The invention relates to dentistry and can be used in combination with orthodontic brackets and arches in the complex orthodontic treatment for correcting the anomalous position of the teeth. An orthodontic ligature contains the elements for the arch fixation in the groove of the bracket made of the ligature wire. The fixation elements are made as two loops of different shapes that are interconnected. The lesser loop is generated by twisting and point welding or only point welding of the ligature wire in the lower part of this loop. The U-shaped larger loop has the free ends capable of being connected by twisting providing for the closed shape. The diameter of the ligature wire is 0.30-. |
