Today, an interdisciplinary approach to solving the problems of implantology is the key to the effective use of intraosseous dental implants. The possibilities of preclinical modeling of the state of bone tissue and the future implantation and prosthetic beds allow us to assess the possible risks of implant rejection, calculate the necessary tightening force of screws in implantation systems and predict the points of application and stress distribution of dental implantation materials, taking into account the latter, the desire to improve modeling will allow us to obtain a predictable treatment result. In this study, a mathematical model of the stress distribution on the walls of a conical implant was investigated, taking into account the physical properties of the VT 6 material, an assessment was carried out using the example of computer models with embedded alloy characteristics, and the Mises distribution indicators were calculated. It is worth noting that the VT6 alloy has a very high quality, thanks to alloying additives. This titanium alloy includes aluminum, which has a beneficial effect on the strength of implants, as well as vanadium, which can increase the strength of the metal and make it more ductile. Titanium alloy VT6 has characteristics that are comparable to those of stainless steel, due to which it is considered as an inert metal for use in the oral cavity. The novelty of the proposed model lies in the fact that it operates with the minimum possible set of input data and provides adequate estimates of the most significant output parameters that are necessary for practical application. The obtained analytical results are illustrated by examples of calculating equivalent stresses in implants and peri-implant tissue for real structures of the future orthopedic prosthesis.
