Implants were placed in the femurs of miniature pigs. After 3 and 6 weeks respectively, the implants were removed and analyzed. Signifi cant differences were noted in the percentage of B.I.C. (Bone Implant Contact). Polished, sandblasted with fi ne grit, or acid etched implant surfaces had the lowest percentage of B.I.C. (B.I.C. < 25%). Grit-blasted (coarse grit) or T.P.S. (Titanium Plasma Spra...

Introduction: Various surface treatments have been used to improve the adhesion of resin cement to zirconia restorations. The present study aimed to investigate the effects of different surface treatments on the bond strength of resin cement to zirconia (Y-TZP) in clinical practice. Methods: thirty square Y-TZP samples were classified into three groups of 10, including group SB (50 µm sandblast...

toluene and benzene were eliminated using multi-walled carbon nanotubes (mwcnts). in order to investigate influence of acid treatment on the mwcnts adsorption capacities, the mwcnts were functionalized by nitric acid (10 m) under reflux conditions for 2 h. fourier transform infrared (ftir) and raman spectroscopy were employed to confirm the formation of functional groups on the nanotubes surfac...
