Lateral Joint Loading for the Jaw?

People have asked before if it's possible to do LSJL for the spine.  So far LSJL has only been done for the arms and legs and there's more research done on this field.  Here's a study on lateral loading for the jaw that predates the LSJL longitudinal growth studies that may provide some insight on how to grow taller via the spine or how to get a bigger jaw.

Influence of extraoral lateral force loading on the mandible in the mandibular development of growing rats.

"Thirty growing Wistar rats were divided into 3 groups: control, sham, and experimental. To determine longitudinal developmental changes, each animal was placed under anesthesia and immobilized in a custom-built body retainer. In the experimental group, a fixing device of aluminum was fitted to the zygomatic arch. Lateral force was then applied to the mandible with an open coil for 2 weeks. Absolute lengths and perpendicular heights from the baseline of the lower border of the mandible were measured.
Lateral force induced the mandible to shift toward the nonloaded side; absolute mandibular length at menton-condylion on the side where the load was applied was greater than that in the control group. No difference from the control group was noted on the nonloaded side, and there were no significant differences in perpendicular heights. Lateral loading on the mandible resulted in histopathologic changes: (1) on the side where the load was applied, the cartilaginous zone hypertrophied in the highest margin of the condylar head, the erosive zone expanded, and the width of the mandibular neck decreased; (2) the chondrocyte layer shifted to the medial side on the nonloaded side, and cartilaginous ossification occurred in the lateral direction immediately below the chondrocyte layer, which deformed the mandibular neck toward the medial side and caused asymmetric development of the mandible."

"A fixation device for loading lateral force onto the mandible was attached to the zygomatic arch. It was made of aluminum and was 7 mm wide, 50 mm long, and 0.5 mm thick. The device was fixed bilaterally to the cheek bones (horizontal to the Frankfort plane and immediately below the orbit) with a stainless steel wire with a diameter of 0.3 mm, so that the device passed under the lower border of the mandible. In the experimental group, a hole was made in the left mandibular incisor cervical area, and an open coil spring was ligated to the tooth by using a 0.25 mm stainless steel wire. The device and the coil spring were bound with a stainless screw. The force was loaded to displace the mandibular central incisor 2 mm to the right of the maxillary central incisor. The open coil spring, made of stainless steel containing nickel and chromium, measured 0.25 mm thick, 1.02 mm in diameter, and 7.0 mm long. In the load-shift curve obtained in a preliminary experiment with this coil spring, 2 mm of compression provided about a 15-g force. The direction of the force was assumed to be parallel to the Frankfort plane."<-The force used in the LSJL studies was 0.5N which is much less force.

"The lateral force loaded on the mandible was 15 g; at that level, the rats could move the mandible back to its normal position by themselves when awake. Force was loaded for 24 hours a day."<-LSJL loading is intermittent.

At 2 weeks the absolute mandibular length increased from 17 to 18.  That is huge.  There was no change in the control group.

B and D are loaded side and A and C are non-loaded.  It's hard to tell if there's any evidence of new mesenchymal chondrogenesis or articular cartilage endochondral ossification which would be what increases height.  However, the control group did not grow at all indicating that this is not merely an increase in growth rate.

So lateral loading of the mandible increases it's length and perhaps intermittent loading could provide this increase without the deformity.  You could also load both sides equally.  Growth can be stimulated in the mandible by lateral loading.  No clamp is likely needed and you can just use your hands.  Ultrasound has been tested on the condyle as well.
