FIELD: medicine.
SUBSTANCE: method involves applying endodontic treatment of root, forming cylindrical cavity in root canal and shock-absorbing cavity on its base, forming reinforcement pin and ring-shaped crown carcass from gold-coated metal gauze. Root pin part is fixed in root canal after having restored artificial enamel layer from macrofilled composite material in correspondence with single-root premolar anatomical structure and fixing reinforcing carcass on internal surface formed by enamel layer. The tubular root part has longitudinal slit and free gauze wires at the end. The pin part above the root made as free gauze wires in the root part is fixed on the shock-absorbing root cavity surface. The root portion of the pin is formed in conformance with canal cavity shape. Root part length and length of part above the root is selected no to be less than 1/3 of root canal length and not less than less than double-length of the shock-absorbing root base cavity. Crown cavity is layer-by-layer filled with macrofilled composite material. Chewing surface tubercles is restored from macrofilled composite material corresponding to anatomical tooth shape.
EFFECT: retained tooth root as base for making prosthesis ; high strength and stability of the pin and repaired tooth; simplified pin design.
