Recent years have seen metal-related allergies become an increasing problem. Allergy to orthodontic materials has been reported. Therefore, the need for countermeasures to allergies to orthodontic metallic materials has increased. Also, there is a possibility that metal elements are included in the nonmetallic materials. However, the components of nonmetallic orthodontic materials are not being examined. We analysed nonmetallic orthodontic materials for metal elements using an X-ray fluorescence spectroscope. It was found that a small amount of metal element was included in nonmetallic materials. When the patient with a metal allergy is treated, a sufficient examination of the nonmetallic materials is also necessary.
