The Effect of Adhesive Type and Thickness on Bond Strength of Orthodontic Brackets

Abstract

Fine-mesh hased hrack ets were handed to plastic cylinders using four different adhesives. Adhesive thickness was controlled using a bonding jig. The bond was then tested to failure using a shear force. Each adhesive had its own minimum thickness, probably related to its viscosity. Increasing the thickness of the adhesives to 0·26 mm, using a stainless steel spacer had minimal effect on their mean shear bond strength.
