FIELD: medicine. ^ SUBSTANCE: method involves forming supporting platforms on supporting teeth for fixing bridge prosthesis beams and repairing supporting teeth crown parts and crowns of teeth under substitution corresponding to their anatomical shape. The supporting platform having completely lacking crown portion is formed at the level of crown part equator by filling cavity layer-by-layer with microfilled composite material, the cavity being built by walls reinforced with gold-plated metal net and restored in advance using macrofilled composite material to the tubercles level, and by producing slit on aproximal wall surface on the same side with the defect. The supporting platform is formed on tooth having partially lacking crown portion as grooves produced at the equator level on vestibular and oral crown part surface restored in advance using macrofilled composite material and reinforced with net carcass fixed on bearing tooth stump. Supporting beam parts are shaped to conform with the shape of the supporting platforms contact surfaces and grooves shape. Gold-plated metal net is mounted on bearing parts of the beams. The net is preliminarily given M-shaped form and the beams are additionally attached to the beams and the beams are fixed to each other using thin metal threads. The grooves are as deep as the net carcass location depth. ^ EFFECT: high strength, reliability, prolonged service life; restored dental row integrity. |
