FIELD: medicine. ^ SUBSTANCE: cast not non-disposable model entirely including its socle part on a working print from a supergypsum, preliminary having carried out the print preparation, consisting that a peridental zone in a print round prints of all basic teeth - a zone round a print of a dissected basic tooth, circulary fill in with wax or silicon mass for an artificial gum, after casting of not non-disposable model spend casting of non-disposable model, applying a technique of manufacturing of the combined model. Model the wax preparation of the future monoblock skeleton of a bridge-like prosthesis on non-disposable model. After the end of modelling of the skeleton, separate it on fragments depending on a clinical situation, also transfer them with non-disposable on not non-disposable model. On not non-disposable model spend bond of fragments among themselves by means of wax or plastic for interdental intersections after that on the received wax composition establish the funel-creating pegs forming a funnel system. Take out the ready funnel system together with a wax composition of the skeleton of a bridge-like prosthesis from model and place in a ditch for casting from an alloy necessary for the future bridge-like prosthesis, fill the ditch with fire-resistant packing mass, melt the wax composition in a muffle furnace and spend casting of the skeleton from the fused alloy to the obtained form. After skeleton casting first spend try-in of every basic element of the skeleton - crowns to the corresponding stamp - the tooth from non-disposable model, then carry out try-in of the whole skeleton on the non-disposable model. ^ EFFECT: rising of accuracy of manufacturing of the monoblock skeleton of fixed tooth prostheses that excludes development of undesirable complications. ^ 2 cl |
