Stomatognathic System
Functional & Anatomic relationship between teeth, jaws, temporomandibular joints, muscle of mastication and associated soft tissue.
The interaction between the nervous system and the stomatognathic system: from development to diseases
Development of masticatory system is based on functional needs in which jaw muscle function has significant effect on cranial morphology.

Mastication- process in which food is ground down by teeth- first step in digestion and increases surface area of foods to allow efficient breakdown by enzymes
The more we chew or gnaw- the more stem cells release- the more bone density we’ll enable- the younger we’ll look- the better we’ll breathe
Masseter Muscle
Chewing (Masseter) Muscle: located below the ears felt when you clamp your teeth- strongest muscle relative to body weight exerting up to 200 lbs of pressure on back teeth
(temporalis, lateral pterygoid, buccinator muscles)
Maxilla
Maxilla:: made of membrane bone that makes up canter of the face and is highly plastic- remodel and grow dense into later age by engaging the masseter- clamping down on the back molars over & over…
skull sutures
located throughout skull- spread a part throughout lifetime and allows bone to flex and expand from infancy to adulthood. Inside skull sutures body creates stem cells- precursor cells to all forms of tissue in our body and allow for new facial growth including the mouth
By 1500
Humans could spend their entire life eating nothing but processed foods in developed cities- food became more and more refined- advanced milling removed germ and bran from rice and flour- meats fruits, vegetables were being canned or bottled – methods extended shelf life of food and created unprecedented accessibility, but they also became mushy and soft
By Industrial Age- 1760
Dental Disease became rampant- increased incidence of crooked teeth and jaws was up tenfold- removing teeth became common practice to accommodate.
1800’s
Several scientists hypothesized that these problems were linked to deficiency in Vitamin D- without it bones in the face, airways or body would not develop.
Vitamin D helps the body resorb and maintain calcium and phosphorus critical to building bone
In 1930’s documented moderns industrialized societies with processed foods unanimously suffered obstructed airways, crooked teeth, more cavities, and poorer health
