Single jaw surgery for for patients with skeletal class II retrognathia vs double jaw surgery OVERBITECELS GTFIH

So in my last post I was asking about my surgeons plan of only moving my upper jaw combined with a genioplasty. I already have a class 1 bite because of camoflague treatment, but also a gummy smile, so i am still a candidate for this case.

Next week we will discuss the 3d plan and play around with the planning software to get the genioplasty right for my aesthetic eye.

I also recently had a ct scan and got in on my pc, its really interesting to play around with your own skull in 3d.

While doing my research on this topic I found this study comparing standart DJS vs a single jaw surgery with atorotation: https://sci-hub.se/10.1016/j.bjoms.2019.10.309

Overall the movements are very similar in absolute mm for both groups. Which makes me wonder, why do I not see more examples of single jaw surgery with autorotation.

And the interesting part is this: However, there was a significant difference in median (range) surgical posterior movement relapse at point B (conventional group -1.7 (-2.3 to -0.5) mm; experimental group -0.6 (-1.0 to 1.0) mm; p=0.032). Mandibular advancement with mandibular autorotation is therefore a more stable procedure than mandibular advancement with bilateral sagittal split osteotomy in patients with skeletal class II retrognathia.

There is this study too: https://pubmed.ncbi.nlm.nih.gov/34456281/


So looksmaxxers: What is your opinion on double vs single jaw surgery? It seems like single jaw surgery mogs because it has way less complications without BSSO involvement and overall stability is way better.

From my last post and general googling, I have found some cases with single jaw surgery which look really good. For example:

Both of these had genioplasty, the second one had condylar resorbtion, but thats rarer ir males and still a higher risk with BSSO involvement afaik.

usually niggas have to do both because of the bite plane and teeth alignment, unless one of ur jaws is perfectly in place - which is usually not the case.

Yeah, makes sense, my surgeon said that I dont need BSSO for 2 reasons:
1) My jaws are already big enough and i don't have a recessed lower jaw, just the gonion(chin)

2) I had camouflage orthodontics, so my bite and teeth inclination is already good, only thing he mentioned that the could do a bit of extra CCW(counterclockwise) rotation to make my mandible rotate ever more forward.

So you just need Upper jaw surgery?

Yes, my surgeon thinks that is the most sane and effective approach. At first we were discussing only doing genioplasty, but I don't like my gummy smile and botox/gum lasering just looks weird after compared to impaction before afters.

I look recessed af from side profile and this site made me think that I need DJS regardless.

I could probably benefit aesthetically from it, but then we would have to move both jaws forward to create an even occlusion.

So, if the goal is not to fuck up my already good occlusion and to advance my lower third as far as posible (within aesthetic limits) , then upper jaw surgery with mandibular autorotation is the way to go. Add genioplasty as needed and BOOM, gigachad.

EDIT: I just realized you can see how my bone is still not as dense in the line between my incisors and nose, that is from SARPE which I had 2 years ago.
