Induced magnetic moment in stainless steel components of orthodontic appliances in 1.5 T MRI scanners

Purpose: Most orthodontic appliances are made of stainless steel materials and induce severe magnetic susceptibility artifacts in brain MRI. In an effort for correcting these artifacts, it is important to know the value of induced magnetic moments in all parts of orthodontic appliances. In this study, the induced magnetic moment of stainless steel orthodontic brackets, molar bands, and arch‐wires from several vendors is measured. Methods:...
