FIELD: medicine.
SUBSTANCE: method involves applying endodontic treatment to root canals, forming cavities in each of canals with depth not exceeding 1/2 - 1/3 times length of the corresponding canal after having prepared demineralized tissues of cervical root one-third with preparation surface relief being preserved and forming destroyed root walls from macrofilled composite to gingiva level with following immobilization of roots separated due to perforation by means of at least one preliminary generated reinforcing immobilization wire pin fixed by means of glass ionomer cement in root canal cavities to be joined, on a root base surface and on naked interradicular septum surface not more than by 1/3 of its height. Intracanal parts are formed as interlaced gilt metal wires and bent relative to intermediate supracanal pin parts according to fixing canals direction. The intermediate supracanal part manufactured from same not interlaced wires repeats root base surface relief and naked interradicular septum surface relief. At least one coronal part cavity walls pin is formed after fixation from macrofilled composite to occlusion surface level with formed coronal cavity being subsequently reinforced to equator level by means of coronal carcass produced from gilt metal mesh fixed by means of glass ionomer cement in coronal cavity and by means of three additional pins on the root base. The bifurcation or trifurcation zone and interradicular septum is closed with glass ionomer cement. The intraradicular parts of additional pins are placed in canal cavities through perforated openings in coronal carcass by means of glass ionomer cement together with preliminary fixed intracanal parts of immobilization wire pin. Fixed coronal carcass cavity is filled with microfilled composite, and then damping a cavity on equator level and coronal part walls from equator to occlusion surface are reinforced by means of the second coronal net carcass fixed with glass ionomer cement. The second coronal net carcass cavity is filled to occlusion surface level with microfilled composite composite. Tubercles are restored from macrofilled composite.
EFFECT: enabled stability and strength of perforated root; simplified lateral teeth repair; reduced risk of traumatic complications.
