    • A method of producing ceramic crowns by depositing a dental ceramic material on the surface of a ceramic core and baking the same, characterized by comprising the steps of preparing an assembly of a crucible former having a column in the form of a bottomed cylindrical body provided with a fitting recess in the central region of the upper surface of the central portion thereof, a wax pattern attached to the fitting recess and having a solid lubricant applied to the surface thereof, a ring with a back layer member engaging the bottomed cylindrical body, and a buried member, removing the crucible former from the assembly, burning the wax pattern to form a mold, filling a ceramic material in the mold, and pressing the same by a plunger, thereby molding the ceramic core. According to this method, full ceramic crowns of high quality can be efficiently produced in a short time.
    • 一种通过在陶瓷芯的表面上沉积牙科陶瓷材料并烘烤陶瓷牙冠的方法,其特征在于包括以下步骤:准备坩埚形成器的组件,所述坩埚成形器具有带底筒圆柱体形式的柱, 在其中央部的上表面的中央区域的嵌合凹部,附着在嵌合凹部上并具有涂布在其表面的固体润滑剂的蜡图案,具有与底部圆筒体接合的背层构件的环和 埋置构件,从组件中取出坩埚形成体,燃烧蜡图案以形成模具,在模具中填充陶瓷材料,并通过柱塞将其压制,从而模制陶瓷芯。 根据该方法,可以在短时间内高效率地生产高质量的全陶瓷冠。
