Abstract |
The aim of research work is investigation of the influence of the processing type of the titanium surface on its ability to growth of bone tissue. The original methods for evaluating this ability, based on the optical density change and the degree and kinetics of sedimentation of sample components (proteins) for human immunoglobulin G (9%) were developed.Wetting capability by immunoglobulin solution according to the laying drop method as well as electron function for processed sample surface by scanning Kelvin probe method were investigated additionally. It has been established that hydrothermal processing for titanium sample surface, microarc oxidation, dispersion abrasive processing with attached ultrasound oscillations provide higher adsorption and wetting capability by solution in comparison to reference sample without processing. Though jet and abrasive processing is applied in implant production for improving osteointegration effect, it decreases protein adsorption degree. The results obtained by three above-mentioned methods correlate with each other and allow for higher degree of probability to predict expected kinetics and growth of bone tissue on titanium surface samples. |
