The Cranial Influences

There are twenty two cranial bones (excluding the six ear ossicles) which function as a synchonized unit. A distortion to one affects the entire unit. The cranial dura is part of the dural tube which extends through the foramen magnum, attaches to the upper three cervical vertebrae and continues down to the second sacral tubercle where it attaches. Subluxations or fixations anywhere along its path will affect cranial motion. In addition, there are 136 muscles in the head and neck area. Muscle tension or spasm will influence cranial motion. Dental malocclusions in the form of hyper occlusion, deep overbite, crossbite (anterior or posterior), a narrow maxillary arch, faulty crowns or high cant of the maxillae on one side will all have influences on cranial motion.

Migraine Headaches

Migraine headaches usually affect one-half of the victim's head. Since the dural tube is a reciprocating membrane, tension or torquing in the skull will cause one side to be in traction while the other side provides the slack. The nerves passing through the tensioned side will be responsible for the varied and extensive pains. The dural torquing can result from a single or various combinations of structural distortion involving the pelvis, spinal vertebrae, dental malocclusion or cranial bone restrictions. These structural problems can be triggered by emotional, physical, nutritional or physiological stressors (e.g. organ dysfunction, under-active thyroid, muscle spasm or weakness, fixed and removable dental bridgework)

  Dear Farid,

The term Craniodontics has been coined by Dr Gerald Smith to focus attention on the fact that use of dental orthopedics/orthodontics or any restorative dental procedure that directly changes the occlusion will affect the alignment of the 22 cranial bones (excluding the 6 ear ossicles). The effectiveness of dental orthopedics in expanding the maxillae both transversely and sagittaly is well documented, however the time has come when dental practitioners must look beyond the parameters of the teeth and alveolar bone to the highly functional cranial system.


  • Dural Tube

    The dural tube is a continuous membrane that surrounds the brain, passes out of the base of the skull, attaches to the first three cervical vertebrae, and continues down the spinal cord where it finally attaches to the sacrum. This tube is the source for structural disturbances being transmitted from one part of the body to another. Because the body works reciprocally, imbalances in the skull can influence the neck, lower back, and pelvis and the reverse is also true. This dural tube provides a functional link in the entire system. Any movement, however minute, in one part of the system has a compensatory effect in other parts. To give you an example of this intimate connection, a baby that was delivered by forceps could have cranial distortion resulting in lower back pain at the level of sacro-iliac joint (SI joint) later in life.

  • The cranial dural membranes

    The cranial dural membranes act as stabilizers to the vault bones. Physical trauma (whiplash injuries, blows to the head, forceful tooth extraction, etc.) and dental malocclusions have the potential to disrupt dural membrane balance and normal cranial rhythm. Such changes can cause adverse neurological function throughout the body.

  • The Maxilla

    The upper teeth are set in the maxilla. The maxilla is not just a jaw, it represents the front third of the cranial base. If the upper jaw is distorted (crooked teeth, crossed bite, one side higher than the other, canted maxilla, etc.), then the forces generated by the unmatched biting teeth can distort the skull. To make things even more complicated, in the head and neck region there are 136 muscles. Muscle tension or spasm can influence cranial motion. Among these muscles are the muscles of mastication (chewing). Since these muscles are all attached to the skull, improper bite can often trigger muscle spasms, which in turn can jam the sutures and distort the cranial bones. As if this were not enough, patients with a deep overbite, underdeveloped lower jaw, cross bite, or collapsed bite may experience cranial distortion and dural torque. Many of them suffer from headaches, migraines, neck and shoulder stiffness and lower back pain. Some may have itchiness or stuffiness in the ears and many have clicking jaw joints.
