Have you heard of Venlay with Jawtrac? How can it correct my underbite in 2 weeks?

I have a mild under bite and would like it corrected. I have a dentist who stated he can fix my bite in 2 weeks using a new type of dentistry called Jawtrac with venlays. Has anybody heard of this? If so, how could venlay correct a bite so quickly? My guess is that the teeth are built out to change the bite however am uncertain. I would appreciate any input if possible. Thank you
