How long is the history of Japanese wooden dentures?

The Japanese oldest wooden denture was the one worn by a nun, commonly known as Hotokehime, at a temple in Wakayama City.
Given that she passed away in 1538, wooden dentures were already made at the end of the Muromachi period (1338 – 1573). In the Edo period, denturists came into existence; Ono Gennyu made a wooden denture for Yagyu Munefuyu, a swordplay coach for the Tokugawa Shogun. It is said that sculptors of wooden Buddhist statues, netsuke artists and other wood carving artisans switched jobs and became denturists. To make a wooden denture, its impression was made using beeswax and it was carved using a technique of fitting it to the chin.
