Abstract:
In order to provide a film-forming powder using hydroxyapatite which is a main component of teeth, or hydroxyapatite in which a color tone adjuster is blended, the powder being used in a jet-device for forming a film on a surface of a tooth by spraying the powder on the tooth, and being suitable for forming a film having a high hardness and extremely low solubility in acid in a short period of time, and suitable for forming a film of a powder conforming to the color tone of a tooth in a short period of time; a hydroxyapatite powder calcined in an inert gas atmosphere at 600 to 1350° C., a powder obtained by applying to the hydroxyapatite powder calcined at 600 to 1350° C. plasma irradiation, or plasma irradiation and mechanical energy, and additionally a film-forming powders obtained by blending color tone adjusters into these hydroxyapatite powders are produced.

Claim (Index 20):
The method for producing a film-forming powder according to  claim 11 , wherein a film thickness of a formed film is 30 \u03bcm or more, and Vickers hardness is 340 Hv or more when the powder is sprayed on a substrate under conditions of an inner diameter of a handpiece tip nozzle of 0.5 to 5.0 mm, a spray pressure of 0.2 to 0.8 MPa, a distance between a spray nozzle tip and a substrate of 0.1 to 3.0 cm, and a moving speed of the spray nozzle of 0 to 10 mm/s.
