FIELD: medicine.
SUBSTANCE: method involves applying endodontic root canal therapy, treating cavities in each canal being not deeper than 1/2-1/3 times corresponding canal length after preparing demineralized tissues of cervical one-third of the root and interradicular septum with flat surface being formed, forming walls from macro-filled composite material at the level of equator with arisen crown part being formed next using gauze crown carcass fixed in the crown cavity with glass ionomer cement and additionally attached to the root by means of at least one immobilizing pin and three additional pins prefabricated from gold-plated metal wires. The pins are mounted in canal cavities through crown carcass perforation holes and on internal surface of crown carcass bottom part. Intraradicular parts of the immobilizing wire pin manufactured as wire braids are fixed in canal cavities of roots to be united. Crown part walls are reconstructed from equator to occlusion surface using macro-filled composite material with damping cavity built at equator level. The crown part formed by restored walls and damping cavity surface is reinforced with the second prefabricated crown carcass fixed by means of glass ionomer cement and its cavity being filled with macro-filled composite material to the occlusion surface level. Tubercles are rebuilt using macro-filled composite material.
EFFECT: high strength and vertical displacement stability.
