Background: The aim of the study was to determine the percentage of bond failures of placed brackets with a modified direct method in patients of both genders, different ages and malocclusion types during 12 months of initial bonding. Material and Methods: The retrospective clinical study covered the period from November 2019 to December 2022 and included thirty patients with an average age of 17.07±5.35 8 males,( average age 18.77±7.87), and 22 females, (average age 16.45±4.17) who met the criteria. A total of 600 brackets with a 0.022" slot size (Mini Sprint ®, Forestadent, Germany) were placed by a modified direct method using thin paste adhesive (Reliance Light Bond™, Itasca, USA) by one operator. The observation of bond failures lasted 12 months. Results: The total number of bond failures was 10 (1.67%), where eight patients (26,7%) experienced unwanted debonding. The number of failed brackets in relation to age and malocclusion did not show statistical significance. There was a clinical difference between the genders, in 18.2% of women and in 50% of men. Statistical significance in number of failed brackets was not significant (HR=0.343; 95% CI: 0.084-1.394; p=0.135). Conclusion: The modified direct bonding method did not show differences at the level of age, gender and type of malocclusion, but it can be one of the methods of choice during direct bonding.
