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.

用于牙科假体的金属框架的制造与各种问题有关。例如，金属框架的铸造通常会导致内部缺陷和表面氧化物。在这项研究中，为了规避这些局限性，我们使用了通过氢处理获得的细粒Ti -6al – 4V合金（通过氢处理（吸收氢 - 淬灭 - 热滚动 - 氢 - 解吸）获得的高颗粒制造实验研究。因此，金属框架的轮廓成功地通过适当的形成温度，压力，压力，压力，压力，压力和持有时间来成功制造。在这项研究中获得的结果证实了通过使用细粒钛合金形成超代形成的牙齿假体金属框架的可能性。
