| abstract: Background: It’s well known that OTM is a complex process, a plenty of factors play a role in rate of OTM, either patient related factors (age, gender, general health, tooth location etc.) or appliance related factors (bracket’s design, archwires size and material, applied force etc.) Objective: In the current study, the double slot brackets were used during leveling and alignment phase in comparison with conventional pre-adjusted brackets system in two groups of patients, to clinically assess the bonding failure, patient Preference and time taken for alignment and leveling phase. Patients and methods: The present study was conducted on twenty patients who were divided randomly into two equal groups; Experimental group (group Ι): that included 10 patients who were treated by using twin arch brackets system. While Control group (group ΙΙ) included 10 patients who were treated by using the conventional pre- adjusted edgewise brackets system. The primary outcome is evaluation of bonding failure. While secondary outcomes are patient preference and time taken for levelling and alignment. Results: An Experimental group recorded (0.5±0.71; median 0), while a control group recorded (3.8±0.92; median 4); with a statistically significant difference between groups (p=0.000). Conclusion: The twin arch bracket system decrease percentage of bonding failure but not accepted to the patients as with conventional fixed orthodontic appliance. | ||||
