An apparatus, a system and a method provide automatic tooth straightening. An appliance may be placed on teeth to straighten teeth. The appliance or series of appliances may be made to fit a particular patient. The appliance may fit onto the teeth that do not require straightening using a section that may be made from relatively stiff material. The erupted teeth that require straightening may be straightened with a softer more resilient material. The unerupted teeth may be guided into the mouth by another portion of the appliance that is preformed with predicted sizes and shapes of teeth determined from sizes of other erupted adult teeth and shapes from anatomical standards. A hard stiffer inner shell and/or a stiffer isthmus having a softer material is overlayed to directly contact the teeth.
