Introduction: Bonding failure is recognized as the main concern in the daily practice of orthodontics. The failed bracket are usually rebonded on the tooth surface and several techniques have been used such as sand-pining and re-etching to enhance the effectiveness of bracket bonding to teeth surface. However, there are few investigations examined. The bond strength of bracket and the effectiveness of enhancement techniques have never been studied. Materials and methods: In this investigation, the shear bond strength of two different rebonding techniques of sandblasting and re-etching which are common in dentistry were evaluated and compared with primary bonding strength. Results: The mean shear stress for primary bonding interface (control samples) of brackets was 172.11 kg force/cm 2. These values for rebonded brackets using two techniques of sandblasting and re-etching were 165.89 kg force/cm 2 and 144.23 kg force/cm 2 , respectively. Conclusion: However, there was no significant difference in the shear strength responses of three groups. The results of the study showed that both techniques of rebonding of failed brackets can provide effective bonding strengths similar to the primary strength.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
