Micro X-ray Spectral Analysis and Comprehensive In Vivo Study of Modified Titanium Implants.

We developed a technique for the complex modification of the surface of dental implant made of VT1-0 titanium that included sequential mechanical treatment and irradiation with powerful ion beams. The chemical composition and physical properties of the surface of titanium implants (VT1-0 grade) sandblasted with subsequent acid etching, as well as subjected to complex treatment (sandblasting and irradiation with powerful ion beams) were evaluated using micro-X-ray spectral analysis. In in vivo experiments, osseointegrative properties of the implants subjected by these treatments were compared.

Application of Barophoresis in Chronic Generalized Periodontitis: a Mathematical Substantiation.

Unlabelled: was to evaluate the use of barophoresis for the delivery of liquid-air drug substances to the gums using a mathematical model of the interaction of the drug mixture with periodontal tissues.

Materials And Methods: The solution to the problem was preceded by generation of a geometric CAD model of the device and nozzle for barophoresis, including the nozzle and injector geometry. The Ansys SpaceClaim software package was used to generate the CAD geometry.

Interaction of Various Variants of the Nanostructured Surface of Titanium with MSCs Isolated from Adipose Tissue.

Titanium has been successfully used in dental implantology for a long time. Due to the osseointegration process, titanium implants are able to withstand the chewing load. This article is devoted to the study of surface treatment methods of titanium alloys and the study of their interaction with mesenchymal stem cells (MSCs).

Biocompatibility and Bioresorption of 3D-Printed Polylactide and Polyglycolide Tissue Membranes.

We studied biocompatibility and bioresorption of 3D-printed polylactide and polyglycolide tissue membranes. Ultrasound microscopy and histological examination showed that membranes fabricated of a copolymer of lactic and glycolic acids in a mass ratio of 1:9 are bioresorbed and have good biocompatibility with soft tissues (connective tissue, adipose tissue, and epithelium). An important feature of the copolymer membranes, which differs them from pure polylactide membranes, is the formation of a thin fibrous capsule that did not interfere its destruction by the mechanism of hydrolytic resorption.

Note: Performance of a novel electrostatic quadrupole doublet for nuclear microprobe application.

The newly designed and constructed electrostatic quadrupole doublet (EQD) at the University of North Texas (UNT) has achieved mass independent focusing of MeV particles to a spot size of 3.3 × 3.5 m.
