Ion Release from Dental Implants, Prosthetic Abutments and Crowns under Physiological and Acidic Conditions

Ion release from dental implants and prosthetic restoration can affect osteointegration implant viability over a long period of time. Therefore, the aim this study was to ion crowns, with without intermediate anodized abutments, in two different media, simulating clinical conditions. The implants, abutments Cr–Co crowns were divided into groups depending on media: Hanks’ solution 1% lactic acid, body fluids microbiologically conditioned fluids, respectively. followed ISO 10271:2011 10993-15:2000 standards modified simulate replacement oral environment. ions’ measured by inductively coupled plasma mass spectroscopy (ICP-EOS), only aluminum, chromium, cobalt, titanium vanadium identified. concentration higher acid than at all time points (p < 0.05). Only showed very low no statistically significant differences = 0.524). Both immersion medium influenced ions affected corrosion these structures. presence an abutment also release, as level lower component.
