Former dentist Kuang-Yi Ku created a prototype orthodontic retainer designed to improve the fellatio experience for the wearer's partner. After practicing dentistry for six years, Ku is now a student at Design Academy in Eindhoven, the Netherlands. His Fellatio Modification Project is a speculative design effort featured in the Science Gallery London's new exhibit Mouthy: Into the Orifice. The prosthetic consists of a custom orthodontic retainer with the top "embossed" with soft denture base material to create nubs on the roof of the mouth. From New Scientist:
Science doesn't have a great track record when it comes to incorporating human sexuality into research and practice. Dentistry, for example, considers three functions for the oral cavity: aesthetics, pronunciation and mastication. "There is another function, sex, which is never mentioned in the textbooks," says Ku. "I'm from the gay community and I realised that the medical school is a very patriarchal system, very serious, and the professors are very traditional, particularly in Asian countries. So I wanted to approach that relationship."
Instead of treating disease and restoring normal function to the mouth, Ku imagines dentists enhancing it along one particular line, the act of performing fellatio. To do this, he created retainers which offer a more intense sexual experience for your (male) partner.
