Purpose: To compare discomfort level felt when the traditional nickel titanium (NiTi) archwire and the copper nickel titanium (CuNiTi) archwire are used in fixed orthodontic appliance to alleviate mandibular anterior teeth crowding.

Methodology: A sample of 24 patients were randomly allocated with control; nickel titanium and intervention; copper nickel-titanium (Cu NiTi) archwire groups. Each archwire was ligated with a ligature wire for 10 weeks follow up. The primary outcome was measuring the pain level at first, second, third and seventh days of the study time through using ‘Numeric Pain Rating Scale”.

Results: The pain threshold scores between the two groups did not differ statistically significantly.

Conclusion: Patients using premium Tanzo copper nickel titanium (Cu-NiTi) archwires and Nickel titanium (NiTi) archwires experienced similar levels of pain.
