Abstract: This invention is a dynamic orthodontic bracket system which allows brackets to be adjusted for particular angulations required for each individual tooth of a patient, while the frames are continuously attached to tooth surface. The orthodontist manually adjusts the relationship of a bracket and a frame during treatment eliminating the necessity of a full repositioning of all components. The bracket is positioned such that it can move in various directions to achieve a proper angulation for tooth repositioning. The base of the bracket and the interior surface of the frame can be textured to provide friction and secure the components once positioned for proper tooth movement. The exterior of the frame can also be textured to provide more secure attachment to the surface of the tooth. This system will lead to lower treatment cost and quicker adjustments of the orthodontic bracket system.
