Abstract
The surface treatments are performed in dental implants in order to increase the chemical and mechanical connection between the implant and bone, favoring the stability of implant-supported prostheses. The aim of this study was to characterize dental implant surfaces treated with 37% phosphoric acid. Implant surfaces were evaluated divided into groups of fifty samples being distributed in: porcelain samples without treatment; metal samples without treatment; porcelain samples with treatment with 37% phosphoric acid for 30 seconds; metal samples treatment with phosphoric acid at 37% for 30 seconds; porcelain samples with treatment with 37% phosphoric acid for 60 seconds; metal samples with treatment with 37% phosphoric acid for 60 seconds. The samples were characterized by Scanning Electron Microscopy. After the phosphoric acid treatment porosity changes were observed and expanding the contact area. The results show benefits of using phosphoric acid, as a surface with increased roughness; this is desired to occur matrix deposition and growth of bone tissue and facilitates the fixation of implant-supported prostheses.
