Abstract
A method for forming dental appliance having an ornamental indicia carrier may include forming a polymeric shell, forming a first adhesive layer configured to be adhered to the polymeric shell, the first adhesive layer including a pressure sensitive adhesive layer, forming a first adhesion layer over the first adhesive layer, and applying a colorant between the first adhesion layer and the pressure sensitive adhesive layer.
Claims20
A method for forming ornamental indicia carrier for durably adhering to a dental appliance, the method comprising:
- forming a first adhesive layer comprising a pressure sensitive adhesive layer configured to be adhered to a polymeric shell of the dental appliance and having a plurality of tooth-receiving cavities shaped to receive and resiliently reposition a subject's teeth from a first arrangement toward a second arrangement;
- coupling a first removable protective layer over the pressure sensitive adhesive layer;
- applying a second adhesive layer over the first adhesive layer;
- coupling a second removable protective layer over the second adhesive layer;
- and
- encapsulating a colorant forming an image between the first adhesive layer and the pressure sensitive adhesive layer of the second adhesive layer.
