Caracterización físico-química de la superficie de 9 implantes dentales con 3 distintos tratamientos de superficie

there are many surface treatments applied to dental implants. the aim of the present investigation is to compare the physico-chemical characteristics of titanium dental implant surfaces with different surface treatments. 9 dental implants from the same batch were divided in 3 groups and received 3 different surface treatments: machined, acid etched and a new chemical surface treatment called avantblast？. scanning electron microscopy and confocal microscopy were used to image the treated surfaces, and energy-dispersive spectrometry and x-ray photoelectron spectrometry to provide a chemical characterization of the surfaces. results: the acid etched and chemical etched surfaces had an increased roughness over the machined one. surface chemical composition had differences between processes, as the surface with the new treatment presented a reduced level of impurities and increased thickness of the titanium oxide layer conclusions: surface roughness of titanium dental implants and thickness of the titanium oxide layer can be increased with a suitable surface treatment.
