简要总结
Evaluate the efficiency of using copper nickel titanium (CuNiTi) arch wire on the initial stage of leveling and alignment regarding their rate of alignment in comparison to Conventional Nickel Titanium arch wire (NiTi) by Measuring the amount and rate of alignment achieved every 2 weeks for a period of 2 months.
.
详细描述
Leveling and alignment is the first stage in fixed orthodontic treatment, performed for every patient. Copper nickel titanium (CuNiTi) was modified from conventional nickel titanium (NiTi) to stabilize the super elasticity properties of the initial nickel titanium (NiTi) arch wire against cyclic deformation. The addition of copper to traditional nickel titanium enhances thermal reactive properties and consistency of forces.so the aim of the study is to Evaluate the efficiency of using copper nickel titanium (CuNiTi) arch wire on the initial stage of leveling and alignment regarding their rate of alignment.
