MODIFIED CHEWING The jaw elevator muscles develop the main forces used in mastication. The force generated during routine mastication of food such as carrots or meat is about 70 to 150 newtons (16 to 34 lbf). The maximum masticatory force in some people may reach up to 500 to 700 newtons (110 to 160 lbf). Being consistent we can train to be able chew 5+ pieces of hard gum Falim® and build up the strength of our masseters from constant chewing, it is not unreasonable to expect to be able to exert 350+ Newtons of force per mastication. To compare how significant this is maxilla protraction is generally done with 10 Newtons, and the tongue can exert around 5 while hard mewing, so it is safe to say that chewing is 60x more force than your tongue, making it an extremely potent change for actual bone change, many people when thinking of chewing only look at it as a way to build masseters, but this is simply a bonus. Daily spurts of cyclic load caused sutural strain throughout the skull. The regime likely enhances suture growth and may be therapeutically useful. This means that sutural growth is possible from forces that only take place for few minutes a day, and sutural growth is essentially what you need to make change in bone, past age 12 the sutures begin mature (and while they don’t fuse till very late in life, they become very hard to stimulate growth from), chewing opens up an opportunity with the insanely high forces as a gateway to awaken these dormant sutures. While that should have provided some helpful background info on chewing, this is part of the thread that will help you actually change your bone, based on your method(s) of chewing, you can get any of the following assuming you follow the proper protocol: Decreased midface length (or increase if your midface is overly compact) Increasing orbitals more compact Making cheekbones higherset Increasing forward growth (maximizing really) Can make your sutures more responsive to generating new growth Remodels the jawbone itsself to be more robust There is also the possibility of increasing the length of your maxilla laterally, some studies also talk about the association of masseter muscles and maxillary transverse width. The chewing exercises and their function in question: Decreasing midface length- chew with the incisors Increasing midface length- chew with back molars Making cheekbones higherset- chew with first molar to first premolar Making orbitals more compact- chew with first molar to first premolar and incisors Maximizing forward growth- chew with the incisors Weakening sutures for moving the maxilla forward (will give much quicker mewing/facepulling results)- chew with incisors Remodelling mandible to be more robust- any chewing method will give this change You can combine methods as long as they dont contradict each other, incisor chewing vs back molar chewing, personally i will be chewing falim for one hour on incisors and one hour on my molar-premolar for an hour as well. Mechanisms: Chewing on your incisors will apply an upward force to the anterior part of the maxilla inducing a CCW(counter clockwise rotation) rotation, while inversely molar chewing will cause a CW maxilla rotation, CCW rotation will also move the orbitals upwards The upper/middle part of the maxilla are located relatively at around the center of the maxilla (the center of resistance is here as well), meaning that for a upwards translation of the cheekbones you need to chew with the teeth located in the middle part of the maxilla, as tipping the ends will not influence the center, this is the same mechanism that pertains to the orbitals becoming more compact, as the maxilla translates upward, so do the orbitals and zygos which will lead to highset zygos + more compact orbitals Since when developing we are lacking the support of the tongue which would cause us to grow vetically instead of forward, we all have a bit of CW rotation built into us, when there is CW rotation it lessens forward growth, by correcting it you will gain forward growth as well, it is similar to gaining height from fixing posture, you aren't actually growing, just maximizing what you have.
