Important Information on Plastics
Invisalign© aligners and Vivera retainers are produced from USP Class VI medical grade, high molecular weight, polyurethane resins. Tests have been conducted to determine the biocompatibility of the material of the aligners and retainers and show the material to be biocompatible and pass all applicable regulatory requirements and thresholds for human wear in the mouth. Aligners and retainers do not contain Bisphenol-A nor phthalate plasticizers. Of course, as with any medical device, you should consult with your health professional about your aligner or retainer treatment and any applicable risks of use.
