Incidence of Orthodontic Brackets Detachment During Orthodontic Treatment

Abstract

Introduction: For orthodontic treatment with fixed appliances, it is important that the brackets and tubes be accurately positioned and that the bonding failure rate during treatment be minimised. The bracket bonding procedure plays a major role in achieving an optimal outcome during orthodontic corrective procedures, as the required tooth movement relies upon it. Bracket detachment during corrective procedures may also lead to increased treatment duration, damage to tooth enamel, and increased chair-side time due to re-bonding procedure. Consequently, it could also raise the costs of the overall treatment.
Aim: To evaluate the incidence of Orthodontic brackets detachment during Orthodontic treatment.
Materials And Method: Using electronic database 60 patients were evaluated and 1440 MBT metal brackets were included. Duration of the study took place for 6 months at Saveetha dental college and hospitals, Chennai. Bond failure of incisor,canine, premolar and molar tubes were recorded.
Results: The mean age of patients in this study was 18.5. Highest bond failure is observed with molar tubes with a bonding failure in molar of 19.5% followed by premolar brackets with a bonding failure of 7.9%.
Conclusion: From this study it is concluded that highest bonding failure is seen in the posteriors rather than the anteriors. Molar tubes have a higher bonding failure compared to premolar brackets.
