Occlusal Plane

- The occlusal plane is a line across the occlusion
- The occlusal plane should be parallel to a line between the eyes (inter-pupillary line)
- If the occlusal plane is slightly tipped one can improve / mask it by bonding the front teeth on a slant
- If the occlusal plane is significantly tipped, upper and lower jaw surgery is required to fix it
- Upper jaw surgery is called a Le Forte I osteotomy
- Lower jaw surgery is called BSSO (Bilateral Sagittal Split Osteotomy)
