Description
Vynález sa týká prostriedku na odlahčovanie detailných modelov v zubnej technike.BACKGROUND OF THE INVENTION The present invention relates to a composition for detaching detailed models in dental technology.
Detailně modely v zubnej technike sa od1'ahčujú lakom na nechty, alebo nitrocelulózovým lakom. Nevýhoda tohoto postupu je, že uvedený lak po nanesení na detailný model tvrdne veími pomaly až niekofko hodin.In detail, models in dental technology are attracted by nail varnish or nitrocellulose lacquer. The disadvantage of this procedure is that after application to a detailed model, the lacquer hardens very slowly up to several hours.
Uvedené nevýhody odstraňuje riešenie podlá vynálezu, ktorý spočívá v tom, že ako odlahčovací prostriedok sa použije roztok acetylcelulózy o koncentrácii 0,5 až 3 g. 1_1 a stupni acetylácie 0,6 až 3 v dichlórmetáne, octane etylnatom, acetone, alebo v zmesi uvedených rozpúšťadiel, obsahujúci 0,05 až 0,2 g . I"1 1,2,3,4,5,6-hexa-O-acetyl-D-glukopyranózy, alebo 1,2,3,4,6-penta-O-acetyl-D-glukopyranózy, alebo 2,3,4-tri-O-acetyl-l,6-anhydro-beta-D-glukopyranózy a 0,05 až 0,5 g . . I*1 bronzového prášku o velkosti zrna 0,04 až 0,05 mm. Výhodou uvedeného odlahčovacieho prostriedku je, že nanesená vrstva velmi rýchlo, už v priebehu niekolkých minút, tvrdne, pričom vytvořený film acetylcelulózy je dostatočne tvrdý a pri modelácii sa nepoškodzuje. Vytvořený film acetylcelulózy s použitím horeuvedených acetylovaných derivátov glukózy, ako zmakčovadiel, je dostatočne pružný a nelúpe sa ani po dlhšej expozícii na vzduchu. Přednosti nového výrobku a jeho přípravy sú zřejmé z príkladov, ktoré sú vyčerpávajúce ale ilustrativně. Příklad 1The above-mentioned drawbacks are solved by the solution according to the invention, which comprises using a solution of acetylcellulose having a concentration of 0.5 to 3 g / l and a degree of acetylation of 0.6 to 3 in dichloromethane, ethyl acetate, acetone or a mixture of the above mentioned. of solvents containing 0.05 to 0.2 g. 1,2,3,4,5,6-hexa-O-acetyl-D-glucopyranose, or 1,2,3,4,6-penta-O-acetyl-D-glucopyranose, or 2,3 Of 4-tri-O-acetyl-1,6-anhydro-beta-D-glucopyranose and 0.05 to 0.5 g of a bronze powder having a grain size of 0.04 to 0.05 mm. For example, the deposition means that the deposited layer hardens very quickly, within a few minutes, while the acetylcellulose film formed is hard enough and does not get damaged in the modeling process. The advantages of the new product and its preparation are evident from the examples which are exhaustive but illustrative.
Acetylcelulóza — 0,5 g — o stupni substitúcie acetylovými skupinami 3 sa rozpustí za stálého miešania v dichlórmetáne — 100 milililtrov — pri teplote 20 °C a přidá sa 0,05 grantov 1,2,3,4,6-penta-O-acetyl-D-glukopyranózy a 0,5 g měděného prášku o velkosti zrna 0,0.5 mm. Uvedenú zmes dobré premiešame pretrepaním a natierame štetcom na povrch modelu. Rozpúšťadlo, dichlórmetán sa odpaří v priebehu 30 sekúnd, pričom vzniká pevný film odlahčovacieho' prostriedku o hrúbke 0,2 mm. Příklad 2Acetylcellulose - 0.5 g - with the degree of substitution with acetyl groups 3 is dissolved in dichloromethane - 100 milliliter - with stirring at 20 ° C and add 0.05 grams of 1,2,3,4,6-penta-O- acetyl-D-glucopyranose and 0.5 g of copper powder with a particle size of 0.0.5 mm. Stir the mixture well by shaking and brush the surface of the model. The solvent, dichloromethane, was evaporated in 30 seconds to give a solid film of 0.2 mm thick stripping agent. Example 2
Riešenie podlá příkladu 1, s tým rozdielom, že acetylcelulóza o stupni substitúcie 0,6 sa použije o koncentrácii 3 g. I"1 a rozpustí sa v zmesi 60 ml dichlórmetánu a 40 ml octanu etylnatého a důkladnom premiešaním sa přidá 0,2 g 2,3,4-tri-O-acetyl-l,6-anhydro-beta-D-glukopyranózy a 0,5 g.l"1 měděného prášku o velkosti zrna 0,01 mm. Rozpúšťadlo sa odpaří v priebehu 1 minúty, pričom vzniká pevný film odlahčovacieho prostriedku o hrúbke 0,17 mm. Příklad 3The solution of Example 1, except that acetylcellulose with a degree of substitution of 0.6 is used at a concentration of 3 g. I ' 1 and dissolved in a mixture of 60 ml of dichloromethane and 40 ml of ethyl acetate, and 0.2 g of 2 is added thoroughly. , 3,4-tri-O-acetyl-1,6-anhydro-beta-D-glucopyranose and 0.5 µl of copper powder of 0.01 mm grain size. The solvent was evaporated for 1 minute to give a solid film of 0.17 mm thick release agent. Example 3
Riešenie podlá příkladu 1, s tým rozdielom, že sa použije ako rozpúšťadlo — 100 mililitrov — zmes dichlórmetánu, octanu etylnatého a acetónu v pomere objemu 1:1: : 1. Ako zmakčovadlo sa použije 0,05 g. to1 1,2,3,4,5,6-hexa-O-acetyl-D-glukopyranózy.The solution of Example 1, except that it is used as a solvent - 100 milliliters - a 1: 1 mixture of dichloromethane, ethyl acetate and acetone: 1: 0.05 g is used as a wetting agent. 4,5,6-hexa-O-acetyl-D-glucopyranose.
Rozpúšťadlo sa odpaří v priebehu 40 s pričom vzniká pevný film odlahčovacieho prostriedku v hrúbke 0,18 mm.The solvent is evaporated off over a period of 40 seconds to give a solid film of a release agent at a thickness of 0.18 mm.
Vynález má využitie v stomatologii pri přípravě detailných modelov pahýlov pri zhotovovaní fixných stomatologických náhrad.The invention has utility in dentistry in the preparation of detailed stump models for the manufacture of fixed dental restorations.
