Abstract: The invention relates to the field of dentistry. The present invention according to the first aspect provides a lightweight, durable monolithic bend-resistant dental prosthesis intended to eliminate of tooth defects, such as missing coronal portion at the gumline, 2 mm above the gumline and below the gumline which comprises a double coronal-root reinforcing, supporting part and a dental restorative material part. The dental restorative material part encapsulates the coronal part of the double coronal-root reinforcing, supporting part. The double coronal-root reinforcing, supporting part comprises at least one expanding frame and a mesh coronal-root frame positioned in the root and coronal parts of the double coronal-root reinforcing, supporting part.

Abstract: The invention relates to medicine, namely to dentistry and is intended to reinforce composite materials used for elimination various defects of hard dental tissues of carious and non-carious origin in the process of direct/indirect, reinforced/unreinforced composite restoration. The claimed method includes vibrational mechanical activation of composite materials by a vibrational impact on portions of composite material shaped by manual mechanical activation (e.g., roll/ball) and applied layer by layer to a defect area. A device for vibrational mechanical activation of a composite material includes at least one working part for applying a composite material to a defect, the working part fixedly attached to a handle, which is connected by a framework to a micromotor that creates vibration which are transferred via the working portion to a layer of composite material by distributing the same across the entire surface of the defect and achieving the simultaneous surface plastic deformation thereof.

Abstract: The invention relates to the field of dentistry and is intended for restoration/reconstruction of teeth decayed/fractured below the gum line using reinforcement technology of composite materials. The indirect atraumatic method for restoration/reconstruction of teeth decayed/fractured below the gum line comprises using a metal mesh-reinforced composite (MMC) dental prosthesis according to M. L. Melikyan, which is made by a laboratory method using gypsum models. The metal mesh-reinforced composite (MMC) dental prosthesis is comprised of a flexible crown-root wire pin and reinforcing crown-root frame assembly made from a mesh and free mesh wires. The walls of the crown part of the dental prosthesis are formed from a composite material.

Abstract: The invention relates to the field of dentistry and is used for reinforcing composite materials to eliminate various defects of dental hard tissues of carious and non-carious origin in the process of direct/indirect and reinforced/non-reinforced composite restorations. The claimed method includes vibrational mechanical activation of composite materials by vibrationally acting upon portions of composite material shaped by manual mechanical activation (e.g., roll/ball) and applied layer-by-layer to the region of a defect.
