A handle for removably attaching to a moldable orthosis positions the orthosis in boiling water. The handle includes an arm with an oral orthosis engaging member at one end. The engaging member includes one of a tab or slot which removably engages the oral orthosis. In a preferred embodiment, the arm further includes a hook-like member for supporting the oral orthosis on the rim of a container of boiling water during the molding process. In one embodiment, the handle forms the cover of a storage case for the orthosis.
