Titanium in The Medical Field

The use of titanium metal in the medical field is also relatively widespread. Firstly, it is used extensively in dental restoration and reconstruction. Because titanium has good corrosion resistance, human body affinity, the human body does not produce allergies when in contact with it, coupled with extremely low thermal conductivity, can reduce the thermal stimulation of the dental pulp of the crown teeth, and therefore doubly favoured by dentists. From the 1980s onwards, developed countries have used titanium to repair teeth, this kind of denture made of titanium alloy, to restore the function of the teeth have a great help, it is beautiful appearance, colour and human teeth do not have a big difference, and luster, abrasion, corrosion resistance are in line with the requirements of the permanent restoration of the body, by the people's popularity, at present, the study of titanium and titanium alloys has become a dental application of alloys of the hot issues One of them. Secondly, it can also be applied in human bone°, tissue transplantation and reconstruction. In a large number of surgical operations, the human body's bones, tissue transplantation, reconstruction and connection is often the case. To become a substitute material for human bone and joints should have the following basic properties: lightweight, high strength, biocompatibility, corrosion resistance, and implanted in the body of the tissue reaction can not be caused by the deterioration of the material, but also in the expected life of the function must be maintained, in the fatigue, wear and tear, corrosion, and impact loading will not be deteriorated, and titanium and titanium metal, the physical and chemical properties of titanium are in line with the above performance requirements. Therefore, the use of titanium to make artificial bones can not only meet the above requirements to go, and according to experiments show that human cells can be regenerated on the bone and growth. At present, titanium has been widely used in artificial bone joints, artificial bone, joint foot plate, broken bone fixator, intramedullary nails, artificial heart valves, skull and other clinical replacement and repair, practice has proved that titanium application effect is good, at present has not been found to have a significant rejection of cases with the human body. Thirdly, titanium has long been a favourite tool for doctors to make surgical instruments. Since the development of surgical instruments, titanium has become the protagonist. The first generation of surgical instruments are mainly made of carbon steel, the second generation of austenitic, ferritic Q and martensitic stainless steel ° surgical instruments, but people many times after the clinical use of stainless steel has been found to be toxic, will be infected wounds, and made of titanium instruments can effectively avoid the above problems, so the third generation of surgical instruments - titanium surgical instruments. Titanium surgical instruments Y, it is lightweight, corrosion-resistant, elasticity and softness for the first and second generation of surgical instruments are not as good, and can be repeatedly scrubbed after the operation, so the surgical instruments made of titanium are highly favoured by surgeons.
