Orthodontic Decompensation ahead of surgery

[morgan118]

Hi all, I've decided to have DJS for mostly cosmetic reasons

My current state is a class 1 bite with a well developed face apart from the mandible which is small. For more context please see previous posts I have made.

One option is to have surgery first however I would only be able to achieve around 4mm forward movement to the mandible with this option and it would be through CCW rotation alone as I do not want to move the entire maxilla forward.

The second option is to have Orthodontic Decompensation ahead of surgery which I believe would provide the best cosmetic outcome by far. My orthodontist claims to be able to achieve a 7mm overjet without having any premolar extractions (I have just had my wisdom teeth removed to make space for this).

Please see linked a video simulation of the proposed tooth movements as I would be interested to know peoples opinions on it. Also let me know if you need anymore information as I would be happy to provide this.

I'm extremely skeptical the molars can be moved posteriorly like that. These are large, double rooted teeth, and I don't think it's possible to use enough force to safely move them that distance. I could be wrong, but having been in braces and tried to move molars, it was nearly impossible front to back. In youth, headgear can maybe do that, but if you're an adult, I highly doubt it. I'd get more opinions on that movement.
