A powder-jet deposition (PJD) process utilizes high-speed collision adhesion phenomenon. We developed a dental PJD system, which was capable of precisely controlled blasting of ultra-fine hydroxyapatite (HA) particle under room temperature and atmosphere. Using the PJD system, we succeeded to make HA films on tooth substrates using HA. The growth of the HA film is saturated after about 1 s. The hardness of the deposited HA films was similar to human enamel.
