- Аннотация: We used classical screw-type dental implants from the Conmet company (Russia) and miniimplants from the 3М ESPE company (USA) fixed in osseous tissue analogs of polyurethane and linden, having different geometric parameters. Devices Periotest (Medizintechnik Gulden, Germany) and Osstell Mentor (Sweden) are used to monitor the stability of dental implants since its installation, the level of osseointegration and functional determinetion of allowable loads, especially in the initial period of their use as an artificial supports for dental and mandibular prostheses. Due to permanent technical development, the last versions of these devices (Periotest M and Osstell ISQ) have been considerably improved while there were some weak points in previous versions. We must stress that both devices give results of strength measurement for dental implants fastening in osseous tissue in some standard units which have no physical sense, therefore guidelines on the basis of only these measurements are not sufficiently proved and convincing. In this work, the last version of Periotest M was examined and parameters measured by this device were interpreted as coefficients of damping. Methods for measuring these factors through the special device for determining the mobility of the teeth or implants were proposed to achieve higher accuracy. Distribution of vertical displacement of dental implants obtained in numerical simulations by finite element method using a virtual model of a full-scale test bench is consistent with the physical experiment. A simple linear relationship between damping ratio and compliance based on the results obtained by the laser test and numerical experiment, allowing for the dental implant fixed in the bone analogue, based on readings of Periotest M to determine the value of its movement, depending on the longitudinal and transverse loads.
