Inquiry (采购产品): biocompatibily We are an orthodontic lab and have a request from a doctor to provide a 300 series stainless orthodontic appliance for a patient with a severe nickel sensitivity. We understand that Tin and some related coatings are safe and biocompatible, but we need to know if the coating will completely seal-in the stainless base metal so that ppm of elemental nickel will not enter the saliva. Need to discuss.
