Research Abstract |
The manufacturing of metal frames for dental prosthesis is associated with various problems. For instance, the casting of metal frames often results in internal defects and surface oxidation. In this study, to circumvent these limitations, we have performed experimental studies on superplastic manufacturing using fine-grained Ti–6Al–4V alloy obtained through hydrogen treatment (hydrogen absorption - quenching - hot rolling - hydrogen desorption). The outline of the metal frame was thus successfully manufactured by adopting suitable forming temperature, pressure, and holding time. The results obtained in this study substantiate the possibility of manufacturing metal frames for dental prosthesis by superplastic forming using fine-grained titanium alloy.
