MCB position Mandible !!

In the MCB position, the mandible and cranium (temporal/occipital) are set at a balance point; each tooth contact drives PDL/TMJ/masticatory feedback that re-balances muscle tone toward the opposite of the prior torsion, so the mandible closes along a least-strain path and the face/body de-twist over time—your mandible behaves like a built-in splint.

** Mechanism (neurophysiology)

1. Sensors: PDL Ruffini endings, TMJ mechanoreceptors, and muscle spindles sense contact patterns.

2. Central integration: Trigeminal nuclei–reticular formation–cerebellum adjust motor output within 50–200 ms.

3. Muscle rebalance: Removal of deflective contacts reduces over-tight muscles and activates the contralateral side; joint spaces become more even.

4. New closure path: Repeated contacts create a learned MCB closure (central pattern).

5. Postural chain: Hyoid–cervical–shoulder linkage transmits changes to head/neck/body alignment.

** Osteopathic view

BLT concept: when ligamentous/fascial systems find a balanced tension point, mobility returns; reducing cranial torsions (temporal/parietal, SBS patterns) via occlusal input allows the system to unwind opposite the original twist.

** How it differs from habitual-bite orthodontics

1. Conventional: align teeth within the current neuromuscular position.

2. MCB-concept: establish a balanced mandibular–cranial position first, then move teeth to preserve and reinforce that balance.

!!! Seeking collaborators for MCB position research

We plan a prospective, randomized crossover study testing brain, autonomic, airway, posture, and occlusal-mechanics changes with the mandible set in the MCB position, using objective endpoints (T-Scan, sEMG, HRV, PSG, CBCT, posturography, fNIRS).

We welcome university and hospital teams in Orthodontics/Oral Physiology/TMD, Sleep Medicine, Rehabilitation/Biomechanics, Neuroscience, and OMM.

IRB-based protocol and multicenter standardization provided.
