Dr. Mark Kleive demonstrates fabrication of an acrylic shell for an anatomic (Tanner) appliance. In this video, the acrylic is now ready to remove from the former and be moved to the articulator. Once placed over the lower model, it is important to trim and shape the acrylic to minimize adjustment after it is set. It is also imperative to imprint the acrylic with certain occlusal landmarks that allow for proper adjustment of the occlusal surface of the acrylic.
