What do you think about 3d printed appliances that could be put in the mouth, potentially all night long, to improve tongue posture and etc?

I feel like for a lot of people with narrow and vaulted palates it would be beneficial to have more grip on the front of the palate. My tongue is simply too narrow/lacks the pressure to expand my front palate. The result is is that my palate is at a pretty good position on the back, but is very high-arched at the front.

My lips being disproportionately small compared to my nose and face proves this as well(lip length is strongly correlated to inter-canine width). As well as my IMW being higher than average, but inter-canine width lagging behind.

Maybe I should work on my mewing technique though, I may be tensing my tongue too much making it too narrow at the front. I feel like even 3 years later I am still discovering the muscular control around the tongue.

Bone remodeling to correct maxillary deficiency after growth cessation

This study has always been of interest to me.  It's not a perfect case, since part of how they made occlusion again is by removing lower premolars.  But still, the ceph traces and change in angle of A and B point are both compelling for non-surgical treatment.  These are similar results to what I'm hoping my provider can be able to achieve.

Has anyone found a full text link for this one?  I'd be curious to read it.

@admin This is great - thanks for the PDF!  I had read the original research that he and Haas published, but I didn't know he authored a "follow-up" report.

So basically, he's saying that maxillary expansion in adults can be done non-surgically ... and to expect it to be mostly alveolar remodeling, not really much happening at the suture.  This is good, because he and Haas kind of left things "up in the air" a bit in his previous study.

It was good to see him mention "appositional" bone growth in this research, as that is a process that occurs throughout life ... not just in the "growing years".  It's also interesting that he calls out that even in kids, it seems as though palate expanders are only getting 40-50% skeletal growth and the rest is dental/alveolar even in that best-case scenario.

Also good that he noted that most of the other risks always discussed ... don't seem to be an issue ... as well as long-term stability seems to be achievable years later.  And interesting that he found that a 0.25mm turn every three to five days seems to be what an adult can cope with ... Vivos DNA advocates a 5-7 day schedule, but I know some patients (including me) who have had that advanced to 10 or 14 because our bodies just respond so slowly.
