Description

Предметом изобретени   вл етс  способ точного лить  зубных протезов , с учетом их усадки.The subject of the invention is a method for accurately casting dentures, taking into account their shrinkage.

Дл  точного лить  зубных протезов прибегают к различным приема: 1 , например, к подогреву формы, в которой отливаетс  деталь. Однако, эти способы не дают достаточной точпости лить .To accurately cast dentures, various techniques are used: 1, for example, to heat the mold in which the part is molded. However, these methods do not allow enough to pour.

В прилагаемом способе при1мен ютс  кварцевые модели, увеличивающиес  при обжиге в разных режимах соответственно коэффициенту расширени  того или иного металла. Это иозвол ет отливать протезы с весьма большой точностью.In the enclosed method, quartz models are added, which increase during firing in different modes according to the expansion coefficient of one or another metal. It is possible to cast dentures with very high precision.

Способ заключаетс  в следующем.The method is as follows.

По оттиску, сн тому обычным путем, изготовл ют контрольную .модель нз пласт.маееы или гипса. Затем гиисовокрахмальной композицией или гидроколлоидной .массой снимают с контрольной модели рабочий оттиск и ио нему изготовл ют кварцитовую модель. После этого кварцитовую модель обжигают. При этом она увеличиваетс  в объемеAccording to the print, in the usual way, a control model is made of nz plast.maeey or gypsum. Then the giisovokrammalny composition or hydrocolloid mass is removed from the control model of the working print and a quartzite model is made on it. After that, the quartzite model is burned. At the same time, it increases in volume

на величину усадки металла, из которого будет изготовлена деталь. Далее на кварцитовой модели конструируют из воска или пластмассы зубочелюстной протез. Затем по воековому протезу отливают протез из металла, который первоначально будет больше требуемой величин на столько, на сколько он в последующем уменьшитс  в результате усадки.the amount of shrinkage of the metal from which the part will be made. Next, on a quartz model, a dentition or dental prosthesis is constructed from wax or plastic. Then, the prosthesis is cast from the metal prosthesis from the metal, which initially will be more than the required values by as much as it subsequently decreases as a result of shrinkage.

По предлол енному способу кварцитовую модель можно сразу готовить по оттиску.According to the proposed method, the quartzite model can be immediately prepared from the impression.

Дл  изготовлени  кварцитовой модел берут кварцитовый сырец и смешивают его в фарфоровой ступке с гидролизированным этилсиликатом . Полученную тестообразную массу заливают на вибрационном столе в оттиск, подобно тому, как это делают при изготовлении модели из гипса.To make a quartz model, they take raw quartzite and mix it in a porcelain mortar with hydrolyzed ethyl silicate. The resulting dough mass is poured on a vibrating table in a print, just as it is done when making a model of plaster.

Предмет изобретени Subject invention

Способ точного лить  зубных протезов, отличающийс  тем, что, в цел х устранени  изменений размеров отливки вследствие усалТ.ки металла применены кварцитовые модели, увеличивающиес  при обжиге соответственно расширению металл-а при его плавлении.A method for precise casting of dental prostheses, characterized in that, in order to eliminate the changes in the dimensions of the casting due to the loss of metal, quartzite models are used, which increase during firing according to the expansion of metal-a when it is melted.
