A strip-shaped straight-wire bracket, comprising a bottom plate (5) and a bracket body (1) provided on the bottom plate (5) the bracket body (1) is transversely provided with a bracket slot (2) thereon having a rectangular cross-section a preset torque degree (8) is formed between a bottom surface (201) of the bracket slot (2) and a bottom plate surface (501) a strip-shaped archwire is provided in the bracket slot (2) a wide surface of the strip-shaped archwire is fitted to a bottom surface (201) of the slot so as to generate an automatic torque. When the wide surface of the strip-shaped archwire is attached to the bottom surface of the slot by means of a conventional ligature, the teeth can generate an automatic torque to reach a normal torque degree the modification to the structure of the bracket slot and the attachment of the strip-shaped archwire to the bracket slot enable performing various tooth movements, such as alignment and leveling, retraction and torque, thus reducing the complexity of a clinical operation, increasing the efficiency and precision of tooth movement, and shortening a clinical correction period.Linvention concerne un bracket en forme de U selon la technique arc droit comprenant une plaque inférieure (5) sur laquelle repose un corps principal (1) de bracket, une section transversale de forme rectangulaire sur le corps principal (1) configurant une rainure (2) de bracket dont la surface (201) forme un angle de torsion (8) avec la surface (501) de la plaque inférieure, les fils arc droit étant logés dans la rainure (2) de bracket et le côté large des fils sadaptant à la surface inférieure (201) de la rainure de manière à obtenir une torsion automatique. Lorsque le côté large des fils sadapte à la surface inférieure de la rainure grâce à lentrelacement classique, les dents produisent une torsion automatique pour atteindre une torsion normale. La structure de la rainure se modifie et les fils sassemblent, ce qui permet un quelconque déplacement
