Which of the following statement is true as far as spring back bending of super-elastic NiTi and non-super elastic NiTI wires is concern?
(A) Spring back in bending is much greater for superelastic NiTi wires than non-superelastic NiTi (B) Spring back in bending is much lesser for superelastic NiTi wires than non-superelastic (C) Spring back in bending is same for superelastic Nill wires as well as non-superelastic NiTi wires (D) No comparison can be made between the spring back in bending of these two wires
(A) Springback—The amount of elastic strain that a metal can recover when loaded to and unloaded from its yield strength; an important property of orthodontic wires.
