Double jaw surgery

Occlusal plane rotation for mouth protrusion

A published technique that rotates the occlusal plane instead of simply retracting the mouth, correcting protrusion without a collapsed lip line and keeping the nose–lip–chin profile continuous.

Who it suits

Mouth protrusion combined with a long face or receding chin
Patients worried about a sunken mouth after jaw surgery

Technique highlights

Corrects protrusion without over-retracting the lips
Restores a continuous profile from nose to chin tip

Surgical steps

Analyse occlusal plane angle and lip position on the lateral view
Plan a combined rotation of both jaws rather than a pure setback

Recovery & aftercare

Same pathway as the hospital's standard double jaw surgery

Risks & things to consider

Requires assessment of soft tissue proportion, not the bite alone

Frequently asked questions

How does occlusal plane rotation differ from simple setback?

A pure horizontal setback flattens the lips; rotating the whole occlusal plane changes the angle of the dental complex, reducing protrusion while keeping lip fullness.
