摘要： The present invention is concerned with a process for the formation of dental restorations from glass-ceramic materials and the resulting dental restorations. In this invention a dental restoration is prepared by placing a glass ceramic material in a heat-pressure deformable crucible. Heat is then applied to the crucible in order to bring glass-ceramic material to a working range at temperatures above its liquidus temperature. The heat deformation properties of the crucible must be such that when the glass-ceramic material in the crucible is in the working range the crucible is heat-pressure deformable without rupturing. Once the glass-ceramic material is heated to its working temperature the crucible is brought into contact with a mold having a preformed cavity therein, the cavity being in the shape of the desired dental restoration. As the distance between the heated glass ceramic material and the mold is decreased, the crucible is deformed to form a seal with the mold thereby facilitating the injection of the molten glass-ceramic material into the mold cavity. The resulting dental restoration has superior optical esthetic and strength properties. The invention further includes the heat-pressure deformable crucible which is useful in the process of this invention and the related apparatus.
摘要翻译：本发明涉及从玻璃陶瓷材料形成牙科修复物的方法以及由此产生的牙科修复体。在本发明中，通过将玻璃陶瓷材料放置在热压可变形坩埚中来制备牙科修复体。然后将热量施加到坩埚上，以便使玻璃陶瓷材料在高于其液相线温度的温度下工作。坩埚的热变形性能必须使得当坩埚中的玻璃 - 陶瓷材料处于工作范围内时，坩埚可以在不破裂的情况下进行热压变形。一旦玻璃陶瓷材料被加热到其工作温度，坩埚就与其中具有预制空腔的模具接触，该空腔是所需的牙科修复体的形状。随着加热的玻璃陶瓷材料和模具之间的距离减小，坩埚变形以与模具形成密封，从而便于将熔融玻璃陶瓷材料注入模腔中。所得牙科修复物具有优异的光学美学和强度特性。本发明还包括在本发明的方法和相关设备中有用的热压可变形坩埚。
