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

Neuromuscular Dentistry utilizes jaw tracking and can be used to establish a bite.  I strongly eendorse tthe use of Jaw Tracking for doing reconstructions.  This is not a new type of dentistry.
I suggest that treatment be divided in phases.  Phase 1 try out the bite and try out for a while before finalizing during Phase 2.  This is especially true if you are treating TMJ dysfunction or chronic pain disorders
There are many advantages to no-preparation dentistry but it is not suitable for all mouths.
That said the use of neuromuscular dentistry is an ideal way to reconstruct the mouth.
