical oral application background and dental laboratory are made preferably.At present both at home and abroad the various new titanium alloy of exploitation select the elements such as Mo, Nb, Zr, Ta, Hf, Pd, Pt of good biocompatibility as alloy element in a large number, the fusing point of alloy is very high, density is very big, homogeneity of ingredients control to molten alloy has proposed higher requirement, relatively more difficult when particularly carrying out casting processing as dental material, be not suitable for use in dental alloy.People adopt the method for alloying to design a series of novel oral cavities titanium alloy: Ti-Cu, Ti-Ag, Ti-Au, Ti-Co, Ti-Cr, Ti-Zr alloy etc.By the retrieval to existing document, existing titanium and germanium are used for the report (Chinese patent publication number: CN201285479 and CN201308719) of biomedical sector, yet it only is titanium particle and germanium particulate mechanical bond rather than metallurgical binding; Add a spot of Ge and in Nb base alloy, form superconductor (Kitada, M. (1973). " Supercondctivity of Nb-Ti-Ge Alloys. " J Jap Inst Metals 37 (1): 104-109. and Kitada, M.and T.Doi (1972). " Applied magnetic Field vs Critical Current Density Characteristics of Superconducting Nb-Ti-Zr and Nb-Ti-Ge Sheets. " J Jap Inst Met 36 (9): 891-896.); Join in the Ti-Nb base alloy and can regulate the alloy (Inamura that the transformation temperature acquisition has shape memory effect, T., Y.Fukui, et al. (2005). " Mechanical properties of Ti-Nb biomedical shape memory alloys containing Ge or Ga. " Materials Science and Engineering C 25 (3): 426-432.); The Ti that adds minute quantity Ge
99.97～99.93Ge
0.03～0.07Has low-temperature superconducting (Jian, W.B., C.Y.Wu, et al. (1996). " Electron-electron interaction and normal-state transport in superconducting Ti-(Sn, Ge) alloys. " Physical Review B-Condensed Matter and Materials Physics 54 (6): 4289-4292.); In addition, also have a large amount of reports about titanium germanium intermetallic compound.Yet existing technical literature is that the research of alloy seldom relates to for Ti-Ge, we are based on pure titanium, adopt the method for alloying to develop and a series ofly can satisfy multi-purpose novel oral cavity Ti-Ge series titanium alloy, based on now proposing the present invention on the basis of our scientific experiment.
Summary of the invention
The object of the present invention is to provide a kind of have nontoxic, mechanical property is adjustable, the adjustable oral cavity multi-usage Ti-Ge of performance of corrosion-resistant, good casting property, good biocompatibility is an alloy.The present invention also aims to provide a kind of preparation method simple, by the adjustment of alloying constituent, the adjustable oral cavity multi-usage Ti-Ge of performance that can satisfy the performance requriements of multiple dental prosthetic alloys such as hat, bridge, denture and planting body is the preparation method of alloy.
