The Scientific Reason Why Doctors Feel a "Reverse Direction" Cranial Movement During MCB Splint Treatment

In clinical MCB (Mandibular Cranial Balancing) settings, an interesting observation often comes up:

"The doctor placed the splint and could precisely feel my cranial bones moving in the opposite direction of their original torsion."

Is this just a subjective impression, or is there real science behind it?

Recent research on the CranioSacral Rhythm (CSR) provides a clear scientific basis for this phenomenon.

1. A 59-Micrometer Motion – Tiny, Yet Palpable

In a 2021 study, Rasmussen and his team used highly sensitive instruments to directly measure the rhythmic motions of the human head. The average amplitude of this motion was approximately 58–59 micrometers (μm) .

Importantly, the study concluded:

"This level of subtle motion can be reliably detected through skilled palpation."

This means that an experienced clinician—with decades of hands-on training—can indeed perceive micro-rotations and side-bending changes in the cranial bones. It is not imagination; it is a measurable physiological event.

2. Why Does It Move in the "Opposite Direction"?

This phenomenon is best explained by the modern Pacemaker Theory of craniosacral physiology.

The brainstem contains specialized networks of neurons that act as biological pacemakers, generating rhythmic electrical impulses independent of heartbeat and respiration.

These impulses drive neurogenic vasomotion—the rhythmic contraction and relaxation of blood vessel walls—which in turn produces subtle, rhythmic movements of the cranial bones via the dural membranes and connective tissues.

When an MCB splint corrects a misaligned jaw, it removes abnormal tension and strain that had been affecting the brainstem and its pacemaker activity.

As the nervous system restores its natural balance, the cranial bones begin to return toward their normal, neutral alignment. This creates a palpable movement that is opposite to the direction of the pre-existing torsion, side-bending, or rotation.

Thus, the "reverse direction" felt by the doctor is not a mechanical push, but rather a neurologically driven restorative motion.

3. From Pressurestat to Pacemaker – The Scientific Evolution

Earlier models (such as Dr. Upledger's Pressurestat Model) attributed cranial motion primarily to cerebrospinal fluid pressure fluctuations.

However, modern neuroscience has advanced our understanding. The current Pacemaker Theory proposes that:

"The CranioSacral Rhythm arises from intrinsic brainstem pacemakers, and the motion is an expression of neurogenic vasomotion—not merely a passive fluid phenomenon."

This evolution aligns clinical observation with cutting-edge neurophysiology.

Conclusion

The "opposite-direction cranial movement" perceived by experienced practitioners during MCB splint therapy is:

Scientifically measurable (approx. 59 μm),

Physiologically grounded (brainstem pacemakers + neurogenic vasomotion),

Clinically observable through skilled palpation.

It represents the body's innate ability to self-correct and restore neurological balance—a fascinating bridge between clinical art and modern science.

(Mandibular Cranial Balancing – Precision Medicine Through the Jaw)

Most people think of the jaw simply as a chewing tool.

But MCB therapy uses the microscopic position of the jaw to restore cranial motion and release deep-seated tension in the nervous system.

Although the skull appears rigid, it actually undergoes extremely subtle rhythmic motion (flexion & extension) – like a quiet, internal breath.

However, due to past trauma, falls, or long-standing postural habits, the cranium's subtle rhythm and the surrounding dura mater (the membrane enveloping the brain and spinal cord) can become twisted.

This dural torsion creates tension at the cranial base, which in turn pulls on the jaw joint (TMJ) and creates a tiny "empty space" (gap) where the upper and lower teeth don't fully meet.

Here is the key clinical insight:

The TMJ misalignment is not the root cause. It is merely a physical symptom of the deeper cranial distortion.

In MCB therapy, we use the jaw simply as a precise tool – a mechanical access point – to gently unlock the misaligned skull and release the twisted dura mater.

By correcting this gap, we restore the skull's natural rhythm, which subsequently reduces excessive tension in the neck muscles, alleviating issues like torticollis (cervical dystonia), chronic headaches, and shoulder pain.

Step 1: Listening to the Cranial Breath

The therapist gently palpates the patient's skull to sense its subtle rhythmic motion.

Then, ultra-thin measuring shims (less than 0.1mm thick) are placed between the molars, one by one, until the cranial motion returns to its fullest, most natural state.

There is no fixed number of shims – each patient is unique. The therapist stops only when the skull "breathes" freely again.

Step 2: The "Onion-Peeling" Healing Response

Filling the gap releases tension in the dura mater.

This membrane stores a chronological record of physical trauma.

Remarkably, as treatment progresses, symptoms often reverse in time:

Recent neck pain resolves first,

Then older shoulder stiffness from years ago may briefly reappear and fade,

Even postural patterns from childhood can surface and dissolve.

This step-by-step, layer-by-layer resolution is called "peeling the onion" – a phenomenon rarely seen in other jaw-based therapies.

Step 3: Custom-Made Device Fabrication

Once the optimal 3D jaw position (height, forward/backward, and side-to-side) is identified – a position that brings the cranium into its most balanced rhythm – a personalized splint is crafted for that patient.

This position is unique to each individual. It is their physiological neutral point, where the cranial base and dura mater are most relaxed.

Manual cranial therapies (such as osteopathy) are valuable, but even the best practitioner can only treat a patient for about an hour.

MCB, however, works the moment the device is placed – and the therapist continuously reads the patient's cranial response, refining the 3D position in real time.

The device is not a static "gadget"; it is a living, adaptive tool that evolves with the patient's nervous system throughout each session. The jaw serves as the precise lever to correct the skull, not the other way around.

MCB therapy recognizes that the real issue lies in the twisted cranium and dura mater. The TMJ is simply a precise tool to unlock that torsion, restore the skull's natural rhythm, and guide the nervous system back to balance – layer by layer, patient by patient.

MCB Splint.

Once dentists gain sufficient experience and become skilled after attending the MCB Splint Seminar, patients in each country will no longer need to travel to Korea for MCB treatment.

I am sharing the treatment experience of Esmir Hidic, who visited from Canada for MCB therapy. The following is the change he described after 45 treatment sessions. The before-and-after photos were taken after 128 MCB treatments over 9 days, during which the treatment effect of the previous MCB/H changed from 10 minutes to 1 hour.

MCB treatment – My review after 45 sessions completed

The MCB treatment is definitely working, it’s faster and more effective than I thought!

After only 45 sessions, I was able to notice the following changes:

1- Both my jaws (maxilla and mandible) rotated forward. I can finally notice my jaw

line, angles are getting better, fuller jaws when they sit at the right position. I

didn’t think I would see such changes with only 45 sessions.

2- My occlusion has gotten better, just by changing the position of the jaws. The

teeth seem to adapt along the way.

3- My whole body is unfolding, untwisting and look more natural, just like it’s meant

to look after birth. Good proportions and alignment at the facial level, shoulders,

hips, knees and ankles.

4- My breathing unclogged through my nose by the realignment of the sphenoid

bone.

5- My neck pain at C1, C2, C3 level also improved, not at 100% yet, but it will

eventually.

6- My right hip pain is getting better too. Not 100% back to normal, but that will

take more time and more sessions as it’s deeply jammed.

7- My facial pains stopped for the most part.

8- Mentally, I have less brain fog now, I’m more joyful and stable. I became more at

peace with myself and less stressed. I can finally complete tasks that requires

significant mental effort.

9- The tension and stiffness in my overall body have decreased, especially in my

arms. I can now use my hands better to grab things and I don’t have as many

cramps in my fingers as before.

10- My skin became more soft, less dry, less dandruff, etc. More tolerance to sunlight.

Overall, everything is improving well. I’m looking forward for my 80 sessions remaining!

Hopefully that will be enough to achieve 100% of my goals and enjoy a pain-free life as before

TMJ Treatment and Change:

When will we be ready to embrace it?

Temporomandibular joint (TMJ) treatment has had many proposed methods over time, but there does not yet seem to be a method that has definitively proven effective for the whole body.

Not long ago, a practicing physician from Prague visited my clinic during orthodontic bracket treatment. She was diagnosed with facial asymmetry and body misalignment, and experienced MCB splint therapy. She was aware that bodily misalignment is related to asymmetry in the facial bones.

Yesterday, a person from Canada came in; this individual had undergone extraction orthodontics and whom I had consulted with online three years ago.

There are many around the world—including in Korea—who claim not only to treat TMJ or craniofacial structures, but to treat systemic disorders. Most of them use applied kinesiology for diagnosis and treatment. I myself served for five years as a dental director in a Korean applied kinesiology organization. It is a good discipline. Yet many people—including in Korea—have not gone beyond the level of using applied kinesiology. For example, in the case of the TMJ: applied kinesiology can determine which side of the joint is problematic, and can evaluate how effective a TMJ device is. However, it cannot reveal the direction of asymmetry between the right and left TMJs, or the detailed joint motion. The way to know those is through osteopathic medicine. In Korea, there is almost no practice of osteopathy. 99% of the population do not know the word “osteopath,” and few have experienced osteopathic treatment. It takes a long time to understand the motility of the TMJ.

I have devoted my life to performing orthodontic treatment for people with TMJ problems. Even in the United States, where osteopathy was born and has developed, it seems that almost no one applies the concept of osteopathy when fabricating splints for the TMJ.

Dentistry still remains dominated by the concept of CR (Centric Relation). Many osteopathic physicians have long claimed that the temporal bones move, and treat on that basis, yet the mainstream thinking has not changed. Many dentists still believe that if the mandible (lower jaw) is asymmetric or if the lengths on the right and left differ, surgery is required, and they in fact treat by surgery.

When will this way of thinking about the TMJ change?

Dentists around the world must recognize that treating patients based on the conventional habitual jaw position can significantly impact their lives.

One key consequence is reduced blood circulation in the cranial region. This effect can be felt by anyone.

First, palpate the arterial pulse around the eyebrows while the teeth are not in contact. Then, close the teeth together and observe the change in pulse. If the pulse weakens or disappears when the teeth are in contact, it means lifelong reduced blood circulation to the brain.

On the other hand, when the mandible is positioned in the MCB position, a strong pulse can clearly be felt.

Dentists, when your patients discover this fact, how will you take responsibility? You cannot simply claim ignorance to escape accountability.
