There are 22 bones in the human cranium. They make up what is commonly known as our skull. These bones join one another by way of joints called sutures. Upon close examination these sutures appear to look similar to jigsaw puzzle joints. These joints move, although only very slightly, and this cranial bone movement is necessary for what is called cranial rhythm. As we breathe, there is an inhale portion as well as exhale portion of our respiratory function. On the inhale half of the breathing cycle the base of the skull (known as the spheno-basilar symphasis) expands slightly, while the sacrum (the tail end) of the spinal column, contracts slightly. Then on the exhale half of the breathing cycle, the sacrum expands slightly, while the spheno-basilar symphasis contracts. Thus there is a pumping mechanism between the cranium and the sacrum that circulates the cerebro-spinal fluid around the central nervous system. This is necessary for good systemic health and normal functioning of our bodies. The same nutrients and the same toxins that have been found in the blood serum have also been found in the cerebro-spinal fluid. Thus it is necessary for this pumping mechanism to properly function in order for us to have good central nervous system health.
Two of the cranial bones that figure significantly in dentistry are the right and left maxillary bones which are joined down the midline of the roof of the mouth in what is referred to as the mid-palatal suture. These two bones make up what we refer to as the upper jaw. If someone loses a tooth in the upper front part of the mouth, dentists are taught to fabricate a bridge to replace the missing tooth. Unfortunately, this process ties the right maxilla and the left maxilla together and seriously disrupts cranial rhythm if the bridge happens to cross the mid-line, since a bridge is cemented into place, and thus cannot allow the individual right and left maxillary bones to move independently of each other. Since the two maxillary bones articulate with 72% of the other cranial bones in our skull, one’s cranial rhythm is significantly impaired. So you see, by the placement of a simple bridge to restore one’s appearance and chewing function, one’s systemic health can be significantly impaired. Thankfully there is a miniature cylinder and piston device that can be hidden in such a bridge that allows for normal cranial bone movement, if the dentist is aware of these facts and also knows where to find such a device. Also the existing bridge can be cut to free-up the maxillary bones and thus restore normal cranial function.
