Titanium electrode electrode titanium sheet grade 5 system in medical apparatus and instruments vascular suture needle, sternum sutures, cardiac surgical instruments, one of the oxygen filter of titanium electrode welding rod filter, electrocardiogram machine using titanium electrode welding electrodes, in vitro cultivation machine using titanium electrode electrode do; Medical ultrasound mill probe, blood transportation box automatic controller, and used in eye surgery titanium electrode welding equipment, such as the current usage are good. Because the titanium electrode has good corrosion resistance and affinity, human body and the metal hypersensitivity and specific strength is considered suitable for application in the field of dentistry. Use of metal dental surgery, from the 1920 s of amalgam and metal crowns, 60 s mainly using gold, silver, palladium alloy, stainless steel after seventy s has become a permanent or removable devices orthodontics with the most commonly used material, titanium electrode in the ninety s casting technology popularization and application. Dental use precision casting machine casting titanium electrode has the characteristics of high dimensional accuracy, no bubble, and shrinkage cavity in metal titanium plate gr7 materials used in the human body hard tissue repair, the elastic modulus of titanium electrode with human tissue is the most close, it can relieve the mechanical inadaptability between metal implants and bone tissue. Titanium electrode in the thermal conductivity is the lowest of all dental repair with metal materials, low thermal conductivity can reduce with crown tooth pulp thermal stimulation, it is important for tooth repair.
Titanium electrode system inlay, full titanium exhaust tubing crown and so has the protection of dental pulp, avoid the effect of hot and cold stimulation. Dental titanium electrode in terms of material, the original more for pure titanium welding rod, but its strength is insufficient, it is difficult to grind, existence abrasion resistance is poor, easy to produce the casting defects and the quality is not stable, etc. Titanium electrode alloy high strength, is the most commonly used Ti 6 al 4 V alloy, harmful to human 6al4v titanium bar body, but as a result of metal V switch to Nb instead of V, Ti successful development - 6, 7 Nb alloy, it has excellent corrosion resistance, and basic harmless to human body, but also has good plasticity strong, the abrasive resistance and other advantages, has made the ASTM standard approval. The hyperelastic Ti - Ni alloy is applied to the teeth straightening. Since the 1980 s developed countries began to study the application of titanium electrode in oral cavity repair, first used in dental implants, and later used for denture stents, and tooth crown bridge is silk, the titanium electrode for dental crowns, nail nickel titanium wire crown and fixed bridge, bridge PFM bridge, binding, denture card ring, underpinning, connection device and strengthen device, denture nearly all the metal parts can be made with titanium electrode.
