I couldn't find it, perhaps with a URL or doi you could find it on sci-hub.pw or maybe at the library.

I found a description of the study:

Occlusal Changes Related to Cranial Bone Mobility, Libin, B.International Journal of Orthodontics, 20(1), March 1982

This study reports that the author was able to change the transverse dimension across the maxillae as measured at the second molars by two and sometimes three millimeters using craniosacral therapy

Thanks for searching @greensmoothies! Your reports about thumb pulling are what got me be back into researching osteopathic manipulation of the cranial sutures. I suspect that my torus palatinus is what has prevented me from feeling the kind of separation along my midpalatal suture that you describe and that I think I feel in my circummaxillary sutures when I press up and forward on the palate. I wonder if I could overcome this resistance with better technique and/or more diligent effort. It seems like it would be a good idea to loosen up the sutures manually before starting to use an expansion appliance.

I remember how upset I felt about how Mew said in what I think was the last q&a video about how it supposedly doesn't matter if growth occurs at the sutures vs remodelling. I suspect that it's not a matter of fast vs slow expansion so much as getting the suture pliable. In my entire mewing journey I saw the biggest changes with 3 weeks of @allixa thumb pulling method, after 5 years of mewing... main difference being as far as I can tell was mewing opens sutures minimally if at all, thumb pulling seemingly make them quite pliable. But the method is limited by the limits of the skull, seems to require use of a retainer device and there is a report of someone messing up their bite. I'd like to experiment further but need to gather more materials first and study more.

I'd also agree that making the midline suture pliable is very important, contributes significantly to results, and wish I realized this sooner. Such a waste all those years of hard mewing in comparison.

From my experience with making the midline suture pliable, once it reaches this state it's quite easy to open up, I once gently ran my finger along it and felt it open. So I'm inclined to believe the hard mewing isn't what's behind this effect, it just so happens to be how you're maintaining it. Thanks for sharing your result.

I'm not too familiar with cranial sacral therapy, but I noticed they have quite a lot of papers published in various journals, such as the Journal of the American Osteopathic Association, about separating cranial sutures, and would like to review what I can to see what I might glean from them in my spare time. Lately I've been looking at such for ideas on how to optimise my thumb pulling technique. There is also another book I'm reading which ties in to Dr. Nemechek's work somewhat (who started his career as an osteopath) called "The Polyvagal Theory: Accessing the Healing Power of the Vagus Nerve" written by a cranial sacral therapist. In the beginning of the book there is an account of a patient with a bulging vertebrae which was quickly slipped back in to place once the author did some kind of manipulation that supposedly put the body in to a mode where it's feeling receptive, safe and socially engaged (described much like how Plato urges people to get in to parasympathetic mode with the use of light forces to move the maxilla up and forwards, although there's a more in-depth and sophisticated understanding of this phenomena now under the Polyvagal Theory)

With that said, I'm not totally sure how cranial sacral therapy works and believe it's classified as a pseudoscience in part because the use of 5g of force to move cranial bones hasn't been reproduced by professionals outside the various fields such as cranial sacral therapy. I don't think my ability to (as per my belief) separate the midpalatal suture very easily the one time I did was necessarily a kind of cranial therapy success, but rather it seems (based on my experience and belief) that sutures can become quite pliable after some time of being pried open. I've since come to believe this pliability of the suture(s) is a noteworthy consideration when we chose a device and with mewing.

I'm trying to figure out the best method of manual manipulation to increase the plasticity of the sutures, especially my intermaxillary suture, which I believe is less compliant because of my torus palatinus. I'm wondering what motions to use, how much force to apply, and how frequently to do it. I've experimented with the methods described in the thumb pulling thread, but maybe not as diligently as would be required to get results. It sounds like you're saying that you believe more force is necessary than the light pressures typical of craniosacral therapy.
