Abstract
Excessive force during crimping can cause gabling of the wire. 30 samples each with 0.019'' x 0.025'' stainless steel wire were surface treated: sandblasted only; metal primed only; and both sandblasted and metal primed. Flowable composite posts were prepared on it. A universal mechanical testing machine was used to measure debond force. The mean shear bond strength for flowable composite posts on 0.019″ x 0.025″ stainless steel wires in this study was 16.29 MPa. It was 11.33 MPa with sandblasted wires and 8.51 MPa with metal primed wires. Sandblasting or metal priming increases the bond strength of flowable composites to stainless steel wires.
