Five Divisions

The ASO group especially prides itself in its ability to design extremely high precision orthodontic devices, as well as on its prompt delivery of those devices to customers through its extensive network of sales offices.

Latent demand for orthodontic treatment is high in Japan although the practice is not as common as in western countries. We therefore wish to support framework that would prompt many more people to receive orthodontic treatment for its esthetic as well as functional benefits.
