Abstract
An orthodontic bracket is described and which includes a bracket body having an arch wire slot formed therein; and a movable gate which slideably cooperates with the bracket body, and is moveable between a first, open position, to a second, closed position, and wherein the gate is designed so as to minimize the frictional engagement of the arch wire by the gate as the gate is moved from the first open position to the second closed position.

An orthodontic bracket comprising:
- a base member defining an archwire slot having an opening and at least one projection extending outwardly relative to the base member;
- a ligating slide moveably borne by the base member between a first position where the ligating slide is clear of the archwire slot, and a second position where the ligating slide projects over the opening of the archwire slot;
- and
- a biasing member borne by the ligating slide and slideably cooperating with the projection, and wherein the biasing member has a first portion which receives the projection when the ligating slide is in the first position, and a second portion which receives the projection when the ligating slide is in the second position.
