Geller announced and released artificial teeth in 2000, which they had been developing since around 1993. Until now, Geller had not been satisfied with the shape and color of commercially available artificial teeth. At that time, when arranging artificial teeth for dentures, he deliberately selected artificial teeth that were slightly larger and arranged their shapes to create and arrange artificial teeth that matched the patient's personality.

However, there were still areas where the shape of the artificial teeth was less than what he had imagined, so he was not satisfied, and the interdental papillae in the gums could not be shaped to match his age.

So he developed the first artificial teeth that improved upon them. Unlike other artificial teeth, the color tone is bright, natural, and beautiful.
