Description
Formy do wyrobu sztucznych zebów o- trzymuje sie, wykonywajac odbitke (nega¬ tyw) odpowiedniej czesci jamy ustnej w ma¬ sie specjalnej, poczem wnetrze tej odbitki, po powleczeniu stosowna ciecza, wypelnia sie gipsem. Negatyw zostaje odlaczony na¬ stepnie mechanicznie, dzieki czemu otrzy¬ muje sie pozytyw zeba. Mechaniczne odla¬ czanie powoduje jednak bardzo czesto u- szkodzenie pozytywu. Masa wedlug niniej¬ szego wynalazku umozliwia otrzymywanie pozytywu, którego mechaniczne odlaczanie od negatywu jest zbedne.Masa wedlug wynalazku sklada sie z mieszaniny przesianego gipsu alabastrowe¬ go i maczki ziemniaczanej w stosunku 5 : 1 z dodatkiem 1% drobnoziarnistej soli ku¬ chennej lub alunu i %% mieszaniny mento¬ lu i czerwonego bolusu. Ta ostatnia mie¬ szanina sluzy do zabarwiania produktu i nadawania mu odpowiedniego smaku. 0- trzymana masa, rozpuszczona w wodzie, twardnieje w ciagu krótkiego czasu, a po u- mieszczeniu jej w zimnej wodzie i ogrza¬ niu do 80 — 90°C rozpuszcza sie ponow¬ nie.Powierzchnia wewnetrzna negatywu, o- trzymanego z takiej masy, zostaje, po osu¬ szeniu w ciagu 15 — 30 minut, powleczona równomiernie roztworem szkla wodnego i wody w stosunku 1 : 2 zapomoca pendzla, poczem roztwór ten zostaje roztarty rów¬ niez zapomoca pendzla. Negatyw, osuszony nastepnie ponownie w ciagu 15 minut, zo-staje zanurzony na przeciag 1 — 2 minut w zimnej wodzie i wypelniony gipsem alaba¬ strowym.Po stwardnieniu tego gipsu (pozytywu), negatyw z pozytywem zostaje umieszczony w naczyniu, napelnionem zimna woda, któ¬ ra ogrzewa sie do 80 — 90°C, przyczem masa negatywu rozpuszcza sie, dzieki cze¬ mu otrzymuje sie pozytyw nieuszkodzony. PLForms for the production of artificial teeth are held by making a print (negatives) of the appropriate part of the mouth in a special mass, and then the interior of this print, after coating with a suitable liquid, is filled with plaster. The negative is gradually disconnected mechanically, so that a positive tooth is obtained. However, mechanical de-stressing very often damages the positive. The mass according to the present invention makes it possible to obtain a positive, the mechanical separation of which from the negative is unnecessary. The mass according to the invention consists of a mixture of sieved alabaster gypsum and potato flour in a ratio of 5: 1 with the addition of 1% fine grain salt or alum and %% of a mixture of menthol and red bolus. The latter mixture serves to color the product and give it the desired flavor. The mass, dissolved in water, hardens within a short time, and after being placed in cold water and heated to 80-90 ° C, it dissolves again. The inner surface of a negative made of such mass is, after drying for 15-30 minutes, uniformly coated with a solution of water glass and water in the ratio of 1: 2 with a brush, and the solution is then rubbed without using a brush. The negative, then dried again within 15 minutes, is immersed for 1 - 2 minutes in cold water and filled with alabaster plaster. After this plaster (positive) has hardened, the negative with positive is placed in the vessel, filled with cold water, which heats up to 80-90 ° C, when the mass of the negative dissolves, thanks to which the positive is obtained undamaged.
