Development of dental powder jet deposition handpiece utilizing particle feed mechanism of tablet cutting

Powder jet deposition (PJD) is a coating technique that can form films under conditions of room temperature and atmospheric pressure. We have developed a dental treatment with this technique to form hydroxyapatite (HA) films on human teeth. However, the micron-order HA particles show a high degree o...

Summary:Powder jet deposition (PJD) is a coating technique that can form films under conditions of room temperature and atmospheric pressure. We have developed a dental treatment with this technique to form hydroxyapatite (HA) films on human teeth. However, the micron-order HA particles show a high degree of cohesiveness, which results in residual particles on the pipe transporting the particles from the particle tank to the handpiece. Therefore, we developed a dental PJD handpiece without a particle-transporting pipe, utilizing a particle feed mechanism of tablet cutting. The experimental results showed that the developed handpiece formed HA film without residual particles on the pipe.
