СПОСОБ ИЗГОТОВЛЕНИЯ КЕРАМИЧЕСКОГО ПРОТЕЗА  METHOD FOR PRODUCING CERAMIC PROSTHESIS
Изобретение относится к медицине, а именно к стоматологии, и может быть использовано в ортопедической стоматологии при изготовлении керамических протезов. The invention relates to medicine, namely to dentistry, and can be used in orthopedic dentistry in the manufacture of ceramic prostheses.
Известен способ изготовления керамических протезов путем получения протеза зуба методом прессования прессовочной керамики, в частности дисиликата лития. Протез изготавливают меньше заданных размеров для возможности нанесения слоя, имитирующего эмаль зуба. Далее проводят домоделирование протеза путем нанесения на поверхность протеза слоя керамических красителей с последующим глазурованием его поверхности. /Руководство по изготовлению керамических протезов «Техника окрашивания 2010 г. С. 24-39», е. max Press LT - /.  A known method of manufacturing ceramic prostheses by obtaining a tooth prosthesis by pressing pressed ceramics, in particular lithium disilicate. The prosthesis is made smaller than the specified size for the possibility of applying a layer that mimics the tooth enamel. Next, the prosthesis is home-made by applying a layer of ceramic dyes to the surface of the prosthesis, followed by glazing of its surface. / Guidelines for the manufacture of ceramic prostheses “Staining Technique 2010. P. 24-39”, e. Max Press LT - /.
Недостатком известного способа является недостаточная точность изготовления протезов.  The disadvantage of this method is the lack of accuracy in the manufacture of prostheses.
Техническим результатом данного изобретения является повышение точности изготовления керамических протезов и повышение их эстетики.  The technical result of this invention is to increase the accuracy of manufacturing ceramic prostheses and increase their aesthetics.
Технический результат достигается тем, что в способе изготовления керамического протеза путем получения протеза зуба с размером меньше заданного с последующим домоделированием и глазурованием, отличительной особенностью является то, что домоделирование протеза ведут с использованием моделировочного материала с последующим запаковыванием его в кювете паковочной массой, после затвердевания паковочной массы проводят выжигание моделировочного материала и охлаждение кюветы, образующееся пространство между поверхностью протеза и кюветой заполняют керамическим материалом в виде водной суспензии, который уплотняют, просушивают, прессуют, выпаковывают и глазуруют.  The technical result is achieved by the fact that in the method of manufacturing a ceramic prosthesis by obtaining a tooth prosthesis with a size smaller than the specified one, followed by home modeling and glazing, a distinctive feature is that the home prosthesis is modeled using modeling material, followed by packing it in the cuvette with the investment material, after the investment package has hardened. the masses burn the modeling material and cool the cuvette, the resulting space between the surface of the prosthesis and the cuvet that is filled with a ceramic material in aqueous suspension, which is compacted, dried, pressed, and vypakovyvayut glaze.
Способ осуществляют следующим образом: Стоматологический протез изготавливают в уменьшенном на 0,6-0,9 мм меньше заданного размера виде (так называемый каркас), чтобы осталось место для нанесения слоя, имитирующего эмаль зуба. Его изготавливают любым известным на сегодняшний день методом, в числе которых могут быть упомянуты прессование прессовочной керамики, например, дисиликата лития, напрессовывание прессовочной керамики на металлический или оксид-циркониевый каркас, фрезерование и т.п. После этого наносят керамические красители для получения индивидуальных характеристик зубов и спекают в печи для обжига стоматологической керамики. Далее проводят домоделирование протеза путем нанесения на полученную поверхность моделировочного материала (воск, пластмасса), который соответствует эмали протеза. The method is as follows: A dental prosthesis is made in a form that is reduced by 0.6-0.9 mm smaller than a predetermined size (the so-called skeleton), so that there is room for applying a layer imitating tooth enamel. It is made by any method known today, including pressing extruded ceramics, for example, lithium disilicate, pressing extruded ceramics onto a metal or zirconium oxide frame, milling, etc. After that, ceramic dyes are applied to obtain individual characteristics of the teeth and sintered in a kiln for firing dental ceramics. Next, the prosthesis is home-made by applying modeling material (wax, plastic) to the surface obtained, which corresponds to the enamel of the prosthesis.
Устанавливают на моделировочном материале литники и запаковывают в кювету для прессования стандартной паковочной массой.  The sprues are mounted on the modeling material and packed in a cuvette for pressing with a standard investment material.
После затвердевания массы её помещают в муфельную печь и разогревают для выжигания моделировочного материала с последующим охлаждением до комнатной температуры. Вследствие выжигания моделировочного материала образуется пространство между стенкой протеза и кюветой. По литникам вносят керамический материал в виде водной суспензии, которую уплотняют. Кювету помещают в муфельную печь и просушивают. После этого переносят в прессовочную керамическую печь, вставляют плунжер из оксида алюминия и проводят прессование. Полученную конструкцию охлаждают, выпаковывают пескоструйным аппаратом, срезают литники и механически обрабатывают при помощи стоматологических абразивов. После этого стоматологический протез глазуруют в печи для обжига стоматологической керамики и вносят, если необходимо, коррекцию по цвету или форме.  After the mass has solidified, it is placed in a muffle furnace and heated to burn modeling material, followed by cooling to room temperature. Due to the burning of the modeling material, a space is formed between the wall of the prosthesis and the cuvette. On the sprues make ceramic material in the form of an aqueous suspension, which is compacted. The cuvette is placed in a muffle furnace and dried. After that, it is transferred to a ceramic pressing furnace, an aluminum oxide plunger is inserted and pressing is carried out. The resulting structure is cooled, packaged with a sandblasting apparatus, the sprues are cut and machined with dental abrasives. After that, the dental prosthesis is glazed in an oven for firing dental ceramics and, if necessary, a correction is made in color or shape.
Пример.  Example.
Протез зуба изготавливают с уменьшением на 0,7мм по сравнению с будущим протезом из дисиликата лития (IPSE max Press ivoclar-vivadent) методом прессования. После окраски керамическими красителями протез домоделируют воском и запаковывают в прессовочную кювету паковочной массой IPS Press Vest ivoclar vivadent. Кювету помещают в муфельную печь и выжигают при конечной температуре в 700 °С. Затем ее медленно охлаждают до комнатной температуры. Разведённую водой до суспензии керамическую массу (IPSE max Ceram ivoclar vivadent) заливают по литниковым каналам. Керамический материал заполняет пространство между протезом и кюветой, после чего его уплотняют. The tooth prosthesis is made with a decrease of 0.7 mm compared to the future lithium disilicate prosthesis (IPSE max Press ivoclar-vivadent) pressing method. After staining with ceramic dyes, the prosthesis is homemade with wax and packaged in a compression cuvette with IPS Press Vest ivoclar vivadent. The cuvette is placed in a muffle furnace and burned out at a final temperature of 700 ° C. Then it is slowly cooled to room temperature. The ceramic mass (IPSE max Ceram ivoclar vivadent) diluted with water to the suspension is poured through the sprue channels. Ceramic material fills the space between the prosthesis and the cuvette, after which it is compacted.
Прессовочную опоку просушивают при 300 °С в муфельной печи в течение 40 минут, после чего переносят в керамическую прессовочную печь (ЕР 600 фирмы Ivoclar vivadent) и прессуют со следующими параметрами:  The pressing flask is dried at 300 ° C in a muffle furnace for 40 minutes, after which it is transferred to a ceramic pressing furnace (EP 600 from Ivoclar vivadent) and pressed with the following parameters:
- начальная температура — 300 °С;  - initial temperature - 300 ° C;
- конечная температура — 750 °С;  - final temperature - 750 ° C;
- время прессования — 60 минут.  - pressing time - 60 minutes.
Полученный протез распаковывают пескоструйным аппаратом, после чего проводят глазуровку и докраску (глазурь и краски фирмы Ivoclar) в печи для обжига стоматологической керамики при температуре 725 °С.  The resulting prosthesis is unpacked using a sandblasting apparatus, followed by glazing and painting (glaze and paints from Ivoclar) in an oven for firing dental ceramics at a temperature of 725 ° C.
