Evaluating the Mechanical Properties of Zinc-Coated Stainless Steel Orthodontic Wires Using Physical Vapor Deposition

Table 1

Mean ± SD of three-point bending strength values (N) in coated and uncoated wires.

Groups	Coated	Uncoated
1 mm	18.75 ± 0.32^b,A	12.37 ± 0.43^c,B
2 mm	32.72 ± 7.76^a,A	22.70 ± 0.67^b,B
3 mm	33.92 ± 0.42^a,A	27.02 ± 0.44^a,B
