I have also read some posts on various forums for using HGH to accelerate bone remodeling.
And I do expect to have results, as I only need a few millimeters (like 2 or 3) in the mandible for all teeth to fit in without crowding.

People your age achieve results from Mewing all the time so it's not likely too late for you. That's as specific answer as I can give.

I used the Pythagorean theorem to calculate the hypotenuse of ThaGangsta's ideal dental arch. Then I rolled my neighbor's magic dice until I hit 6 thrice in a row and converted the amount of tries it took into percentages.

How did you calculate that ideal?

Using that logic, I have an intermolar width of 39-40 mm and I'm 17.  How likely is it that my palate has fused?  What is the genetic ideal anyway?
47% chance. Your unique genetic potential is 53 mm when measured at the second molars. Good luck.

Why are statements from those in the orthodontic field on the midpalatal suture fusion so inconsistent?  Some say it fuses to the mid to late teens, some say by mid 30s, some say late in life, and some say that they never fuse.

The problem is that the rate seems to be highly individual:

Adults had great variability in sutural maturation, as corroborated by other studies.9,11 We found that 53% of the adults were in stage E, 31% were in stage D, 13% were in stage C, and 1 subject (3%) was in stage B.

One factor that could possibly influence the speed of sutural maturation is pre-existing palatal width. I wouldn't be surprised if palates closer to the genetic width potential fused earlier than narrow palates with plenty of room for growth. It's a shame that inter-molar width wasn't taken into account in above study.

It's interesting to note that the recommended resting spot for the tip of the tongue seems to be located exactly at the meeting point of the incisive sutures (2) and the mid-palatal suture (7). I wonder whether the incisive sutures (or any other sutures apart from the mid-palatal suture for that matter) are relevant to palate expansion as an adult though:

¨
On mid palatal suture:

Quote
The ossification of the maxilla is much debated. There is no argument to the fact that this is a bone that forms in connective tissue anterior to the cartilaginous nasal capsule. The debate is over the number of centers involved in maxillary ossification and whether a separate element, the os incisivum - the homologue to the premaxilla, is incorporated into the development. The simplest scenario involves a single ossification center arising in the body of the maxilla and spreading to form the entire bone. Other workers suggest that additional centers, up to two, form in the incisor region corresponding to the premaxillary bone of other mammals. These centers appear during the sixth embryonic week and join by the third month. By late fetal life there exists no clear indication of separate centers on the facial side of the bone however, on the palate approximately 25 percent of skulls retain a suture line at the junction of the two centers. This suture is retained in adult skulls.

On incisive suture:

Quote
The incisive suture is a variable suture in the adult skull that occurs on the palatal surface of the maxilla where the premaxillary bone joins the maxilla. This suture typically ossifies as a synostosis and no remnant of a suture remains. [/b]When present it is weakly serrate in form.

We know growth can occur at sutures with pressure applied over time. We know that sutures do not solidify until very late in life, and sometimes never at all. Here is an image of the sutures on your palate (the jagged lines).



Unsurprisingly, the palate expanders used everywhere have their expansion screws along one or more of these sutures. Now we average folk can see where the actual expansion is happening and by what function.

#7, the mid maxillary suture, can be expanded by about 1mm a week. We do not know the proper rates of expansion for the others yet, it may differ
