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

Abstract

Existen diversos tratamientos de superficie aplicados a los implantes dentales. El objetivo del presente estudio es comparar las características físico-químicas de la superficie de implantes dentales de titanio sometidos a diversos tratamientos de superficie. 9 implantes dentales procedentes del mismo lote de fabricación fueron separados en 3 grupos y sometidos a 3 tipos de tratamiento de superficie diferentes: mecanizado, grabado ácido y un ataque químico denominado Avantblast®. Las superficies obtenidas fueron observadas mediante microscopía electrónica de barrido y microscopía confocal, y caracterizadas químicamente mediante energía dispersiva de rayos X y espectrometría de fotoelectrones. Resultados Las superficies grabadas al ácido y las tratadas con ataque químico fueron más rugosas que las mecanizadas. La composición química superficial fue diferente entre procesos, en la superficie con el tratamiento de ataque químico existieron menos impurezas y un mayor espesor de la capa de óxido de titanio. Conclusiones La rugosidad superficial de los implantes dentales de titanio y el espesor de la capa de óxido de titanio se pueden incrementar mediante un adecuado tratamiento superficial de ataque químico.

There are many surface treatments applied to dental implants. The aim of the present investigation is to compare the physicochemical 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.
