Comparison of Micromechanical Parameters of Different Dental Implants Using Nanoindentation
Original language description
The aim of this work is the description of microstructure and comparison of micromechanical properties of cylindrical shaped intraosseous parts of dental implants with plasma modified surface and with threaded modification. Differences in elastic parameters (such as reduced modulus (Er) and hardness (H)) of investigated implants within the supporting part of the shaft and surface layer in two different directions (longitudinal and lateral) are compared using experimental method of nanoindentation. Machined implants of titanium alloys Ti6Al4V with plasma modified surface of sprayed titanium with hydroxyapatit (HA) Ca10(PO4)6(OH)2 from different batches of product were available for measurements. EDS elemental analysis revealed a heterogeneous structure and various concentrations of the essential chemical elements (C, O, P, Ca) on the surface of implants. Differences of Er in case of peripheral hydroxyapatite layer were in range of ~145 GPa – ~163 GPa according to the exact composition of surface modification in the individual batches of the product. The difference of Er in a longitudinal/lateral direction is approximately 10%.
