METHOD OF DETERMINING STRENGTH OF COMMUNICATION OF DENTAL RESTORATION MATERIAL WITH TOOTH DENTAL SPECIMEN AND DEVICE FOR IMPLEMENTATION THEREOF Russian patent published in 2020 - IPC A61C7/12 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment. Method consists in testing a sample of "hard dental tissues-dental restorative material" in conditions imitating the oral cavity through a thermal cycling process, adding an enzyme alpha-amylase and applying vibration forces, wherein connection of dental restoration material with hard tooth tissues is considered satisfactory, if they did not disconnect during 8760 hours. Implementation of the method is carried out using a device consisting of a metal platform with two recesses, filled with physiological solution of different temperature, vertical stepper motor with a reduction gear and a microcontroller, to which a bar for fixing a sample of "hard dental tissues - dental restorative material" is fixed, a horizontal step motor with a reduction gear and a microcontroller for moving the platform in a horizontal direction, a power supply, a vibration motor unit for generating a vibration load of the low-frequency oscillation and transmitting it to the platform.

EFFECT: technical result is reduced to providing measurement conditions to conditions close to conditions in oral cavity.
