The teeth are separated and teeth are placed back in their malooclusion position on a base support. The teeth are moved directly from the malocclusion position to the prescribed ideal form. A tool is provided which can assist in establishing the arch form, placing the brackets on the model teeth in accordance with the desired arch form and determining the wire arch form.
