Titanium Raw Materials Medical Field Application
Sep 12, 2017

First, the application of titanium in the face of treatment

In the human face received serious injury, the local tissue repair surgery with surgical intervention. Titanium alloy has a good biocompatibility and the required strength, so the human facial tissue repair ideal material. Titanium mesh made of skull tray has been widely used in jaw bone reconstruction surgery, and achieved good clinical results.

Second, the application of titanium in the pharmaceutical industry

In the pharmaceutical industry, titanium is mainly used in the production of containers, reactors and heaters. In the process of producing pharmaceuticals, the equipment is often exposed to inorganic acids such as hydrochloric acid, nitric acid and sulfuric acid, organic acids and their salts, and the equipment is damaged due to long-term corrosion. At the same time, the iron pollution caused by steel equipment affects the product quality. Titanium equipment can solve these problems. For example, penicillin esterification kettle, saccharification tank, chloramphenicol film evaporator, dimethyl sulfate cooler, liquid filter, etc., have a precedent for the selection of titanium. Titanium equipment produced by the amount and quality of liquid are constantly improving, and the quality of the Chinese Pharmacopoeia in full compliance with the provisions.

Third, the application of titanium in medical equipment

In the history of the development of surgical instruments, the first generation of surgical instruments made of carbon steel, due to carbon steel equipment after plating performance can not meet the clinical requirements were eliminated. The second generation of austenite, ferrite and martensitic stainless steel surgical instruments, but the stainless steel composition of chromium toxicity, off the chrome layer has a certain impact on the human body, therefore, the emergence of the third generation - titanium surgical instruments. Titanium lightweight high strength, making it particularly suitable for microsurgery. Titanium is resistant to corrosion, good elasticity, no deformation, etc., repeated cleaning and disinfection of the surface quality are not affected; non-magnetic, can exclude the tiny, sensitive implantation of electronic equipment damage threat, these advantages make titanium surgery equipment The more widely Titanium has been used to make surgical blades, hemostats, scissors, electric bone drill, tweezers and so on. In the medical device titanium tube suture needle, sternal suture line, one of the heart surgical instruments oxygen filter, electrocardiogram machine with titanium electrode, in vitro culture machine in the titanium culture device; medical ultrasonic grinder probe, Blood transport box automatic controller, and titanium surgery for ophthalmic surgery.

Fourth, titanium and titanium alloy dental applications

The metal used in dental surgery, from the twentieth century, twenty years of amalgam and metal crown, etc., the sixties mainly use gold, silver, palladium alloy, after the seventies stainless steel teeth for permanent and removable equipment The most commonly used materials, nineties titanium casting technology to promote the use of. Dental use titanium casting machine Casting with high dimensional accuracy, no bubbles and shrinkage and other characteristics In the human body for hard tissue repair of metal materials, titanium elastic modulus and human tissue closest, which can reduce the metal implants and bone Organizational mechanical incompatibility. The thermal conductivity of titanium is the lowest of all metal materials for dental restoration, and the low thermal conductivity can reduce the thermal stimulation of dental pulp teeth and is important for dental restoration. Titanium inlay, the crown, etc. with the protection of pulp, to avoid the role of hot and cold stimulation. Dental titanium in the material, the original mostly titanium, but its strength is insufficient, difficult to grind, there is poor wear resistance, easy to produce casting defects and quality instability and so on. Ti-6Al-4N alloy is the most commonly used, but Ti-6Al-7Nb alloy has the advantages of good corrosion resistance, The human body is basically harmless, but also has a strong plastic, excellent grinding and other advantages, has been recognized by the ASTM standards. At present, titanium can be used as crown, crown nail, fixed bridge, porcelain bridge, adhesive bridge, denture clasp, base, connecting device and strengthening device, almost denture all metal parts can be made of titanium. Titanium alloy porcelain teeth can be a good recovery of the tooth shape and function, and high strength, beautiful appearance, color and stability, smooth surface, wear resistance, corrosion resistance, is a permanent repair body, apply to all fixed teeth, In particular, it is good biocompatibility, sensitive to nickel ions are more suitable, has been widely used in the restoration of teeth.
