How does sliding genioplasty affect the position of lower teeth?

I've been doing sliding genioplasty for more than a decade, since it is a neatly superior procedure compared with chin implants.The teeth are not affected, the bony cut (osteotomy) is below the teeth, is a marginal fragment of jaw that is moved forward.

The position of the lower teeth will not be affected by a sliding genioplasty. This is because the part of the chin that is moved forward is below the level of the lower teeth. Therefore, the lower teeth position is not changed. There are other jaw procedures which do move the lower teeth position but a sliding genioplasty does not. I recommend you make a consultation with Board Certified Plastic Surgeon to learn more.

Unlike its bigger cousin (mandibular osteotomy or BSSO), a sliding genioplasty only moves the chin bone below the level of the front lower teeth. This one's bite is not affected.

the actual 'genioplasty' is done 'below' the lower incisors roots and does not change the teeth location. Think of it as cutting 'under' the roots and moving only that part forward. Like sliding a middle drawer forward and leaving the top drawer where it is. lol strange analogy
