CONCLUSIONS
Wires of the same materials, dimensions, and manufacturer but from different production lots do not always have similar mechanical properties. Differ- ences in interlot variations exist between manufacturers of CuNiTi archwires. Improvements should be made in the manufacturing process of archwires to provide clini- cians with CuNiTi archwires that have consistent me- chanical properties.
