Small and proper occlusal adjustment can make a big difference

The Seven-Stage Cascade

1. The head will begin to regress back to an upward and forward posture.
2. The forward head posture develops with the head tilting upward (flat occlusal plane tendency).
3. Vector of forces change — hypertonic digastric/suprahyoid muscles vs. physiologic vector of forces will ensue.
4. Alteration in the maxillary occlusal plane toward flat or level tendency relative to horizontal level.
5. Domino effect of masticatory muscles forces shifting the isotonic myo-trajectory back to one of pathology (posteriorly toward a habitual trajectory).
6. Compromised function of the neck moving from a lordotic curvature to a kyphotic curvature.
7. Dictation of abnormal jaw closure pattern (relapse of the neuromuscular myo-trajectory) occurs due to the proprioceptive engrammed occlusal forces of a distorted worn occlusal morphology will now take over and dominate the postural system.

This is what happens when the bite/occlusal management is not properly managed and or maintained!

Why the Occlusal Plane Is the Trigger

The maxillary occlusal plane is not a flat horizontal surface. It has a natural angled orientation relative to earth’s horizontal level. When a dentist flattens it — through occlusal equilibration that removes natural inclines, through restorative work that ignores the angle, through orthotic fabrication that misses the plane reference — the entire cascade above is being initiated, even when nothing else looks wrong clinically.

Most dentists never recognize this trigger because the occlusal plane error is not visually obvious in the mouth. The cascade does the revealing — weeks or months later, when the symptoms return and breaking crowns and restorations.

What the Cascade Actually Does to the Patient

Stage 1 and 2 are postural — the head physically moves back into the dysfunctional position the orthotic had just corrected.

Stages 3, 4, and 5 are muscular and structural — the muscle vectors revert, the maxillary plane reverts, the mandible drifts posteriorly back toward the old habitual trajectory.

Stage 6 is cervical — the neck loses its lordotic curve and moves into kyphotic compensation. This is where the patient feels it. Headaches. Neck pain. Shoulder tension. The “I thought I was better” recurrence.

Stage 7 is proprioceptive lock-in — the worn occlusal morphology now drives the system. The bite the patient escaped is the bite the patient is now living in again.

Why This Cannot Be Fixed by the Cervical Therapist Alone

Patients in relapse often return to their chiropractor, physical therapist, or massage therapist hoping to interrupt the cervical symptoms. The therapy provides temporary relief and then the symptoms return again. The cervical therapist is treating a downstream effect, not the upstream cause.

The cause is the bite that the dentist did not finish properly. Until the occlusion is micro-occlusally re-adjusted to the optimized myo-trajectory, the postural system has no structural reason to hold. The neck cannot stay aligned when the bite below it is telling the head to tilt up. The Atlas C1 and Axis C2 must be aligned and balanced by a skilled gentle chiropractor so the bite can maintain stability.

What the Dentist Must Do

To maintain an optimal physiologic (normalized) head posture over the vertebral spinal column it must be recognized that a proper mandibular occlusion must be micro-occlusally adjusted and positioned supported along an optimal myo-trajectory that is proven to be isotonic stable with effective alignment therapy in order to bring all the straining muscles including the neck and lower back and pelvis to a stable relationship.

Micro-occlusion is not optional in these cases. It is the entire treatment.  This is what GNM occlusion is about.

Frequently Asked Questions

🔹 My patient was doing well and now has come back with the same neck pain. What went wrong?

The patient is in cervical postural relapse. Something in the occlusion has shifted — most commonly a flattening of the maxillary occlusal plane through wear, restorative work, or incomplete equilibration. The 7-stage cascade above is the structural sequence the patient is experiencing. Resolution requires micro-occlusal re-adjustment on an objectively measured myo-trajectory, not more cervical therapy alone.

🔹 How is this different from a normal symptom flare-up?

A flare-up resolves with rest and minor adjustment. Cervical postural relapse follows a specific structural sequence — head reposturing, vector reversal, maxillary plane drift, mandibular trajectory reversal, cervical curvature loss. If the patient’s neck has moved from lordotic to kyphotic again, the cascade is already at Stage 6.

🔹 Why does this happen even when the patient is wearing the orthotic?

The orthotic supports the mandibular position the dentist established. If that position was built on a flattened or wrong maxillary occlusal plane reference, the orthotic is supporting the wrong endpoint. The masticatory and cervical muscle systems will continue compensating. The orthotic alone cannot override an occlusal plane error.

🔹 Can the dentist prevent this in the first place?

Yes — by understanding the maxillary occlusal plane is angled, not flat. By using the Fox Plane technique rather than the classic HIP mounting in Phase II restorative cases. By recognizing micro-occlusal interferences before they propagate through the postural chain. Prevention is a function of training.
