What does auto rotation of the mandible mean with regards to orthodontic surgery?

Orthognathic surg: Autorotation of the mandible is a term to describe the rotation of the lower jaw around an axis theoretically drawn horizontally through the jaw joints on both sides. If the upper jaw has been surgically repositioned, often the lower jaw is allowed to rotate so that the teeth contact in a normal way. It is a "tern of the trade, ' so to speak.

Close jaw more: Changing the position of the teeth with surgical orthodontics can move your teeth out of the way so that your lower jaw can close further and into a more desirable position. This is referred to as autorotation of the mandible. An orthodontist can describe it for you with visual aids.

Forward rotation: Auto rotation during mandibular surgery will allow forward movement of the mandible so the existing malocclusion can be corrected. A very common surgical approach for correction of an anterior open bite.

More chin in profile: You are talking about a maxillary impaction surgery. As the maxilla is moved up, the lower jaw will close further up and give you more chin and come forward.

See below: It means moving the upper jaw up so the lower jaw can follow it by its normal closing rotation.

Closing or opening: If the upper jaw is moved up or down in the back then the lower teeth will close to meet them. Since the lower jaw joint is in front of the ear, the jaw rotates down and back or up and forward depending on where the upper jaw is placed.

Rotation to new bite: Orthognathic surgery that repositions the maxilla (upper jaw) allows the mandible and its' hinged joint to auto-rotate into occlusion. If the posterior of upper jaw is placed superiorly, the lower jaw will auto-rotate counter-clockwise (bring chin forward) as it closes into the new occlusal scheme. It works in reverse as well.

Reaction: Reaction to surgical repositioning of the upper jaw. If, for example th upper jaw is lifted, the lower jaw will autorotate upward and forward. This can help reduce front-to-back lower jaw retrusion.
