ABSTRACT:
A dental treatment tray used to provide a desired treatment is injection molded from a composition that includes at least one thermoplastic resin and at least plasticizer. The plasticized thermoplastic resin permits the dental treatment tray to be injection molded even while having a wall thickness less than about 0.015 inch. The plasticizer increases the melt flow index of the thermoplastic resin while in a molten state, which facilitates complete filling of the mold cavity by the thermoplastic resin. The plasticizer also softens the thermoplastic polymer while in a solidified state in order to yield a dental tray that is even more flexible and comfortable for the user to wear.
