Induced magnetic moment in different orthodontic brackets inside a 1.5 T MRI scanner. The magnetic moment of individual stand-alone bracket or bracket on dental band was measured one at a time (ref.¹³) with a precision better than 10⁻⁴ A·m². (A) Total magnetic moment of 20 non molar brackets (upper, lower, right and left central incisor, lateral incisor, canine, 1st premolar, 2^nd premolar) (ref.¹³). (B) Total magnetic moment of 8 molar (upper, lower, right, left 1st and 2^nd molar) brackets or brackets on bands. Data for the left 3 columns are from ref.¹³.
