The submitted experimental analysis identifies, defines and compares the micromechanical properties of peripheral and supporting layers of intraosseous parts of dental implants through a nanoindentation method. The aim of the micromechanical tests is determination of elastic modulus and hardness. Investigated implants are characterized by the cylindrical shanks with surface plasma modification by hydroxyapatit. From the evaluated results it is evident that elastic modulus of peripheral layers of the compared samples ranges from 17 GPa to 157 GPa. The submitted work also includes a microscopic images of surface morphology and chemical composition.
