CLINICAL AND ECONOMIC JUSTIFICATION OF MANAGEMENT DECISIONS ON THE REPLACEMENT OF DENTAL INSTRUMENTS SUBJECT TO CORROSION

The article develops an innovative model for making a managerial decision on replacing dental instruments subject to corrosion, including a mathematical apparatus, algorithm, software in the Python software environment and a matrix of clinical and economic feasibility of restoring dental instruments subject to corrosion, and formulates a criterion for the optimality of such a managerial decision. The task of replacing dental instruments subject to corrosion has been set and solved, depending on the ratio between the total cost of restoration using the electric spark alloying method using self-healing electrodes based on
TiC-NiCr, per unit useful life and including the cost of restoration and reducing the liquid cost of the instrument, and the total cost of purchasing new instruments., consisting of the cost of the new toolkit, reducing its liquid value over the period of operation during the first period of management decision-making and the cost of disposal of corroded tools. The developed software environment and the matrix of clinical and economic feasibility show that the restoration of dental instruments, which significantly increases the period of its subsequent useful use, is economically more profitable than the purchase of new instruments subject to corrosion. The Python-based program developed by the authors makes it possible to determine the economic feasibility of restoring such an instrument in accordance with the above criteria for making a management decision compared to replacing it with new dental instruments, as well as the threshold values of the parameters for any values of restoration costs, the liquid cost of the instrument, the cost of its disposal and the increase in its useful life after restoration. influencing managerial decision-making with known values of influencing factors.
