Abstract: In a method for manufacturing a sintered body of the present invention, a feed stock including metal powder, a binder, and an organic material having a melting point lower than that of the binder is extrusion molding by using an extruder 1, so that an extruded body having a desired shape (cross-sectional shape) and dimensions is manufactured. In this method, a temperature of an extrusion side die 52 of an extrusion die 5 is lower than the melting point of the binder and higher than that of the organic material. Next, a debinding treatment (treatment for removing binder) of the obtained extruded body is performed. The debinding treatment is separately performed by a first process in a low temperature region and a second process in a temperature region higher than that in the first process. Subsequently, an obtained debounded body is sintered by baking in a sintering furnace, whereby the sintered body (metal product) is manufactured.

The abutment tooth model is formed so as to be slightly larger than the abutment tooth to the extent of the degree of shrinkage of the prosthetic restoration (green body) by taking the curing expansion upon molding and the thermal expansion upon sintering into account The abutment tooth is formed using a compound in which Ti powder or Tn alloy powder is contained as its main component, and the compound is built up onto the abutment tooth model 5 so as to have a desired shape, and thus obtained green body is subjected to a debinding treatment.

Abstract: In a method of manufacturing a sintered compact, a green body formed of titanium or titanium alloy powder is sintered in a furnace to produce a sintered compact. In this case, the green body is sintered under the condition that it is placed on a setter within a container formed of carbon materials.
