0.35 mm how much is the titanium titanium wire?
Under normal circumstances, the surface layer of titanium oxidation acts as a barrier, so that Ni-Ti alloy has good biocompatibility. The surface layer of TiXOy and TixNiOy can inhibit the release of Ni
Through the results of different archwire attenuation experiments, it was found that the amplitude of vibration of stainless steel wire was larger than that of superelastic nickel-titanium wire. The initial vibration amplitude of super-elastic Ni-Ti arch wire was only half of that of stainless steel wire. The health of the teeth is important, and the traditional arch wire, such as stainless steel wire, has a tendency to increase the absorption of the root.
Due to chewing and night molars for the arch wire caused by the greater the vibration, the greater the damage to the root and periodontal tissue
Nickel-titanium shape memory alloy special chemical composition, that is, this is a kind of nickel and titanium and other atomic alloys, containing about 50% of the nickel, and known nickel has carcinogenic and carcinogenic effects
At present, from the medical point of view of nickel-titanium alloy is good for the human body, should not be bad for human health.
