Abstract
A method for manufacturing a dental implant including an abutment is manufactured through the following steps. A titanium molded body production step molds a titanium molded body composition to obtain a titanium molded body having one of male and female thread portions. A ceramic molded body production step molds a ceramic molded body composition to obtain a ceramic molded body having the other thread portion which makes thread coupling with the one thread portion. An assembling step assembles the titanium molded body and the ceramic molded body together so that the one thread portion makes thread coupling with the other thread portion, to obtain an assembled body. A degreasing step degreases the assembled body. A sintering step sinters the degreased assembled body.
Claims7
A method for manufacturing a dental implant including an abutment,
- wherein the abutment is manufactured through the steps comprising:
- molding a titanium molded body composition containing powder composed of titanium or titanium alloy and a binder, to obtain a titanium molded body having a male thread portion;
- molding a ceramic molded body composition containing powder composed of oxide-based ceramic and a binder, to obtain a ceramic molded body having a female thread portion which makes thread coupling with the male thread portion, and the female thread portion having pores;
- assembling the titanium molded body and the ceramic molded body together so that the male thread portion makes thread coupling with the female thread portion, to obtain an assembled body;
- degreasing the assembled body so that the binder contained in the titanium molded body and the binder contained in the ceramic molded body are removed therefrom to transform the titanium molded body into a titanium degreased body and to transform the ceramic molded body into a ceramic degreased body;
- and
- sintering the assembled body thus degreased to transform the titanium degreased body into a titanium member as a sintered body and to transform the ceramic degreased body into a ceramic member as a sintered body,
- wherein a part of the titanium or the titanium alloy is penetrated into the pores of the female thread portion after sintering the degreased assembled body, so that the ceramic member is firmly fixed and joined to the titanium member.
