arch. A wide arch promotes a wide, open airway and room for all teeth
“Living bone is extremely susceptible to the guidance and influence of pressure and stimuli.” (Klein, 1951)
consider the fact that (self-ligating) braces use very light forces to move teeth over time, in much the same way the tongue can exert light forces on the maxilla if proper posture is adopted and remodel the facial bones overtime…
Bone is living tissue that can adjust to changing mechanical needs
“The skeleton is a metabolically active organ that undergoes continuous remodeling throughout life. Bone remodeling involves the removal of mineralized bone by osteoclasts followed by the formation of bone matrix through the osteoblasts that subsequently become mineralized. The remodeling cycle consists of three consecutive phases: resorption, during which osteoclasts digest old bone; reversal, when mononuclear cells appear on the bone surface; and formation, when osteoblasts lay down new bone until the resorbed bone is completely replaced. Bone remodeling serves to adjust bone architecture to meet changing mechanical needs and it helps to repair microdamages in bone matrix preventing the accumulation of old bone.” –http://www.ncbi.nlm.nih.gov/pubmed/17308163
“Muscles trump bone and teeth. Airway trumps everything!
Pressure on the forehead from the papoose board above helped these indigenous people form what they considered a beautifully shaped forehead. Likewise, consistent muscle pressure surrounding the jaws helps shape faces to their maximum potential over a lifetime – or not. Oral/facial posture – correct or incorrect, guides facial growth. Early influences of good oral posture, before growth slows significantly at about age twelve, provide the maximum benefits of a lifetime of better breathing, chewing, swallowing and sleeping.”

Video on the Process of Bone Remodeling
“it is also believed osteocytes form a complex network in bone that can sense any increased workload on the bone and respond by triggering the differentiation and activity of osteoblasts to increase bone density. Conversely when bone experiences reduced loading conditions such as during long term bed rest, absorption and remodeling increase to eliminate underloaded bone.”
Facial Beauty and the Maxilla
“The maxilla is one of the crucial elements in facial beauty. Anatomically it provides the support for the mid-face and if it is forward then the patient will have ‘good bone structure’ and attractive eyes1. If it is back they will be flat faced and appear to have a large nose. The eye is especially vulnerable and if the maxilla is down or back, the outer canthous of the eye will drop. This can easily be recognised because it will give the patient a sleepy look and some of the white sclera of the eye may be visible below the iris. This always looks unattractive and is a reliable sign of severe maxillary retrusion.”
“The work of Proffit and his colleagues9 (2000) would suggest that if the teeth are in contact for more than four hours each day they will intrude or if out of contact for more than eight hours each day they will erupt. Clearly these figures will vary between individuals but the height of everyone’s occlusion must depend on a combination of the force and the period of time that the teeth are in contact. The work of Kiliaridis and Kalebo10 has shown that strong muscles of mastication can encourage horizontal growth in both forward and lateral dimensions. This would suggest that we should encourage our patients to keep their mouths closed, eat hard foods and perhaps chew hard gum.“-http://www.tmj.ro/article.php?art=524124766124496
Treating the Cause Not the Symptoms, By training kids proper tongue posture, may reduce Orthodontics obsolete?
New treatment method for kids and adults to straighten teeth without braces.
It is simply a mouth piece worn at night that prevents mouth breathing so the patient learns to keep mouth closed during sleep.(it has a mouth guard that blocks air from going through the mouth so the kid will learn to breathe through nose) Also has a tag for where the tip of tongue should be. And bumper for lips to prevent lip activity during swallowing.
The goals of Myobrace system:
- Correct nasal breathing Lips together at rest.
- Correct tongue position.
- No lip activity when swallowing.
- Good facial development
- No braces, retainers, or extractions (if possible)
- Straight teeth
Kids & Adults are getting changes and straightening teeth just by training the tongue and to make it a habit to keep mouth closed during rest and sleep.
Orthotropics does the same thing, biobloc has fangs that come out that hits the bottom palate whenever the kid tries to open their mouth, which makes it very uncomfortable to open the mouth. So the kid learns subconsciously over time to keep their mouths closed. This becomes the new habit & proper posture pattern is established, and with closed mouth, the tongue has very good chances of naturally rising up and resting on the top palate.
By retraining the closed mouth and tongue on upper palate posture with proper swallowing pattern, over time the maxilla comes forward and you get the drastic positive changes you see from many before & afters of biobloc treatment cases.
It is the force of the correct muscles of tongue working in concert with cheeks, lips, and jaw muscles and also just as important is which incorrect muscles aren’t being used that will begin to remodel the whole face.
This mouth piece either myobrace or biobloc is a great strategy for kids who are not all that invested in correcting their postures, these appliances force them to change, & to create new positive habits, and once it becomes habit the appliance can come off and the kid will still retain proper facial form throughout life. Since the properly functioning muscles becomes the lifetime retainer.
If you are an adult and you have great needs/desire to correct this, then you may find that you are habitually trying to correct these habits all the time and overtime you notice that you are naturally keeping your mouth shut or your tongue is naturally rising and resting on the roof of mouth. You may find that these appliance aren’t necessary. Remember that oral myofunctional therapists accomplish the same facial changes for the better without the use of these appliances. However this does take some dedication & effort from the patient.
Once you begin to notice positive habits are becoming your new norm, then you will most likely begin seeing seeing subtle positive changes taking place in the face if you have not seen them already.
What I have noticed, really aids in this process of adopting the habit of keeping mouth shut, teeth together, and tongue on roof of mouth is to strengthen jaw muscles by increasing masticating effort throughout the day, increase lip closure strength with something like Patakara lip trainer, and working your tongue throughout day to continuously remember to keep that tongue raised to the roof of mouth.
To train proper swallowing it is best to practice with meals, but often times I forget to be conscious of proper swallowing during meals let alone pay attention to how I’m swallowing normally, however just whenever I can remember to practice it and to do proper swallowing randomly throughout day when you take sips of water or what I have been doing is to just practice with saliva.
During a proper swallow, The teeth should come together and the tongue should naturally rise to the roof of mouth to create a seal. As the swallowing pattern commences the tongue automatically should press against the roof of mouth and spread / flatten out towards the arch of the upper teeth. I presume this force has a lot to do with creating wide dental arches in people that never needed orthodontics because they were swallowing properly.
What I noticed was that for a while it was uncomfortable or felt unnatural to swallowing with teeth together. This tells me I was swallowing with teeth apart most of the time, this is the suckle way of swallowing where the cheeks or lips are used to create the negative pressure to suckle food down, or suck food down. With Teeth apart the cheeks and lips have to squeeze inward to create the suction for the swallow, this is said to be one of main causes of narrow palate and dental crowding.
In a proper swallow there should be no visible activity in the lips or cheeks from outside view. Basically no one should be able to tell that you swallowed.
Dr. Mew estimates 85% of people are still carrying some form of infantile suckle way of swallowing. Pretty high numbers and just from what I can try best to observe in myself I wouldn’t be surprised if I was one of them.
With strengthening of jaw muscles, I am noticing my teeth are in contact with each other through day more often then before. And teeth are more likely to come in contact when swallowing as well which aids in developing the proper swallow. Along with strengthening lip muscles, I feel has tremendously helped my ability to keep lip sealed throughout the day. Whereas before I felt my lips would unconsciously fall open slightly during the day, or especially when I drift off into sleep, Since I have been extra sensitive in these things I would be conscious enough to feel this occurring. Or when coming back to consciousness from sleep I notice that my mouth had flung open during sleep. Before my lips felt sort of flabby (best way I can describe way) after lip training, my lip feels more firm and the upper lip and bottom lip meeting together to create the lip seal feels more secure and stronger.
(It is this proper lip seal that keeps teeth straight and aligned, preventing teeth from tipping forward. Keeps everything nicely in, it is like nature’s natural braces…in my opinion, you can visualize how the tongue and lips can form the dental arch naturally if they are in position)
Before training these facial muscles I was noticing my mouth falling open during sleep however by training jaw muscles and lip strength I am starting to notice to opposite, that my mouth is closed, teeth touching when coming back awake. It is interesting to observe these changes. However it is hard say at this point if I have for sure completely fixed these habits, unless I tape a video of myself during sleep lol, best I can do is to keep training my muscles. And I used to use tape to keep lip closed during sleep but this was before I learned about importance of muscles and before I was training lip and jaw muscles. Tape may be a decent temporary solution for you, however once I started strengthening the mouth closing muscles I felt I no longer needed the tape.
Some of the evidences that people notice of mouth closed during sleep is more restful sleep and less tossing in bed, and no more snoring. If you sleep with your significant another they should be able to tell you right away something changed by the increase in their quality of sleep due to the fact you are no longer snoring lol but since I am single no for sure way to tell lol. However I do recall that I used to wake up to drool marks on pillow. I never see that anymore…which is like my for sure way of finding out that my posture during sleep is changing. Also my mouth feels perfectly normal and moist upon waking…but I can’t remember if I had dry mouth before? I think maybe because I tend to drink water right away upon waking? also I think I notice I am tossing less in bed and my quality of sleep seemed to be better these days, although these aren’t night and day changes, it may be that changes are happening gradually that I’m just not aware of the differences.
That Jaw Muscle though is important and this is only my most recent findings, I’ve been training jaw muscles maybe 2 weeks. Dr. Mike Mew said that sleeping on his back was his favorite position but there’s many teachers and doctors out there who advise against that because that’s the position that the mouth is most prone to falling open during sleep and the tongue falling back into the airway causing snoring and sleep apnea. But Dr. Mike Mew says he experiences none of those things because he has good “muscle tone” which basically means he has good jaw muscle strength because he chews his food thoroughly and does a bit more chewing than the average person eating soft modern diet.
