Effect of Different Titanium Surface Treatments on the Adhesion Test Result: Dental Application

Abstract

The aim of the study was to investigate the effect of different surface treatment of titanium (Ti) on the adhesion test results for dental application. Ti substrates roughened by 400 to 1 500-grit SiC polish papers and alumina blasting, alkali treated by 5 molar (M) NaOH and KOH solutions and heat treated at the temperature range of 400–800 °C were used in this study. The treated samples were subjected to the adhesion test. According to the results of the adhesion test, the adhesive strength showed the highest value for the blasted titanium among all polished and blasted samples. The Ti samples heated at 650 °C showed the highest adhesive strength among all heat-treated samples. Further, the adhesion test results indicated the higher adhesive strength of chemically treated samples treated by NaOH rather than that by KOH. The polished and heated Ti samples showed the highest adhesive strength among all samples.
