Abstract
Objective:To determine the bond failure pattern and time to first bond failure at an orthodontic clinic. Materials and
Methods:
The study included 63 subjects meeting the study criteria. A total of 1074 brackets (Roth prescription 0.022 slot) were bonded to incisors, canines, and premolars using a no-mix adhesive (Unite, 3M Unitek). The survival and failure rates of the brackets were evaluated by tooth position in the dental arch, sagittal occlusal relationship, and gender of the Patients. Overall bracket survival rates were estimated using the Kaplan-Meier test.
Results:
The total percentage of bond failure was 17.87%. The mean survival time for the sample was 235 days (SE = 32.27 days). Significantly higher failure rates were observed for posterior than anterior teeth (P Conclusion: For 1074 brackets bonded with a no-mix adhesive system in 63 Patients, the mean time until first bracket failure was 235 days. The overall failure rate of brackets was 17.87%.
