FIELD: medicine.SUBSTANCE: composites are mechanically activated by vibration action on a portion of the composite covering a defect. The vibration action of the portion of the composite is pursued at a vibration frequency up to 1,000 Hz generated by a device comprising at least one working portion for applying the composite on the defect rigidly attached to a handle in the form of a tubular body provided with an actuator button for actuating a battery power supply electrically connected to a micro motor generating vibrations which are transmitted through the working portion onto the composite layer by spreading over the defect surface and ensuring superficial plastic deformation at the same time.EFFECT: by means of the controlled effect of a restoration instrument on the surface of the applied composite providing maximum air extrusion from the composite, the inventions enable forming the solid one-piece composite structure and effective marginal fit of the composite to solid dental tissues, as well as reducing a probability of complications and prolonging the operational life of the composite restoration.5 cl, 2 tbl |
