Introduction: The Damon passive self-ligating system introduced broad archwires and a passive clip with posterior expansion and with minimal tipping of the teeth. Aim: To evaluate and compare the effectiveness of Damon brackets and Damon arch wires in maxillary arch dimensional changes with that of conventional brackets and conventional archwires. Materials and Methods: A total of 20 patients were selected for the study and randomly divided into 4 Groups with 5 patients in each group. Records (Study models) were taken before starting the treatment (T0) and at the end of leveling and alignment (T1) for all the 20 subjects. Pre-treatment (T0) and at the end of leveling and alignment (T1) study models were assessed for inter canine width, inter first premolar width and inter first molar width. Results: There was statistically significant increase in maxillary arch width in Damon system and conventional bracket with Damon archwires when compared to conventional bracket system and Damon brackets with conventional archwires. Conclusion: The use of conventional or self-ligating brackets does not seem to be an important predictor of change in maxillary arch width in non-extraction patients. The amount of increase in arch width was due to Damon archwires and not because of Damon brackets. Keywords : Damon brackets, Self-Ligating brackets, Arch Expansion, Archwires
