Abstract
Abstract A therapeutic or protective appliance formed to fit the surface of a segment of a body coated with a room temperature vulcanized silicone elastomer. The appliance may be made in rigid or flexible form, is reusable and durable, and may be maintained in a hygenic condition easily by washing or other means. Flexible appliances find application in body areas where soft tissue has been removed or disappeared such as disorders of the foot or toes or areas where flexibility is important to body comfort or function, and rigid appliances may be used as post-operative or other support or protective splints or appliances.
