Your Spine & TMJ Treatment

Dr. Chapman painlessly re-positions a patient's atlas using AO Transdermal Atlas Positioning Technology

An optimally balanced body starts with:
                     a balanced head and neck...
                                            then a balanced jaw......,,
                                                                         then a balanced bite..

The procedure is performed by programming the instrument with the correction vector, and the instrument is placed on the neck just below the ear against the skin targeting the transverse process of the atlas.

The doctor activates the electromagnetic magnetic driver, which produces 1.6 pounds of kinetic force. The kinetic wave is transferred through the fixed stylus of the instrument into the tissue surrounding the atlas vertebra. The directional wave interacts with the surrounding tissue and  transverse process of the atlas causing this structure to transfer the energy to the adjacent axis vertebrae and cranial base. The capsular joints are mechanically and neurologically stimulated and reset. The TAP procedure essentially "reboots" the  cervical/mandibular neuromuscular complex. 3-D post imaging is then performed, and a measurable reduction in atlas displacement often results from this initial procedure, thereby reducing the atlas subluxation.

The force is gentle, and very specific as to amplitude, duration and direction. The effect is a correction of the functional pivot point of the not only the head and neck, but the jaw as well.

Following the procedure, the patient is physically re-examined, and, if found improved, post-imaging and other objective studies are performed to map out and quantify changes in the position of the head, neck and mandible. If a balanced alignment (orthogonality) has been achieved, then the procedure is complete.

Transdermal Atlas Positioning is best performed using the Atlas Orthogonal (AO) Adjusting Instrument designed by Dr. Matthew and Roy Sweat. Unlike hand adjusting, the AO instrument is designed to perform the TAP procedure with maximal precision and minimal error.

The TAP procedure is a corrective cervical spinal alignment procedure performed by Board Certified Atlas Orthogonal chiropractic physicians. The non-surgical procedure  includes the use of 3-dimensional digital images, either from Cone Beam CT or X-radiation to identify and precisely locate malpositions of the skull, the atlas and the axis, as well as the 5 other cervical vertebraes. A biomechanical analysis is performed and a correction vector is derived.

The Odontoid process
It is logical and simple. When the axis of movement of the jaw is askew, the angular movement of the jaw (which moves around the skewed axis) also becomes irregular and skewed in its movement.  Consequently, a large component of treating the irregularity of the jaw joints in their motion often starts and finishes with correctly positioning the occipital-atlantal-axial joint. This is accomplished through image guided Transdermal Atlas Positioning (TAP) of the of the Atlas bone.

The simple and identifiable functional axis of movement for the jaw is a very important structure in cervical spine, namely, the odontoid process of the C2 vertebrae, also known as the dens.   The name “dens” provides an important clue. In Latin, dens means “tooth”.  Thus, the functional axis of  jaw movement is located in the upper cervical spine.   Wonders never cease! This dynamic pivot point of occlusion, takes place around the only part of the human spine dubbed the “Tooth”, by anatomists of old--and ironically, it is located in the spine.   The dens is recognized as being a key anatomical structure in the proper alignment of the head on the neck and plays a prominent role in the condition known as the Atlas Subluxation Complex. 

TMD Syndrome may occur when an imbalance of the jaw joint occurs. This occurs when the normal functional “positions” of the jaw joints shift into irregular positions during movement and use, causing uneven “grinding” or “wearing” use-patterns.

This abnormal use-pattern and jaw behavior can cause  a significant amount of pain, inflammation and tooth wear, making chewing, sleeping, speaking and even sleep-breathing difficult. 

The pain and problems of TMD can be quite diverse. Jaw disorders can refer pain into the head, neck and upper back, especially the face and the teeth and can cause severe dizziness.  The jaw or mandible is operated and positioned by 68 pairs of muscles. As mentioned above, these muscles attach to the head, neck, back and shoulder structures. The jaw joint is not a hinge joint like the elbow. It is very complex in its form and function. It helps to perceive the jaw as being suspended and “docked” in its’ joint space (glenoid fossa) much the way a boat is docked in a slip while tethered there. While in action, the jaw joint varies widely in functional movement; moving up and down, backward  and forward and slightly side to side.

Transdermal Atlas Positioning Procedure:

(TAPP) such as Atlas Orthogonal can effectively reduce Atlas Subluxation and re-position the Mandible. Essentially, getting one’s head on straight can make all the difference.    

TMD is also known as TMJ Syndrome. When the behavior of the jaw becomes irregular, we may experience pain, dizziness and discomfort. This is an indication of underlying joint disease process or pathology.

The Atlas Orthogonal (AO) procedure as seen to the right can restore the essential balance and positioning of the head, jaw and neck. This procedure in turn signals the entire body to decompensate and return to a more ideal vertical position. This is important from the  perspective of TMJ treatment, as malpositions of the head, neck and shoulders can complicate TMJ Syndrome.  When the head is "off-centered" on the top neck bone called the atlas, it carries the jaw with it into a stressed and strained position. This stressed position affects the jaw directly and can cause the jaw to develop irregular use patterns which can stress and cause excessive wear on the jaw joints causing extreme pain.
