Latest Patents

Ohta holds a patent for a dental gold alloy with age-hardenability at intraoral temperature. This dental gold alloy is designed to be soft enough for the adjustment of a patient's occlusal condition. It is age-hardenable over time at temperatures typically encountered within a patient's oral cavity. The alloy features a single-phase structure that imparts improved corrosion resistance. Specifically, the dental gold alloy consists of 82-67% by weight of gold, 18-33% by weight of copper, and 2-8 atomic percent of an age-hardening accelerator, which includes metals such as gallium, aluminum, and zinc. The alloy undergoes a solution treatment by heating at 670-700°C and quenching in water.
