Abstract:
A method of manufacturing a patterned retarder includes forming a retarder material layer by applying a retarder material to a substrate; drying the retarder material layer at a first temperature; exposing the retarder material layer to linearly-polarized UV, wherein the retarder material layer has an optical anisotropic property; and heat treating the retarder material layer at a second temperature higher than the first temperature to increase the optical anisotropic property of the retarder material layer.

Abstract:
The present invention relates to a disposable edentulous tray and a method for producing a denture using the same and, particularly, to a new form of a disposable edentulous tray and a method for producing a complete denture using the same, the disposable edentulous tray being capable of: simplifying the operating process of the complete denture for a patient in an edentulous state (the state of having no teeth) by using the disposable edentulous tray in a most similar form to the gum condition of the patient; acquiring an accurate impression; and resolving patient discomfort by simplifying manufacturing steps and thus reducing the number of patient hospital visit days
