No study has been carried out to compare this relatively new archwires to other popular OSSA already in the market. Aim: The aim of this study was to compare the mechanical properties of Damon 0.019” x 0.025” OSSA with Standard Ormco and 3M archwires. Method: 30 preformed archwires of each type (Standard Ormco, 3M and Damon) were tested in the as-received condition. Tensile tests were performed on a Instron Universal Testing Machine with an inter-crosshead span of 10mm. Data were obtained using Bluehill software for maximum load, automatic modulus, 0.1% yield strength and Young’s modulus. Results: For maximum load, there was no difference between Damon (Mean 659.8 ± 26.6N) and 3M (Mean 668.4 ± 9.1N), but both Damon and 3M were statistically superior compared to Standard Ormco (Mean 611.9 ± 23.2N). With respect to automatic modulus, Damon (Mean 41786.0 ± 5104.2MPa) was proven to be statistically inferior to both Standard Ormco (Mean 47318.2 ± 6106.2MPa) and 3M (Mean 49897.6 ± 3286.1MPa). For the 0.1% yield strength, there was no difference between Damon (Mean 2150.1 ± 88.6MPa) and 3M (Mean 2178.8 ± 29.6MPa), but both Damon and 3M were statistically superior compared to Standard Ormco (Mean 1990.8 ± 74.5MPa). With regard to the Young’s modulus, Damon (Mean 40598.3 ± 5077.4MPa) was proven to be statistically inferior to both Standard Ormco (Mean 44910.9 ± 5463.4MPa) and 3M (Mean 47500.7 ± 3431.6MPa). Conclusion Damon 0.019” x 0.025” OSSA were proven to be similar to 3M in maximum load and 0.1% yield strength. As for Young’s and Automatic Modulus, Damon was proven to be statistically inferior to 3M and Standard Ormco. 3M was proven to be superior in all parameters.
