Correction of horizontal and vertical discrepancies with a new interactive self-ligating bracket system: the Quick system.

Abstract

In the past 10 years, self-ligating brackets have captured the interest of many clinicians and enjoyed increasing popularity. These brackets have been developed to overcome the disadvantages of stainless steel or elastomeric ligatures in terms of ergonomics, efficiency, deformation, discoloration, plaque accumulation, and friction. A self-ligating bracket does not require any type of ligature because it is has a mechanical device that opens and closes the edgewise slot. Secure archwire engagement may be accomplished by a built-in clip. Depending on the interaction between the bracket and archwire, self-ligating brackets can be active and passive. The aim of this article is to describe a new active self-ligating bracket system designed to noticeably reduce the amount of friction that normally originates from archwire-slot interaction, particularly during the correction of horizontal and vertical discrepancies.
