Abstract
Introduction: While using preadjusted edgewise mechanics, tooth positioning relies on the accuracy of bracket prescription for correct expression of tip and torque when using full-size archwire, thus making accuracy of bracket prescription vital in its overall performance. This study aimed to investigate the precision offered in bracket prescription: slot dimensions, tip, and torque values. Materials and Methods: MBT prescriptions of upper left central incisor brackets manufactured by six different commercial houses were evaluated to assess the aforementioned accuracy of bracket slot dimensions as well as tip and torque values. Rapid-I Precision Measuring System was used to accurately determine slot dimensions as well as tip and torque values. Results: Results obtained in a descending order of accuracy were as follows: American Orthodontics, Ortho Organizers, 3M Unitek, Forestadent, Modern Orthodontics and JJ Orthodontics. The obtained results were evaluated statistically using one-way ANOVA test. P Conclusion: This study helps us to note the accuracy level of the inherent prescription values offered in various commercial houses and the likely effect the same may have on our expectation of a prescription finish while using attachments from any of them.
