Abstract:
OBJECTIVETo evaluate the effects of sandblasting and different orthodontic adhesives on shear bond strength between zirconia and enamel.
METHODSZirconia ceramic samples were designed and manufactured for 40 extracted human maxillary first premolars with CAD/CAM system. The samples were randomized into 4 groups for surface treatment with sandblasting and non-treated with adhesives of 3M Transbond XT or Jingjin dental enamel bonding resin. After 24 h of bonded fixation, the shear bond strengths were measured by universal mechanical testing machine and analyzed with factorial variance analysis.
RESULTSThe shear bond strength was significantly higher in sandblasting group than in untreated group (P<0.05) and comparable between the two groups with the adhesives of Transbond XT and dental enamel bonding resin (P>0.05).
CONCLUSIONThe shear bond strength between zirconia and enamel is sufficient after sandblasting regardless of the application of either adhesive.
