FAQ
Two-Jaw Surgery — frequently asked questions
How is two-jaw surgery different from ASO?
Two-jaw surgery moves the entire upper and lower jaw; ASO moves only the front segments. ASO is less invasive and suits protrusion without a major bite problem.
Will I need orthodontic treatment?
Many two-jaw cases are planned together with orthodontic treatment. Your surgeon will advise after examining your X-rays and CT scan.
How do I know which surgery I need?
Send front and side photos for a preliminary assessment; a final plan is made after an in-person examination with X-rays and CT.
