Titanium metal has been used as a dental prosthesis material because of its good biocompatibility. Most of the dental prostheses made of titanium metal have been manufactured by precision lost-wax casting. However, this is not always the best manufacturing process for low-strength products or a long processing time. The authors have developed a net shape forming process for fabricating a precision thin-walled cylindrical can made of titanium powder using a DC pulse resistance sintering apparatus. In the present paper, the DC pulse resistance sintering process of pure titanium powder has been introduced to develop a net shaped dental prosthetic crown. As a result, it has been confirmed that the titanium dental prosthetic crown developed by the process has high density, sufficient hardness and adequate dimensional accuracy.
