ABSTRACT:
In order to provide an orthodontic bracket having no tie wings, capable of removing drawbacks of prior art brackets, in an orthodontic bracket according to the present invention a main body of the bracket is made of shape memory alloy or resin. Further, in lieu of tie wings, there are disposed nail portions for holding an arch wire in a slot of the bracket. Owing to such a construction, the orthodontic force can act thereon with a high efficiency and the size of the bracket can be reduced. In addition, since the tie wings are unnecessary, accidents due to a cut end of a ligature wire are reduced.
