A manufacturing method for a prosthetic apparatus for dental purpose according to one aspect of the present invention includes: acquiring scan data of a model that is a reproduction of at least a part of an inside of an oral cavity of a patient; creating shape data of a shaped body for dental purpose on a basis of the scan data; producing a shaped body on a basis of the shape data; covering at least a part of the shaped body and at least a part of a model with film, the shaped body attached to the model; releasing air in a part covered with the film to deform the film and bring the shaped body into close contact with the model; and curing the shaped body in a state where the shaped body is in close contact with the model.

Post-curing method after optical shaping of 3D printer

To provide a dental porcelain paste which can maintain maintaining the paste state and have excellent application property for a long period of time and hardly causes carbonization or bubbles due to the influence of an organic component or a polymer component during firing. The present invention provides a dental porcelain paste for preparing a dental prosthesis device, comprising: 50.0 to 80.0 wt. % of a glass powder (a) having a maximum particle diameter of 100 &#x3bc;m or less and an average particle diameter of 1 to 20 &#x3bc;m, 0.5 to 10.0 wt. % of a hydrophobized fine particle silica (b) having an average primary particle diameter of 1 to 50 nm, and 10.0 to 49.5 wt. % of an organic solvent (c) having a boiling point it is within (bp) of 100 to 300&#xb0; C.

Dental porcelain paste superior in application property

To provide a glass composition which can be used for a dental porcelain or a dental ceramics coloring material, and has low temperature meltability, acid resistance and preservation stability under the humid environment which are required for a dental porcelain or a dental ceramics coloring material, and a dental porcelain and dental ceramics coloring material which contain the glass composition of the present disclosure. To provide a low melting glass composition with softening point (Ts) less than 600&#xb0; C. comprising as a component; SiO: 55.0 to 75.0 wt. %, BO: 6.1 to 12.0 wt. %, AlO: 2.0 to 8.0 wt. %, ZnO: 2.0 to 8.5 wt. % and two or more kinds of alkali metal oxide: 10.5 to 20.0 wt. %.

Low melting point glass composition excellent in water resistance
