First one is the upper Jaw plate which I purchased, second link is the full upper jaw stretching plate which has extra screws by the rear molars. If I would buy again I would buy the full upper jaw stretching plate. Ive also linked to a combo deal which comes with a lower jaw plate. Cant comment on lower jaw expansion its really difficult to expand the lower jaw so probably not worth it. As you advance and swing the maxilla upwards the lower jaw naturally comes up anyways and makes up for the distance (So i've been told).

You wouldn't need a retainer if you had really good oral posture. Your tongue to the palate would support the teeth.

yeah totally agree, bought the upper jaw plate as a starter.

I'm a bit dubious about the stretching plate, especially if you were to do it without the help of a dentist. It would push the front teeth forward, but also push the rear teeth back. If you were to buy the stretching plate because you wanted to use the stretching feature, Id say to just face pull with the upper jaw plate.
