title: The Shear Bond Strengths of Metal and Ceramic Brackets: An in-Vitro Comparative Study.
abstract: OBJECTIVE
  This study has compared the Shear Bond Strengths (SBSs) of ceramic brackets and metal brackets.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  The shear bond strength of the ceramic brackets was found to be superior than that of the metal brackets.
