The present invention provides a powder for film formation, which is used in a device that forms a film on the tooth surface by spraying powder onto the tooth surface; the powder for film formation of the present invention is used as a main component of teeth And add the hydroxyapatite of the color adjustment agent, the hydroxyapatite is suitable for forming a film with high hardness and extremely low solubility to acid in a short time, and suitable for forming a powder suitable for tooth tone in a short time Body film; In order to provide the film forming powder of the present invention, hydroxyapatite powder is sintered at 600~1350℃ under an inert atmosphere, and electricity is applied to the hydroxyapatite powder sintered at 600~1350℃ A powder is obtained by slurry irradiation, or plasma irradiation and mechanical energy, and further, a hue adjuster is added to the hydroxyapatite powder to produce a powder for film formation. |
