Yes, in a few forms. Exogen makes a device but it's not indicated for the face. Acceledent, as I mentioned, is available to orthodontists already and I plan to use it with my braces. OrthoPulse is under trial now but I hear it looks comparably good.
The only facial applications I've seen are non-surgical treatment of hemifacial microsomia and to speed up implant integration. It seems like it could be used to accelerate healing after jaw surgery but no surgeons I met had heard of it. I wouldn't want to be the guinea pig, at least use a real guinea pig first. Or reduce non-union rate, strengthen bond, and avoid notching in addition to stem cells. Pretty cool revolutionary technologies.
With newer less invasive cuts, improvements to biodegradable plates and screws (like the silk ones demonstrated at Tufts recently), and medication to stimulate nerve growth, jaw surgery could become considerably less invasive in 10-20 years at least.
