Spectroscopic analysis of titanium surface functional groups under various surface modification and their behaviors in vitro and in vivo

Abstract: In the present study, surface functional groups of titanium surfaces gone through different treatments, including acid etched treatment (AE), nitric acid treatment (NT), heat treatment (HT), and alkali treatment (AT), and their behaviors in vitro and in vivo was thoroughly studied by spectroscopic analysis. In vitro and in vivo results revealed that the rank of bioactivity of various surfaces was AE < NT < HT < AT. XPS analysis indicated that AT greatly increased the OH group concentration on the titanium surf… Show more

“…Lu et al (2007) reported that Ti metal that was treated with strong nitric acid for a long period induced the formation of apatite on its surface in an SBF, although no titanium oxide was detected on its surface. Lu et al (2008) reported that acid-etched Ti metal which formed rutile on its surface by a heat treatment induced the formation of apatite on its surface in an SBF. Pattanayak et al (2009) reported that the apatite-forming ability of Ti metal with rutile and anatase on its surface after soaking in NaOH and HCl solutions, and then a heat treatment, increased with increasing concentration of the HCl solution.…”

“…XPS's surface characterization shows that following anodic oxidation, TiOx films are funconalized with À ÀPO 4 , À ÀSO 4 and À ÀOH groups. These functional groups should be (SO 4 ) 2 and H 2 (PO 4 ) 3 or HOPO 4 . 29 Compared to CT surface, chemical compositions of EAT is not clearly different.…”

“…Este mismo resultado fue reportado en otros estudios. 15,16 Fueron identificados además elementos como aluminio (Al), azufre (S), plomo (Pb), fósforo (P), calcio (Ca), sodio (Na) y nitrógeno (N), también identificados en estudios previos. 17 La presencia de contaminantes en las superficies depende en gran medida de las condiciones de fabricación, mecanizado, temperatura, exposición al aire, lubricantes, esterilización, almacenamiento, embalaje y manipulación de los implantes.…”
