| 摘要 |
The present invention relates to a new orthodontic bracket, comprising a bracket base 1, characterized in that there is a mesial groove 2 and a distal auxiliary groove 3 in parallel laterally located on the upper and lower sides of the outer surface of bracket base, wherein the said mesial groove 2 and the said distal auxiliary groove 3 have an archwire slot of mesidal groove 2′ and an archwire slot of distal auxiliary groove 3′ which are lateral and parallel, respectively, and the vertical interval between the center lines of the archwire slot 2′ and archwire slot 3′ is 0.086-0.196 inches. The present invention also involves a self-ligating cover of buckle type based on double groove, breaking the restrictions of current self-ligating bracket on the groove archwire size to be inserted. |

1. A new orthodontic bracket, comprising a bracket base (1), characterized in that there is a mesial groove (2) and a distal auxiliary groove (3) in parallel laterally located on the upper and lower sides of the outer surface of bracket base, wherein the said mesial groove (2) and the said distal auxiliary groove (3) have an archwire slot of mesidal groove (2′) and an archwire slot of distal auxiliary groove (3′) which are lateral and parallel, respectively, and the distance between the archwire slot of mesidal groove (2′) and the bracket base is greater than that between the archwire slot of distal auxiliary groove (3′) and the bracket base, and the vertical interval between the lateral center line of the archwire slot of mesidal groove and that of the archwire slot of distal auxiliary groove lateral is 0.086-0.196 inches. |
