Ti) implants. Also, the electrolytic corrosion effects over three types of materials used on prosthetic suprastructures that were coupled with titanium implants were analysed: Noble Bond® (Argen®), Argelite 76sf +® (Argen®), and commercially pure titanium. Materials and Methods: 15 samples were studied, consisting in 1 abutment and one c.p. titanium implant each. They were divided into three groups, namely: Control group: five c.p Titanium abutments (B&W®), Test group 1: five Noble Bond® (Argen®) cast abutments and, Test group 2: five Argelite 76sf +® (Argen®) abutments. In order to observe the corrosion effects, the surface topography was imaged using a confocal microscope. Thus, three metric parameters (Sa: Arithmetical mean height of the surface. Sp: Maximum height of peaks. Sv: Maximum height of valleys.), were measured at three different areas: abutment neck, implant neck and implant body. The samples were immersed in artificial saliva for 3 months, after which the procedure was repeated. The metric parameters were compared by statistical analysis. Results: The analysis of the Sa at the level of the implant neck, abutment neck and implant body, showed no statistically significant differences on combining c.p. Ti implants with the three studied alloys. The Sp showed no statistically significant differences between the three alloys. The Sv showed no statistically significant differences between the three alloys. Conclusion: The effects of electrogalvanic corrosion on each of the materials used when they were in contact with c.p. Ti showed no statistically significant differences. 09 21 2016 486 496 TODENTJ-10-486 1 10.2174/crossmark_policy opendentistryjournal.com benthamopen.com true Peer Reviewed Single blind Checked with iThenticate 2015-12-30 2016-06-11 2016-08-7 2016-09-21 https://creativecommons.org/licenses/by/4.0/legalcode 10.2174/1874210601610010486 1553506645 https://opendentistryjournal.com/VOLUME/10/PAGE/486/ https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-486/TODENTJ-10-486.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-486/TODENTJ-10-486.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-486/TODENTJ-10-486.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-486/TODENTJ-10-486.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-486/TODENTJ-10-486.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-486/TODENTJ-10-486.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-486/TODENTJ-10-486.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-486/TODENTJ-10-486.xml Int.
