Should the lowered area be treated with an orthodontic screw to lift it up? The tilt of the maxilla is caused by the twisting of the sphenoid bone. In other words, the side where the sphenoid bone descends also descends the maxilla (A). If you come down at the same time like this, you can put the lower side up. However, even if a lot of force is applied to the lowered part, the sphenoid bone does not move and the teeth move mainly. This is because the sphenoid bone moves well in the twisting direction but does not move in the opposite direction.

However, contrary to the inclination of the maxilla, the sphenoid bone may be distorted (B). In this case, if an upward force is applied to the lowered part, the sphenoid bone moves well in the wrong direction, so it moves well. In other words, the sphenoid bone is played even more. The occlusal slope of the maxilla has been treated, but the sphenoid bone is further twisted. In other words, if you do not know the distortion of the sphenoid bone and treat the maxillary inclination, the skull may become more twisted.

For maxillary occlusal canting treatment, while using MARPE to increase the movement of the skull, use the MCB splint at the same time to determine the distorted state of the sphenoid bone, and then treat the distortion of the sphenoid bone. You have to make the cranial movement better.

Even if the teeth are horizontal, the skull bone does not move normally (C).

Even if the teeth fit well, the bones of the skull do not move well (C).

When the MCB splint is installed, I can feel that all the skulls and the whole body twisted in three dimensions (vertical Axis/YAW, transverse Axis/PITCH, A-P Axis/ROLL) change to their respective good positions.

So, orthodontists must study osteopathy for their patients and themselves.
