Fiber-reinforced composite (FRC) made of polymethyl methacrylate (PMMA) and E-glass fibers has been developed for bone segment defect reconstructions. It has been shown that exposed glass fibers predispose intergration of implant to bone. The aim of this study was to investigate how fibers of the implant surface can be exposed by solvent treatment and how the exposed fibers with different orientations effect the attachment of the implant to a bone simulating material
