For the sphenoid bone, the lower part of the left side should go up. The occipital bone should also rise on the left side. In the picture on the left compared to CT, you can see the change from before to after treatment.
For the occlusal surface of the maxilla, if the lower right side is raised up using an orthodontic screw, the sphenoid bone is further distorted. If you look at the CT comparison after the treatment, you can see that the left side went down after treatment.
If you look at the CT comparison of the occipital bone before and after treatment, it can be seen that the lower left side has risen up after treatment.
So, are these changes a therapeutic change that can be achieved throughout an artificial osteopathy?
This misalignment is improved by making the three-dimensional position of the lower jaw in a position where the skull moves well. This is a change that happens automatically when you wear the MCB splint. A good left and right position of the lower jaw allows the sphenoid bone to move normally
A good anteroposterior position of the lower jaw normally moves the temporal bone.
This is because the height of the teeth at this time moves the occipital bone normally
Bilateral balanced Bodily Expansion(Maxilla)
As for the maxilla, the cranial torsion was improved by the use of the mcb splint, so balanced expansion was achieved in both directions with MARPE, resulting in parallel expansion rather than oblique motion, whereas the mandibular teeth were tilted with ALF.
In the maxilla, it was moved forward by traction with The Crane (Face mask) at the same time as the skeletal expansion.
In the mandible, it was moved forward movement by mcb splint at the same time as the dental expansion by ALF.
