T HE aim of this paper is to discuss the treatment of malocclusions employing the adjustable bracket, and to introduce a clamp for rectangular archwire therapy, and a bracket bow-string for the rotation of teeth. These devices are original and new, projecting a simpler and more precise technique. The adjustable locking bracket was introduced in a previous paper1 and its inherent properties and advantages were described (Fig. 1). No mention was made of the adjustable edgewise bracket, which is a combination of the adjustabIe cyclinder and the Angie edgewise bracket (Fig. 2).
