Doctors Garry and Prior used a low frequency T.E.N.S. unit to find the neuromuscular mandibular position before taking the construction bite. Vertical elastics in the canine region produce a propioceptive response when the patient opens his mouth during the night. This appliance is a further modification of the Garry-Prior device. A full coverage splint replaces the framework. The occlusal surfaces are accurately refinished for full contact.
Maximum retention is obtained with multiple ball clasps both on the upper and lower arch.
