Is bsso a standard procedure for overbite?

[Deleted member 4310]

Or bimax?

Really confused, which one will make you better looking?

bimax advances both the mandible and the lower maxilla.. bsso only the mandible (lower jaw)

if you have a good bite and occlusal plane theoritically you just need bsso and ortho treatment but its rare i guess

so both are used to treat overbites depending on the case, your surgeon will know better

then bsso seems like a better solution, my maxilla is top-tier.

My upper lip protrudes way more than my lower lip, it looks very subhuman and my upper teeth almost cover my lower.

soft tissue usually doesnt show much, you need to see how your teeth are when you bite


try to open your mouth and jut your lower jaw (bring it forward) and guess if the teeth are in a parallel line and would fit with some orthodontic braces

its not only advancement that could be needed, you might need a rotation of the maxilla but if you have a good occlusal plane then not

I did and my teeth align almost perfectly when I jut as much as I can

Also wouldn't your dentist remark on your teeth at some Point? I have done regular checkups once a year for my whole Life and no dentist has ever said something about my bite.

an overbite in an adult normally needs a bimax

Since it's an overbite the BSSO movement would be larger than any LeFort I advancement that may be also necessary.

When the mandible is advanced, a relative expansion occurs, hence an upper arch expansion is necessary. Sometimes it can be done by only an actual dentoalveolar expansion with orthodontics, but in many occasions a skeletal expansion is needed or at least very recommended.

Besides, patients with overbites tend to have an upper jaw that is compensating for it.

These are the reasons why in treating persons with overbites adding an upper jaw skeletal treatment is advisable. That is normally done by adding a 3-piece Le Fort 1 osteotomy to the BSSO. I always suggest to the patient and orthodontist to address the expansion with MSE prior to the orthognathic surgery, but even in some of those cases an upper jaw surgery is still needed along with the BSSO.

Hope this helps.
