According to me marpe seem to be straight garbage.
I’m wondering why mechanical expansion with tads are trendy.
I will give you the reasons from the research I’ve gathered as to why you shouldn’t do it both from an aeshetic and functional perspective.
-Assymetrical expansion.
Almost all human are too some degree assymetrical, the expansion device expands straight transversal and doesn’t take your assymetry in consideration. If you’ve done your fair amount of research you will see expansion totally demolish one’s aesthetic.
Marpe goes up to the nasal floor and indirectly affects your cheekbones when the midpalatal suture split occur.
If you have a cant that cant will exacerbate, your cheekbones separate assymetrical. No jaw surgery can correct that since the le fort 1 cut doesn’t go that high.
The main reason in my opinion as to why the mandible in people that’ve expanded assymetrical look skewed is because the tongue won’t be able to rest pararell in the mouth. Your mandible follows your tongue.
Assymetrical palate->assymetrical tongue position->assymetrical mandible.
All of this leads to tons of problem connected to the nervoussystem.
This whole sphere is in my opinion pseudoscience, orthodontist with basically zero knowledge of the body’s anatomy have started to claim that marpe is the best treatment for breathing problems. They all are at this moment following narratives and what I would like to call a quick fix to generate money.
The dental industry needed something “revolutionary” something to exploit to make their business profitable.
In recent years many are dissatisfied with their aesthetic and functional outcomes so marpe could redeem the bad reputation orthodontist in general had gotten(mainly because of extraction).
They take zero accountability for extraction-victims but now instead come with the solution of solving the breathing problem they and their philosophy by themself created. The lack of self awareness on them are ridiculous. Anyways.
- The human body is a 3-dimensional system.
Our craniofacial complex develops in three planes
•Transverse
•Horizontal
•Vertical
Altering only one plane(transverse) creates dimensional imbalances.
This will in the long run be counterproductive because I GUARANTEE YOU that the “bone expansion” in the loop of 5 years will relaps.
You need the mainly horizontal gain too for it to be stable, also a mobile tongue.
- Abnormal expansion of the palate.
There is nothing aesthetic or natural with 90% anterior expansion. Your whole palate gets deformed by getting that much of anterior expansion, also there are barley and alveolar bone remodelling at all since it’s just skeletal.
- Your ap(anterior-posterior) space decreases when dentist retract the incisors to close the gap.
I can rant about the importance of ap space for an eternity but no of the orthodontist/dentist seems to understand. Your arch length will decrease by the gap closing, when this happends your mandible are forced to be further back(since your ap space decrease and your mandible follows your tongue). This will make the breathing through the oropharynx worse.
This might also lead to scoliosis, ear ringings, headaches, unexplained depression etc etc.
AP space is litteraly the most important thing when it comes to breathing and AESHETICS.
- The harsh true is that once the sutures are fractured from the expansion and the beloved SKelEtaL expansion occurs, your maxilla will rotate in a clockwise rotation(see video).
From an aesthetic perspective this is just horrible. Your soft tissue drops, your orbit support decreases, your face are lengthen and your mandible move backwards(see image 2 what happends when clockwise occurs). There are several more hits on the aesthetics from the clockwise rotation but this post will be too long if I go into too much details.
- Arrogant people that follows narrative and hasn’t really got a good fundamental understanding of how the breathing works will say wider nasal cavity=easier to breathe through your nose.
Our body wants a small form of resistance, once the nasal resistance decrease after expansion the body create resistance further down the throat, affecting the oropharynx. I would like to call this placebo improvements, while it feels like the breathing is better after expansion(the reason why the hype from a functional perspective are so high) is because more air are coming through but it can’t get through as easy further down(oropharynx). The resistance basically changes position but since we are simple creatures we imagine that our breathing improves.
- Fracturing the sutures.
The only way to get this SKeleTal expansion is by fracturing the maxillary sutures.
That itself violates how craniofacial growth, neurology and tissue adaption works.
Suture are dynamic joints. They adapt gradually to light forces(marpe force~100-300 N, equivalent to 10-30 kg of force which is ridiculous much).
This fast expansion and fracturing tears sutural fibers apart instead of remodelling it. The gap is then by filled with scar tissues or irregular bone(BAD BAD BAD).
I know for a fact that some of you that’ve done expansion experience headaches, dizziness, tmj symptoms and autonomic dysregulation connected to the nervoussyetem.
Now I hate the clowns that always go by this “evidence based” in this expansion sphere. The “evidence” was in an extraction direction just 10 years ago(to this day a lot of orthodontist still doesn’t understand how extraction mess someone’s life up).
How hard is it to understand that everything regarding this is pseudoscience, nobody knows for sure what the best treatment are, the orthodontist follows the money and trend. Right now it is expansion, in 10-15 years the complain of many of the things I’ve named above will be overrepresent.
They don’t take accountability for anything.
- marpe-braces combination shrinks your skull and forhead, which will exacerbates baldness.
Now this theory is actually pretty interesting.
We do know that genetics and hairfollicles that are sensitive to DHT are the main cause to baldness.
The whole dental marketing about “straightening teeth” is so so paradoxal.
I haven’t got the energy to explain it all but basically braces makes your teeth straight at the cost of collapsing your face inwards(if you want all the mechanics behind regarding that you can send me a pm).
When the face collaps inwards muscles of the face and forehead must compensate for the loss of structural support.
What does it do? It creates chronic low-grade tension in the forehead region, altering blood flow and stressing hair follicles.
Instead of attributing hair thinning solely to DHT as is the mainstream explanation, it’s also about mechanical stress and vascular compromise from altered craniofacial structure that is a big cause(I’ve experienced it myself).
In other words, indirectly contribute to hair loss not because of hormones, but because of the way they reshape bone and create abnormal tension across the head.
One other explanation as to why people that are recessed in the mandible area or have had extraction-retraction and been forced to be recessed through decreased ap space are the superficial temporary artery(see image 3).
The superficial temporary artery are the main bloodprovider to the hair follicles. When your mandible are too far back either by just having a recessed mandible or the mandible are trapped because of lack of ap space the superficial temporary artery can’t provide enough blood to the hair follicles, they basically die and you lose hair.
