Can adult undergo expansion?

Can adult undergo expansion?

Robert Mason responds:
Yes, adults can be expanded — but — the expansion is primarily the result of tipping the crowns of the teeth labially or buccally, rather than the bodily movement of teeth that occurs under age 16 when the midpalatal suture is cartilaginous. After age 16, the midsagittal suture is totally ossified (turned into bone) whereas previously it was a cartilaginous band traversing the length of the hard palate. . For adult expansion, longer periods of retention are needed to maintain the expansion.
One of the problems with expanding out adults is that, if held/retained for many months out of fear of relapse, the roots of upper molars can poke through the buccal bone that contains them. When a root pops through the alveolar bone, it is called a fenestration, and this is an unspoken problem among those orthodontists who claim that they can expand everyone out and never need to extract. Causing fenestrations is one of many complications from this rigid and inappropriate view that everyone should be expanded and no one should undergo extractions. You can only expand individuals out so far, and relapse in many non-extraction cases is greater than had extractions been done appropriately.
For expansion in children, the cartilaginous suture area widens and then bone eventually fills in following the expansion to maintain the width created. ~ Bob
 

Hypothyroidism

at times her tongue was in and her lisp were together (which suggests to me that there are no nasal breathing issues). Her tonsils were not visible (small???). She seemed to easily be able to breathe through her nose. Parents report that she does snore a little. Her cheeks were pretty “puffy” looking, but she is a young child so it seemed like it could be just a baby face. On the inside of her mouth, her cheeks seemed really “thick”.


 

It is fair to start patients when I will be leaving in 3-6 months.

“Because you know Phase One, most especially proficiency exam #1, you can build a decent foundation for a patient and then, even if they move or you move, they have the most important basic skills.


 

When apraxia rules all… it explains many of the OM symptoms we see

Hi Sandra, So glad that you were able to meet with my patient. I have been perplexed about him. His OM issues seem to be compounded by his difficulty with nasal breathing (polyps), poor motor planning, and weak sensation around his lips and tongue. For sure…at the very least! My basic results from exam: 1. […]


 

8-year old girl with a pretty severe tongue thrust and speech errors on all the sibilants plus /r/.

I recommended a lingual frenectomy, which was done last week. She is coming back to therapy Wednesday, and I was wondering if there are specific exercises that should be done post-frenectomy to avoid scar tissue from forming.

A nice “flow” of conversation will help to embed that “h” sound within words and phrases rather than just saying it at the beginning.

Metal rake type appliance being bent over by tongue

I’ve got her oral habits “fixed” for during the daytime. However, the nighttime is creating a pretty big problem and I’ve racked my brain…


 

Frenum Question- R: Techniques and Interventions to Correct /r/

Sometimes a frenum is not short but is still restrictive because of the attachment location on the tongue or onto the lower alveolar ridge.


 

Decreased Lingual Movement

He presents with decreased lingual movement but does not have an obvious anterior tongue tie. He is unable to stick out his tongue without it resting on his teeth and he cannot click his tongue without moving also moving his jaw. I am really at a loss for how to help him.
