Assessment of different surface treatments and shear bond characteristics of poly-ether-ether-ketone: An SEM analysis.

Aim: The aim of this study is to assess the surface roughness and shear bond characteristics of pol-ether-ether-ketone after different surface treatments.

Setting And Design: An in vitro, prospective.

Materials And Methods: One hundred and twenty disc-shaped samples of 10 mm diameter and 2 mm thickness were milled and subjected to following surface treatments: 110 μm alumina particles, 98% concentrated sulfuric acid, and 10-20 μm synthetic diamond particles.
