AbstractAim: Purpose of our research was to match the quantity of crown inclination achieved with a pre-adjusted edgewise appliance utilizing Roth versus MBT prescription. Methodology: Forty sets of posttreatment study models from patients treated employing a preadjusted edgewise appliance (20 Roth and 20 MBT) were selected using predetermined inclusion and exclusion criteria. The models were masked and laser-scanned, and therefore the final crown inclinations were assessed from the digital images. A two-way analysis of variance was undertaken with the variable quantity of ultimate crown inclination and independent variables of bracket prescription (Roth or MBT) and tooth type. Results: There were no statistically significant differences in terms of the ultimate inclination of the anterior teeth between the 2 bracket prescriptions (P < .132). Statistically significant differences were found between the ultimate inclinations of various tooth types investigated (P< .001). Conclusion: In this group of selected patient records, the differences in torque values between the 2 bracket prescriptions failed to cause any real clinically detectable differences within the final inclination of teeth.
