Mandibular advancement and setback are done with which procedure?

Genioplasty
LeFort I
BSSO
Invisalign

The correct answer is: BSSO

Mandibular advancement (moving the lower jaw forward) and setback (moving the lower jaw backward) are typically achieved through a procedure known as BSSO, which stands for Bilateral Sagittal Split Osteotomy. This procedure involves surgically cutting and repositioning the mandible to correct the position of the lower jaw. Genioplasty, on the other hand, involves reshaping the chin, LeFort I is a procedure involving the upper jaw, and Invisalign is a type of clear aligner system used for orthodontic treatment, none of which are directly related to mandibular advancement and setback.
