Abstract

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.

Keywords: Bracket; Ceramic; Metal; Shear bond.
