Zusammenfassung

Titanium is a biomaterial largely used on dental implant manufacturing. However, as a consequence of its intrinsically low bioactivity, the development of distinct superficial treatments in order to enhance its osseointegration properties is being studied. In this sense, the use of titanium implants with a higher level of roughness has been broadened, recurring to the application of sand-blasted acid-etched surface treatments. In this article, a study of two distinct titanium surface treatments has been carried out, regarding the physico-chemical properties (roughness, hydrophilicity and chemical composition) of each, as well as the pattern of adhered proteins onto each surface (proteomic study). Hence, mass spectrometry analysis allowed the detection of 218 distinct adsorbed proteins, being 37 of those related to bone regenerative processes and dental implant integration. Moreover, using differential quantification between associated proteins, comparing surfaces, it was observable a greater affinity of APOE, ANT3 and PROC proteins to the treated surface, directly linked to the bone regenerative process. On the other hand, the treated surface displays lower affinity of CO3 protein. The variations between the adsorbed protein profiles could be an explanation for distinct in vivo outcomes.
