secondtimearound, a lot of people get lefort 1 for gummy smile having proper jaws and bite, don't they?
If they have too long a maxilla to any significant extent it will show on the ceph analysis as abnormal.
Cephalometric analysis = God to me, or the closest we have to it.
We know scientific averages of features are more beautiful and cephs are based on averages. Cephs will look at the maxillary length, mandibular length, etc and give it to you all in objective data.
If your scores all come back normal or within a minimal tolerance yet you're still considering jaw surgery you're likely mentally ill. Only exception is perhaps facial asymmetry as that won't show in standard lateral assessment.
Or perhaps sleep apnea patients though I bet almost all of them have low sna and snb angles (recessed).
Cephx.com is great in my opinion.
