Is a third jaw surgery revision possible?

A third jaw surgery is possible. For this to be successful, there needs to be a clearly defined goal that is agreed upon between you, your surgeon, and your orthodontist. The surgery needs to be performed by an expert surgeon.
In almost every case, attempting to camouflage an open bite with orthodontics is a bad idea because this will result in further instability of the bite. Camouflage orthodontics creates biomechanical instability because the roots of the teeth are not correctly placed in the bone, and the forces of the teeth during biting will create further instability. If you have ever attempted to hammer a nail slanted in a piece of wood, you will notice that hammering the nail tends to make it more slanted. Related to this is the fact that camouflage orthodontics does not correctly place the roots of the teeth in the bone optimally, leading to a downward spiral, including loose teeth, further bone loss, and further instability of the bite.
There is no substitute for a proper diagnosis, appropriate diagnostic imaging with the CT scan, including teeth and bone cross-sections, experienced expert orthodontic and surgical care, and a clearly defined plan. Anything short of this will inevitably lead to wasted time, money, and heartache. If you are not in a financial or emotional position to undergo another surgery and do not have the support of people who care about you (who, in almost all cases, will ALSO need to be educated by your surgeon about why you are doing this), it is far better to remove the braces, have your orthodontist make retainers for you, and wait until you are in better position in your life.
I wish you well.
