Since Hi-Dental Japan's founding in 1971, we have engaged in the development and manufacture of a wide range of dental laboratory materials while ensuring high safety standards through applicable laws and regulations, and our quality is regarded not only in Japan but also highly in the United States and other Asian countries. Meanwhile, since Denken's founding in 1969, we have built our position as a manufacturer of research-use electric furnaces based on thermal control electronics technology, and through this applied technology we have earned the support of many dental technicians in Japan and abroad as a global manufacturer of dental laboratory equipment.
From now on, we will bring together the best of our extensive experience and refined technology, cultivated over many years, to provide not only conventional equipment but also new system products such as digital equipment to customers both domestically and internationally.
