Researchers from Nagasaki University Report Recent Findings in Oral Health (Surface modification with alumina blasting and H2SO4-HCl etching for bonding two resin-composite veneers to titanium)
By a News Reporter-Staff News Editor at Health & Medicine Week -- Fresh data on Oral Health are presented in a new report. According to news reporting out of Nagasaki, Japan, by NewsRx editors, research stated, "The purpose of this study was to investigate the effect of an experimental surface treatment with alumina blasting and acid etching on the bond strengths between each of two resin composites and commercially pure titanium. The titanium surface was blasted with alumina and then etched with 45wt% H2SO4 and 15wt% HCl (H2SO4-HCl)."
Our news journalists obtained a quote from the research from Nagasaki University, "A light-and heat-curing resin composite (Estenia) and a light-curing resin composite (Ceramage) were used with adjunctive metal primers. Veneered specimens were subjected to thermal cycling between 4 and 60 degrees C for 50,000 cycles, and the shear bond strengths were determined. The highest bond strengths were obtained for Blasting/H2SO4-HCl/Estenia (30.2 +/- 4.5 MPa) and Blasting/Etching/Ceramage (26.0 +/- 4.5 MPa), the values of which were not statistically different, followed by Blasting/No etching/Estenia (20.4 +/- 2.4 MPa) and Blasting/No etching/Ceramage (0.8 +/- 0.3 MPa)."
According to the news editors, the research concluded: "Scanning electron microscopy observations revealed that alumina blasting and H2SO4-HCl etching creates a number of micro-and nanoscale cavities on the titanium surface, which contribute to adhesive bonding."
