Description
Дл мостовых работ в зубоврачебной технике примен ют фарфоравые зубы типа Стилли, и дл прикреплени их к мосту требуютс металлические защитные пластинки; массовое приготовление форм дл отливки пластинок предлагаетс призводить при помощи гипсового блока, подготовл емого разрезкою при помощи предлагаемого прибора. На фиг. 1 предлагаемый прибор изображен Б перспективе; на фиг. 2 изображены ножи к прибору; на фиг. 3 изображен прибор, наложенный на отлитый гипсовый блок; на фиг. 4- перспективньш вид подготовленного разрезкою гипсового блока; на фиг. 5-отделенна от блока пластинка дл формы; на фиг. 6-та же пластинка , подготовленна воском, и на фиг. 7 изображена отлита пластинка и вид с задней стороны фарфорового зуба типа Стилли. доски а (фиг. 1 и 3) с параллельными прорезами 1, которые с одного конца / несколько расширены. По верху с трех сторон пластинка окаймлена бортами с. выступы которых по продольным сторонам расположены параллельно прорезам / и служат направл ющими дл продвижени бруска е (фиг. 2) с резаками d по чкслу прорезов /. Брусок е накладываетс на доску о так, чтобы резаки вошли в прорезы / и выступали за нижнюю поверхность доски, котора в таком виде накладываетс на вылитую на бумагу массу из гипса в смеси с пемзой или другим употребл емым дл отдивки материалом (фиг. 3). и когда масса несколько затвердеет. брусок с резаками продвигают вдоль прорезов; / доски до конца прорезов, а по затвердевании массы прибор снимаетс (фиг. 4), и затвердевший блок распиливаетс на пластинки (фиг. 5). коПрибор состоит из металлической Porcelain Stilly type teeth are used for bridge work in dental technology, and metal protective plates are required to attach them to the bridge; mass preparation of forms for casting plates is proposed to be manufactured using a gypsum block prepared by cutting with the help of the proposed device. FIG. 1, the proposed device is depicted in B perspective; in fig. 2 shows the knives to the device; in fig. 3 shows an instrument superimposed on a cast gypsum block; in fig. 4- a perspective view of a plaster block prepared by cutting; in fig. 5-separated from the block plate for the form; in fig. 6 is the same waxed plate and in fig. 7 shows a molded plate and a view from the back of a porcelain tooth like Stilley. boards a (Fig. 1 and 3) with parallel notches 1, which at one end / slightly expanded. On the top of the three sides of the plate bordered by the sides. the protrusions of which are arranged along the longitudinal sides parallel to the cuts / and serve as guides for advancing the bar e (Fig. 2) with the cutters d along the cuts of the cuts /. Bar e is superimposed on the board so that the cutters enter the slots / and protrude beyond the bottom surface of the board, which in this form is superimposed on a mass of gypsum poured on paper mixed with pumice stone or other material used for chipping (Fig. 3). and when the mass hardens somewhat. bar with cutters advance along the cuts; / boards until the end of the cuts, and when the mass is solidified, the device is removed (Fig. 4), and the solidified block is cut into plates (Fig. 5). The instrument consists of a metal
