Özet

Background The chemical surface structure of the porous titanium grafts has not been found to study in the literature on the similarity of chemical surfaces of different commercial dental implants. Purpose The purpose of this study is to investigate the chemical composition and surface energies of white (WPTG) and black porous titanium granules (PTG) by energy dispersive x-ray spectrometry (EDX) analysis to compare with different commercial dental implant surface. Materials and Methods The surface chemical compositions of six commercially available dental implants with different surface structures, PTG and WPTG were examined by EDX analysis. Surface analyzes were performed on the apical, middle, and coronal parts of each implant and on the top, flank, and valley regions on each side. Surface analyzes of dental implants were evaluated at x200 and x2000 magnifications. The EDX evaluation of PTG grafts were evaluated at x250, x2000, x5000, and x50 000 magnifications. Results PTG grafts showed elements of Na (8.88 +/- 9.98%), Cl (2.44 +/- 1.96%), and Al (0.99 +/- 0.37%) as well as Ti (90.06 +/- 11.34%) molecule at x5000 magnification. In WPTG, Ti (%34.55 +/- 6.41%) and O (%65.44 +/- 6.42%) molecules were detected. Conclusions It has been found that PTG surface was not made of pure titanium, it has different chemical molecules at larger magnifications. Cell culture and experimental studies are needed to establish a relationship between the different commercial implants and the surface structure of the titanium granules.
