Own a lot of patented technologies and the world’s highest quality

High technical power and high quality

Provide more comfortable dental prosthesis for you with the world's largest artificial teeth

Our artificial teeth are famous for their hardness. The Vickers hardness is 45. The hardness is 1.5~2 times than the hardness of the artificial teeth regularly marketed in the world, so they are far better than regular artificial teeth. Without doubt, the teeth at such hardness are still poorer than natural teeth. However, the world’s hardest artificial teeth are very durable. The original molds can be preserved for a long time, so patients can enjoy the conformable false teeth for a long time, which is widely welcomed by them.

Titanium implanted teeth newly developed with patented technology

After we achieved the success in the artificial teeth, we are now developing the implanted teeth through all efforts. Our new “μ-ONE HA implanted teeth” are our confident work that we develop with the sputtering technology and have obtained the patent. Through applying a film of 1~2μm solid hydroxylapatite (HA) crystal to the surface of fixing device (embedded in maxilla during surgery) for titanium implanted teeth, the durability is considerably improved. Moreover, it can allow the rapid growth of bones so as to help improve the QOL of patients.
