FIELD: medicine.
SUBSTANCE: method involves preparing teeth for making crown, taking imprint, producing collapsible model, forming fibrous carcass and subjecting it to polymerization. Teeth preparation is carried out with 0.8-1.3 mm wide supragingival circular shelf and with 1.5-2.0 mm wide on occlusion surface. The collapsible model is covered with rubber-like lacquer and dried at room temperature. Thin creamer layer is applied on dental stumps. Prosthesis carcass formed preliminarily measuring required fibrous ribbon length, impregnating it with liquid composite, cutting 6 or 8 equal strips and superimposing them one over the other to produce multi-layer ribbon, stretching it all its length along and determining its middle. Then, the finished ribbon is fixed on stump 1 as throw-on loop. Ribbon ends are connected and twisted in spiral with maximum tension on connection beam side to the next stump 2, that is wrapped with ribbon ends remaining free and fixed on stump 2 prepared for setting crown with end overlap of 2-3 mm or fixed on stump 2 prepared as inlay. Then, The carcass is layer-by-layer covered with creamer: pericervical layer, dentine and enamel. After having been polymerized, the ready prosthesis is polished.
EFFECT: producing large dental bridges without using metal; improved functional properties.
