Abstract

In this study, orthodontic brackets were manufactured via Metal Injection Molding (MIM) using 17-4 PH stainless steel. A feedstock of 17-4 PH powder with a polyacetal/polyethylene binder was shaped, followed by catalytic debinding and sintering in a hydrogen-nitrogen atmosphere at 1260 °C. The sintered brackets exhibited a linear expansion factor of approximately 17%. After precipitation hardening, the brackets achieved a Vickers hardness of 357 HV and a density of 6.6 g/cm³, with a low porosity level of 1.3%. The results demonstrate that the MIM process combined with subsequent heat treatment can produce 17-4 PH stainless steel dental brackets with mechanical properties comparable to commercially available products, validating the manufacturing route.
