    To characterize the surface topography of several dental implants for commercial use. Dental implants analyzed were Certain (Biomet 3i), Tissue Level (Straumann), Interna (BTI), MG-InHex (MozoGrau), SPI (Alphabio) and Hikelt (Bioner). Surface topography was ascertained using a confocal microscope with white light. Roughness parameters obtained were: Ra, Rq, Rv, Rp, Rt, Rsk and Rku. The results were analysed using single-factor ANOVA and Student-Neuman-Keuls(p<0.05) tests. Certain and Hikelt obtained the highest Ra and Rq scores, followed by Tissue Level. Interna and SPI obtained lower scores, and MG-InHex obtained the lowest score. Rv scores followed the same trend. Certain obtained the highest Rp score, followed by SPI and Hikelt, then Interna and Tissue Level. MG-InHex obtained the lowest scores. Certain obtained the highest Rt score, followed by Interna and Hikelt, then SPI and Tissue Level. The lowest scores were for MG-InHex. Rsk was negative (punctured surface) in the MG-InHex, SPI and Tissue Level systems, and positive (pointed surface) in the other systems. Rku was higher than 3 (Leptokurtic) in Tissue Level, Interna, MG-InHex and SPI, and lower than 3 (Platykurtic) in Certain and Hikelt. The type of implant determines surface topography, and there are differences in the roughness parameters of the various makes of implants for clinical use

    Caracterización topográfica de implantes de uso comercial

    El uso de implantes dentales está cada vez más extendido en la práctica diaria. Existen muchos fabricantes de implantes, ofreciendo tratamientos de superficies muy diferentes entre ellos (Sykaras N y cols.2000; Elligsen JE y cols. 2004). El tratamiento superficial es crucial para una rápida y duradera osteointegración (Botticelli D y cols.2003, Keller JC y cols. 2003, Szmukler-Moncler S y cols. 2004). En función del tratamiento que se aplica a las superficies se observa una topografía distinta con parámetros de rugosidad variables (Buser D y cols. 1998, Buser D y cols. 1991). El estudio de la topografía superficial es de gran importancia ya que la topografía condiciona la respuesta celular (Buser D y cols. 1998, Rosales-Leal J.I y cols. 2010, Wong M y cols. 2011). Optimizar la topografía permite el uso de implantes en situaciones con hueso poco favorable, elevación de seno, implantes postextracción y, como consecuencia, una supervivencia mayor a largo plazo de las rehabilitaciones orales implantosoportadas. El objetivo de este trabajo es caracterizar la superficie mediante análisis topográfico, morfológico, químico y estudio de porosidad, de 17 implantes de uso comercial.Tesis Univ. Granada.
