Abstract

Four types of three-dimensional plasma capillary-porous titanium coatings for model intraosseous implants are developed. By means of pulsed microplasma oxidation in solutions or plasma spraying of powders, additional bioactive coatings on the basis of calcium phosphates are deposited on the Ti coating surface. Shear strength values of the interface between the implants coated and osseous block after 16 weeks of implantation are 4.25–4.81 MPa, while for implants with additional plasma hydroxyapatite coating it exceeds 6.19 MPa after 4 weeks of implantation.
