Development and Application of Biomedical Titanium and Titanium Alloy for Surgical Implant

Ad Details

 Many kinds of Ti-6Al-7Nb alloy implants have been put into clinical application with good results. Another medical titanium alloy, Ti-5Al-2.5Fe, was developed by Germany. Compared with Ti-6Al-4V alloy, vanadium is replaced by cheap and non-toxic iron element. Ti-5Al-2. 5Fe is a medium-strength material, which is equivalent to Ti-6Al-4V in terms of mechanical property,titanium tubing price, toughness and fatigue strength. These two alloys have also been developed in China. Ti-6Al-7Nb and Ti-5Al-2.5Fe alloys have been developed by the joint efforts of Baotai Group Co., Ltd., Beijing Central Research Institute for Nonferrous Metals, Hebei Medical University, Shandong Wendeng Orthopedic Hospital and the Second Orthopedic Medical Equipment Factory of Tianjin Medical Instrument Industry Corporation. The results of biological experiments show that the alloys have good biocompatibility. And can form the good osseointegration with the bone organization, at present domestic by Shanghai Ai Liai metal material limited company and so on unit proxy distribution. 2.2 New Beta Titanium Alloys Since the 1990s, there have been reports about the potential hazards of V and Al elements to human body in titanium alloy implant materials. Therefore, the development of advanced biomedical metal materials with excellent comprehensive mechanical properties and more compatible with human soft and hard tissues and biomechanics, the new β-titanium alloy, has become the focus of biomedical metal materials research. A series of new type β titanium alloys were developed by adding non-toxic elements such as Nb, Ta, Zr,titanium sheet grade 5, Mo and Sn. 2.3 Ti-Ni alloy. Ti-Ni shape memory alloy is a new type of functional material. This kind of functional material has peculiar shape memory effect, superelasticity, fatigue resistance, wear resistance, corrosion resistance and good biocompatibility.  The composite oxide coating was formed on the surface of titanium alloy by anodic oxidation, hydrothermal treatment and heat treatment. The prepared gradient coating has complete crystal form, titanium bar grade 5 ,ti6al4v, and the surface of the gradient coating has high capability of inducing a bone hydroxyapatite layer to form and cell adsorption and proliferation capability, and has good biocompatibility. 2.6 Laser Near-Net Shaping of Surgical Implants Laser near-net shaping technology is a 3D printing manufacturing technology, combined with computer control, which gradually uses high-energy beams to melt titanium alloy powder in the molten pool and process it into specific shapes of orthopaedic implants or dental restorations.The implants produced in China are difficult to meet the market demand, and most of the high-end implants need to be imported from abroad,titanium plate gr7, which has brought unprecedented opportunities and challenges to medical material research units, material manufacturers, medical research institutions and clinical medical experts in China. These units should strengthen cooperation and work hard to achieve the localization of high-end implants for the benefit of the people. To promote the healthy and stable development of China's medical titanium alloy industry. Return to Sohu to see more Responsible Editor:. yunchtitanium.com
