I am a candidate for orthognathic surgery and would like to know how much I can increase my overjet by changing my teeth' inclinations (they were treated before with camouflage orthodontics). My current overjet is 5 mm. My IMPA (incisor mandibular plane angle) is 106 degrees. Am I correct to believe that the lower teeth can be reclined to around 86 degrees so that my overjet increases by 2 mm? I am unsure how many millimeters I could also gain by proclaining my upper teeth (so that it remains in an aesthetic position). The following are the measurements, U1/NA is 7 degrees, U1 /SN is 87 degrees, U1 to FH is 102 degrees.
Upon review (attachments removed to protect patient's identity) I find an overjet of 5 mm with a normal overbite and camouflage orthodontic treatment. Ideally, the overjet is 2 to 3 mm. As in your case mandible stands behind and the X - ray shows proclined lower anteriors. First, it is necessary to bring them back to normal, and the orthognathic surgery advances mandible. Finally, correcting anteriors proclination and overbite. The provisional diagnosis is Angle's Class II malocclusion with end-on molar relation and proclined maxillary and mandibular anteriors with increased overjet. I would suggest, correction of maxillary and mandibular anterior proclination, molar relation and then overbite and overjet. You would have a fair treatment outcome.

.. sent me the verbatim report of the MRI of the cervical spine and the mastoids.
This, however, is very little to help me as I do not know the exact symptoms you have.
