Method for making dental impressions

摘要: A material and method are disclosed facilitating the forming of impressions teeth and/or supporting structures, such as alveolar ridge to be duplicated restored. An elastomeric impression material, preferably subject photochemical or chemical curing, is provided, for example formed from polyesters, polyethers, polysulfides, silicones, ethylene imines, derivatives thereof, containing a filler talc, calcium carbonate, colloidal silica, glass, quartz, acrylates, etc., impregnated with hemostatic agent vasoconstrictor astringent like serving maintain subgingival tissue in retracted condition without bleeding, so permit an taken tooth surface area volume extending below gumline, requiring use gum retracting cords bands. In use, portion cord, ring rhomboid shape, like, wedged between conform contour cured by means. This procedure followed taking adhering gum, thereby providing exact duplication tooth, both above gum. The materials may color-coded delineate soft hard tissue. By making photochemically chemically curable time controlled, dentist reline dentures need laboratory work, it other ways not limiting those mentioned.
