Provides an upwards and forward force on the palate, without touching the teeth and leaving enough space for proper tongue posture to assist the movement. The reaction force is splint between the forehead (70%) and the chin(30%). It also expands the palate from the bone exclusively as the appliance is NOT teeth anchored. I am getting about a total of 2kg of constant force on my maxilla. This is actually dozens of prototypes after the headgear I posted on SH four months ago. I have had ZERO progress as of now, and I blame it to the design of my old headgears which was subpar, delivering low amounts of forces inefficiently. I am actually wearing a newer version of this headgear, which is less bulky and more comfortable during sleep.
This is still the best proof I have that it can work. I talked to the author of that study and he said that the key is VERY HIGH force and VERY FREQUENT wear, although he doubts it's feasible on humans. In the study, they used 1kg of force (monkey's head is smaller than human's) and a 24h wear for 4 months. Skeletal changes are huge for four months, but it messed up the occlusion as his appliance was anchored to the molars.
