Exemplary arrangements relate to methods for recording and reproducing holograms. A method of recording a hologram in a thresholded opto-magnetic medium (7) includes producing a collimated recording beam (1) with a pulsed laser. The intensity of the recording beam is selectively modulated by passage through a modulator (2). The recording beam is spatially shaped by passage through a shaping element (15). The shaped modulated recording beam is made convergent by passage through an aspheric lens (4). The convergent beam is deflected bidirectionally with a MEMS mirror (6) that is in operative connection with the modulator, such that multiple disposed locations on a surface of the medium are exposed to a constriction of the convergent shaped recording beam, causing a change in the medium in the locations. Reconstructing the hologram is carried out by illuminating the medium with a collimated laser beam and focusing with a lens, light from the illuminated medium onto a detection matrix. Additional methods of recording and reproducing holograms utilize alternative steps.

To increase dynamics of the osseointegration process, the type of material from which the implant is made, its design features, surface topography, as well as the formation of layered structures and coating applications, are described. The implant introduces growth factors and other biologically active factors that affect an increase in the dynamics of osseointegration strength.

The subject of the invention is an intraosseous dental implant for the application of biologically active agents directly to the surrounding soft tissues and bone tissue, and their substitutes, and enabling the measurement of the newly formed or lost bone tissue volume immediately adjacent to the dental implant. Increasing the dynamics of osseointegration growth directly results in the possibility of reducing the duration of the entire treatment protocol. This effect is highly anticipated by patients - the beneficiaries of therapy. In order to increase the dynamics of the osseointegration process in intraosseous dental implants, there is ongoing research on the type of material from which the implants are made, their design features, surface topography, as well as the formation of layered structures and coating applications. The use of growth factors and other biologically active factors affects the increase in the dynamics of osseointegration strength in intraosseous dental implants. The possibility of introducing these factors into the direct surroundings of the implant during healing is important. The entire implant or porous section of the implant according to the invention can advantageously be produced by 3D printing through selective melting/sintering of biocompatible metallic, ceramic or metallic-ceramic composite powders with laser or electron beam.

A method of nanocrystalline structure formation in bearing steel, characterised in that in the first stage, an element made of a commercial bearing steel with the following chemical composition (by wt. %): carbon: 0.93+1.10, silicon: 0.4÷0.75, manganese: 0.95÷1.25, chromium: 1.30+1.65, phosphorus up to 0.027, sulphur up to 0.02, nickel up to 0.3, copper up to 0.25 and unavoidable impurities, is heated to an austenitising temperature in the range of 900÷940°C and held in this temperature for 10÷45 minutes. Then, the steel is cooled to the isothermal holding temperature in the range of 300÷350°C, higher than the martensite start temperature but lower than the bainite start temperature. The cooling rate from the temperature of austenitising should be high enough to avoid the pearlite reaction, i.e. a rate higher than the critical rate preventing the occurrence of diffusive transformations. In the case of this steel, the cooling rate should be 8°C/s or higher, depending on the size of the element and the chemical composition of the steel. The subsequent annealing at the isothermal holding temperature for a period of 5-8 hours is used in order to complete the bainitic reaction, and then the material is cooled down until the room temperature is reached.

The subject matter of invention is a method for obtaining a tissue engineered product for the reconstruction and regeneration of bone tissue, the tissue engineered product, and its applications. In more detail: the invention represents the method for obtaining the tissue engineered product in cell culture conditions in vitro on degradable material. The product consists almost entirely of natural components, which are produced by cells seeded on a resorbable material. When the cells come from the donor who is also the recipient of the graft, the product is composed of his/her own biological material. Such composition ensures immunological compatibility, which does not occur in the case of biological material obtained from an incompatible donor or when the biological material is of animal origin, which is often the case in current clinical practice.
