PROBLEM TO BE SOLVED: To provide an orthodontic bracket in which an opening/closing block steps out of the way of inserting an orthodontic wire in a wire insertion groove of the bracket, in which construction is simple to make miniaturization possible, and in which lid closing operation of an engaging piece is easy.SOLUTION: An orthodontic bracket of the present invention includes: a tooth abutment plate that is connectable to a tooth flank through an adhesive; a wire insertion block that is roughly U shaped in the cross section of the upper opening; and an opening/closing block that is freely openably/closeably connected transversely to the insertion block through a vertical pivot and that is roughly U shaped in the cross section. The bracket is characterized in that, in opening/closing through the vertical pivot of the opening/closing block, the roughly U shaped upper and lower pieces of the opening/closing block is configured to vertically hold the wire insertion block, thereby enabling the upper opening to be opened/closed in the wire insertion block. |
