Abstract
Introduction. Acrylic plastics are widely used in orthopedic dentistry and orthodontics. They are the main material for the manufacture of various types of dental prostheses. To create an orthopedic product, a mixture of powder (polymer) and liquid (monomer) is obtained, from which a product of the required shape and size is formed and solidified. The resulting designs must meet the requirements for compatibility with living tissues, including the little-studied compatibility of the electromagnetic component. Main part. Dielectric materials when heated form their own electromagnetic radiation in the millimeter range, which is a general property of heated dielectrics. By this, electromagnetic flows (EMF) of different directions arise. These flows can have a positive or negative direction and in a certain way affect the adjacent biotissues and the human body as a whole. Therefore, the authors conducted studies of electromagnetic radiation (EMR) of 6 types of acrylic plastics, determined their levels and compared them with the level of EMR of biotissues of the human body. Based on the obtained results, conclusions were drawn regarding their electromagnetic compatibility (EMC). “Colorless basic plastic” and “Vertex Implacryl” have the highest level of EMC (up to 58%), “Ftorax” and “Sinma-M” plastics have a slightly lower level (48-53%) and the lowest EMC (35-36%) is recorded in “Vertex Basio” and “Ethakryl – 02”. Conclusions. Compared to the level of human electromagnetic radiation, acrylic plastics and, accordingly, dental prostheses from them form negative currents in relation to adjacent biotissues. The conducted studies allow to recommend the choice of more acceptable materials for the manufacture of dental permanent and removable prostheses, as well as to determine the correlation between the emission of electromagnetic characteristics and the appearance of complications in patients during the operation of these structures.
