چکیده

AIM This study has compared the Shear Bond Strengths (SBSs) of ceramic brackets and metal brackets. MATERIALS AND METHOD Forty freshly extracted, human maxillary first premolars were selected for bonding. They were equally bonded with ceramic brackets (Transcend series 6000) and metal brackets (Mini Dynalock Straight wire brackets). A no - mix orthodontic adhesive system was used. Their shear bond strengths were measured by using the Instron universal machine. RESULTS The mean bond strength of the ceramic brackets was 20.68 ± 3.89 Mpa and that of the metal brackets was 12.15 ± 1.32 MPa. CONCLUSION The shear bond strength of the ceramic brackets was found to be superior than that of the metal brackets.

Comparison of shear bond strength of the stainless steel metallic brackets bonded by three bonding systems

Introduction: In orthodontic treatment, it is essential to establish a satisfactory bond between enamel and bracket. After the self-etch primers (SEPs) were introduced for the facilitation of bracket bonding in comparison to the conventional etch-and-bond system, multiple studies have been carried out on their shear bond strengths which have yielded different results. This study was aimed at co...
