Abstract
An orthodontic appliance (110,400), a system (100) and a method are provided for automatic tooth straightening. The appliance (110,400) may be fabricated manually or by stereolithography using a computer program (106) that formulates a three-dimensional digital model (107). The appliance (110,400) or series of appliances (110,400) may be made to fit a particular patient wherein a portion of the appliance (110,400) may be attached to fully erupted teeth (306) that are substantially straight. The appliance (110,400) may fit onto the teeth (306) that do not require straightening using a section (402) made from a relatively stiff material so that the appliance (110,400) remains in the mouth in a relative constant position. The erupted teeth (302) that require straightening may be straightened with an area (404) of the appliance (110,400) formed of a softer, more resilient material so that fewer appliances may be required than if a stiffer material were used. The unerrupted teeth (304) may be guided into the mouth by another portion (406) of the appliance (110,400) that is performed with predicted sizes and shapes of teeth determined from anatomical standards. The appliance (110,400) may be formed of a hard stiffer inner shell (502) overlaid by a soft outer layer (501).
