Abstract

  Finishing anterior teeth with the proper torque is crucial to achieve optimal occlusion, function, esthetics, and stability. Evaluating the need for additional torque and carefully selecting brackets’ prescription should be performed on a case by case basis and before starting orthodontic treatment. This paper is presenting a novel analysis developed as a useful guide to help clinicians to conveniently assess anterior teeth torque requirement in order to select the proper brackets’ prescription before starting treatment, “Nora Torque Selection Analysis”. This analysis includes nine major components that assess pretreatment conditions and integrate individual’s treatment preference. A clinical case is analyzed and discussed for further illustration.

Keywords: Torque; Analysis; Orthodontic Bracket Prescription
