The Laboratory of Mechanics of Biocompatible Materials was created by order of the rector of the Dagestan State Technical University of January 24, 2018 No. 11 with the support of a grant from the Government of the Russian Federation (“Megagrant”) to conduct research under the guidance of leading scientists (grant agreement dated February 5, 2018 No. 14.Z50.31.0046 ) on the topic “Biomechanics of the tissues of the oral cavity and the eyeball and optimized biocompatible materials for implantation”.

 

The head of the laboratory is Michael Vincent Swain, a renowned scientist in the field of materials science and biocompatible materials, Ph.D., professor emeritus at the University of Sydney.

 

The main direction of the laboratory for 2018-2020. - a comprehensive study of the properties of materials of human tissues, in particular tissues of the oral cavity, eyeball and organs associated with them, for the development of implants made of artificial biocompatible materials, the main properties of which are identical to the materials of living tissues.

We invite everyone interested in issues of modern biomechanics and materials science to join the procedure for protecting projects by 4-year students of DSTU on June the 9th from 9 AM to 3 PM (UTC+3). You will see how the knowledge in the field of robotics, cybersecurity of information systems, instrument engineering and applied mechanics can be effectively integrated into the medicine today to solve acute and urgent problems that operating surgeons and doctors are facing.


The academic initiator and coordinator of the project is the Honored Professor of the University of Sydney, the Head of the Laboratory of Mechanics of Biocompatible Materials at DSTU, who leads the research team on the Megagrant of the Government of the Russian Federation.


You will be able to ask your questions to both the students presenting their projects and solutions, and to invited expert practitioners:

  • Golubev Georgy Shotavich, head of the orthopedic department of MLPUZ GB №1 named. ON THE. Semashko ", the head. Department of Traumatology and Orthopedics, Physiotherapy and Sports Medicine Rostov State Medical University;

  • Epikhin Alexander Nikolaevich, Head of the Department of Ophthalmology, Rostov State Medical University;

  • Laktionov Egor Vitalievich, dentist, therapist, head of the dental department No. 2  "Dental Clinic of Rostov-on-Don";

  • Ryabichko Artyom Gennadievich, dentist-surgeon, head of the orthopedic department No. 2  "Dental Clinic of Rostov-on-Don."

The arsenal of the laboratory of mechanics of biocompatible materials of DGTU was replenished with new modern equipment - the Carl Zeiss Versa 520 X-ray non-destructive testing system (computer microtomograph). The device allows non-destructive studies of bulk microstructure, porosity, density gradient and mineralization and other parameters of hard and soft biological samples and biocompatible materials. This model provides a scan resolution of up to 0.7 microns, which makes it unique for the South of Russia and one of the best instruments in its class.

 

The importance of the device for the study of biological and biocompatible materials is difficult to overestimate. Examples of using a computer microtomograph:

 

measurement of porosity parameters of a sample of biological material,

non-destructive testing of defects and pore sizes in products made by 3D printing,

the study of the difference in density or mineralization in the volume of the sample, the identification of areas of low mineralization.

During 2019-2020 the device is planned to be equipped with an additional module for mechanical in situ testing. This will allow observing in volume a change in the structure of the sample under the influence of a mechanical load (for example, tensile or compressive).

 

The device was purchased with a grant from the Government of the Russian Federation and additional competitive funding from the Don State Technical University. The microtomograph will be actively involved in the implementation of the set for 2019-2020. research tasks. It is expected that the functions of the system will be in demand by medical research institutions of Rostov-on-Don and the South of Russia.

 


 

The direction of scientific research is the biomechanics of the tissues of the oral cavity and the eyeball and optimized biocompatible materials for implantation.

 

The research in this direction was supported by a grant from the Government of the Russian Federation (agreement dated 05.02.2018 No. 14.Z50.31.0046). The goal of the project is a comprehensive study of the properties of materials of human tissues, in particular tissues of the oral cavity, eyeball and organs associated with them for the development of implants from artificial biocompatible materials, the main properties of which are identical to the materials of living tissues.

 

Project Objectives:

  • a detailed study of the microstructure of the tissues of the oral cavity and the eyeball and tissues of neighboring organs using modern technical means: an electron microscope (SEM), a focused ion beam (FIB), x-ray methods of research, and others;
  • the study of the mechanical properties of tissues of the oral cavity and the eyeball using nanoindentation, atomic force microscopy and related mathematical models;
  • development of a methodology for assessing the microstructural characteristics and mechanical properties of graded and hierarchical structures common to a wide class of biological and biocompatible materials;
  • creation of a database on modern biocompatible materials and organization of computer selection of these materials for implants of the oral cavity, eyeball, etc .;
  • mathematical modeling of the behavior of selected implants to determine the adequacy of the resource of artificial materials when they replace human tissues;
  • development of a methodology for the production of optimized eye and dental implants from biocompatible materials, taking into account the data of experimental studies and calculation results for developed models of consolidated media.

 

The project is being implemented by scientists-mechanics, mathematicians, materials scientists, medical workers, specialists in the field of information technology and mathematical modeling.
