Comparative evaluation of torque prescription of commercially available 018Roth and 022MBT PEA brands in maxillary anterior teeth.

Background: Torque is an important component of preadjusted edgewise prescriptions to achieve ideal/optimum tooth position and more so in aesthetics sensitive maxillary anterior teeth.

Methods: The method involved perfect superimposition of two standardized images: one delineating facial axis of the tooth with stainless steel straight wire and other with full dimension arch wire engagement in bracket.
