ABSTRACT:
Modular orthodontic bracket structure including a pair of releasably interengageable bracket members. One of these members, which forms an outer member, has a relatively high degree of elastic stiffness. This outer member includes ligating posts which define a socket for snap-receiving the other, or inner, member. The inner member has a lower degree of elastic stiffness, and includes a slot for receiving an arch wire. The slot is shaped to define the particular positional orientation of an arch wire received therein so as to effect the transmission of a prescribed force from the wire to the outer bracket member, and then to a tooth.
