The world population is nearly 7 billion. According to incomplete statistics, there arenearly 400 million disabled people, 60 million limb disabled people, and 2billion patients with dental diseases. At present, there are only 35 millionpeople implanted with biomaterial devices. The annual number of jointreplacements is about 1.5 million, which is far from the actual needs number ofreplacements.

Therefore,the potential market demand for biomedical materials is huge. As the first
choice of biomedical metal materials - titanium bar and titanium plate demand will also increase, so it is imperative to increase the research and development of medical titanium alloy materials.

Biomedical titanium is an important branch of materials science. It is a new carrier material with technical content and high economic value, which is used for diagnosis, treatment or replacement of human tissues and organs, or to improve their functions. It is a new developing field in materials science. Biomedical titanium bar makes great contribution to the exploration of human life mystery and the guarantee of human health.

Among thebiomedical metal materials, titanium and titanium alloy has become the first choice material with its excellent comprehensive properties in medical implant products. Such as artificial joints, bone trauma products, spinal orthotic fixation systems, dental implants, braces, orthodontic wires, artificial heart valve and interventional
cardiovascular stent. At present, there is no better metal material than titanium alloy for clinical use.

The developed countries and the world-renowned suppliers of implant products attach great importance to the research and development of titanium alloy, and have launched a series of new medical titanium alloy materials, including bionic titanium alloy materials with biological activity. They has done a lot on patent design and development of surface treatment on medical titanium alloy material, give medical titanium alloy material better biological activity to meet the physiological needs of the human body, then to achieve the purpose to let the patients recover earlier.
