The present paper is focused on the micromechanical analysis of material properties and the microscopic analysis performed to evaluate the surface morphology of enosseal part of dental compensation with cylindrical shafts as well as plasma-surface modified hydroxyapatite. Using the nanoindentation the differences in elastic modulus and hardness of the examined implants in the shaft supporting portion and the surface are compared. The mechanical tests clearly show that the differences are mainly in the peripheral layer, in the range of about 17-157 GPa. Moreover, the hydroxyapatite surface is studied by means of terms of elemental analysis and microscopy.
