We study here the possibility of the computer aided manufacturing of dental prostheses with the use of conventional dental materials of superior aesthetic properties. In particular, the automated of porcelain fotming utilizing the computer controlled powder injection system is investigated, and obtained the following results :1. Outline of the system. The manufacture of 3 dimensional shapes of prostheses is realized by the repeated unit injection of the micro drops of porcelain powder with ca. 0.5mm. The system is composed by the injection machine, and the XY stage which control the position of the work under the nozzle of the injecting machine.2. Injection machine. Porcelain powder, which corrected by the reciprocating wiper to the circular sink, is pushed out by the steel rod through the nozzle, whose inner diameter is 0.3mm, located at the bottom of the sink. The device assembled enable us to inject small drops of porcelain powder constantly.3. Distillled water injection machine. This device is realized by the use of the component of the commercially available ink-jet printer.4.Results. The amount of the porcelain powder injected is about 50 micro gram, and that of distillled water is about 40 micro gram. The repeated and prolonged injection is possible. The computer control of XY stage resulted the scanning of the work to realize the multi-layred injection. The accuracy of the location of the injected drops is about 1mm.5. Conclusion. The appropriateness of the desig of the system is verified, although some improvent in the accuracy of the system seems necessary.

我们在此研究了计算机辅助制造具有优越美学性能的传统牙科材料的可能性。重点研究了利用计算机控制的喷粉系统实现陶瓷成型的自动化，取得了以下成果：1、陶瓷成型的自动化程度；系统概述。通过反复单位注射约0.5mm的瓷粉微滴，实现了三维假肢形状的制造。该系统由注塑机和控制工作在注塑机喷嘴下位置的XY工作台组成。注射机。经往复刮水器校正到圆形水槽的瓷粉，由钢棒通过水槽底部内径0.3mm的喷嘴推出。装配好的装置使我们能够不断地注入小滴瓷粉。蒸馏水注射机。该装置是通过使用市售喷墨打印机的组件来实现的。瓷粉注入量约为50微克，蒸馏水注入量约为40微克。重复和延长注射是可能的。计算机对XY工作台进行控制，对工件进行扫描，实现多层注入。注射液滴的定位精度约为1mm。结论。虽然系统的精度似乎还需要一些改进，但系统设计的适当性得到了验证。
