A method and apparatus for moving malpositioned teeth to orthodontically correct positions and simultaneously positioning the lower dental arch of a patient relative to the upper dental arches that includes providing braces for securing to the upper and lower arches and providing a four section internal spring loaded telescopic rod for fastening a first end directly or indirectly at or near a lower molar and a second end directly or indirectly at or near an upper molar. The telescopic rod may resiliently urge extensively toward its elongated fully extended position to assist in dento-aveolar movement of the teeth for correcting the bite. The method and apparatus may also include providing an internal spring member for resiliently urging the telescoping rod extensively toward its elongated fully extended position to assist in dento-aveolar movement of the teeth for correcting the bite. |
