For the actual positioning: it is positioned as illustrated in the figures, the lower jaw is pulled right back, so that it is completely inconvenient. Who wants to imagine the result can a try to pull his jaw a few hours back. If that like, which can as well draufschlagen still NEN star.
Will it against a vertical position creates an unpleasant pressure on the tooth surfaces, because the denture is then strongly compressed. Well, I agree, is indeed the intention. Just so it holds so (and does not slip on the position in the figure), it must be pulled so tight that it effectively prevents any sleep.
Generally, the problem is: it sits firmly reasonably, is so uncomfortable that you have no chance to sleep. Sitting there so that you could sleep is so loose that it falls off completely. The fact that the belt is very narrow, the pressure is on to a small area, thus much too strong exercised.
Have too many nights in a row trying to get used to it, but eventually abandoned that I ever again get sleep.
The pierced poor last are too small.
