Your Face,
Your Jaw Surgery

Upload your profile

Take a side profile photo with a neutral expression. Jaw-Sim Labs works with any standard selfie or portrait.

Place landmarks & curves

Mark key facial points — nasion, maxilla, pogonion — then fit Bezier curves to your jaw contour for pixel-precise tracking.

Simulate & export

Adjust surgical parameters in millimeters — maxillary advancement, mandibular setback, rotation — and see results in real time.

Simulate Le Fort I and bilateral sagittal split osteotomy with independent maxillary and mandibular controls.

Simulate Le Fort I osteotomy with precise maxillary advancement, impaction, and rotation controls.

Bilateral sagittal split osteotomy with independent mandibular advancement, setback, and rotation.

Jaw angle implants and infraorbital rim implants for patients considering combined procedures.

Add midface projection and undereye support with infraorbital rim implant simulation.

Add chin horizontal and vertical projection to your simulation to fix chin recession.

Large language models don't know where your maxilla is, or how it might realistically move. They can give you a pretty picture, but it may not reflect actual surgical movement. Jaw-Sim Labs simulates real orthognathic parameters — you control exact millimeter movements along actual anatomical vectors, fitted to your own facial contour with Bezier curves. The result is a geometrically realistic simulation, not an artistic interpretation. If you are seriously consideringsurgery, you should you tools that can actually simulate it - not tools that wing it.

This tool is for anyone considering jaw surgery. You're committing to your face changing when you sign up for this surgery, but patients are often left in the dark about what their face is going to look like afterwards. Some surgeons may show you morphs when planning, but this is often well after you commit to a surgeon and have already paid thousands of dollars in consultation fees and maybe even dropped a down payment. That's a tremendous amount of time and money just to have an idea of what your face might look like. So why not try out a much less expensive tool that gives you the freedom to test out how different movements and procedures can better help you meet your goals?

Jaw-Sim Labs approximates surgical movements using a single image rather than a full scan of your skull, so it cannot account for how soft tissue will react. Since we also are not using a scan of your skull, the exact movements of your jaw surgery may differ from the simulation. However, everything in the simulation will give you an idea of the general movements that might make snese for your face and desired outcomes as the patient so you can better voice your desires to your surgeon.

Yes. Your simulation is saved to your account. You can come back, adjust the surgical parameters, and re-export as many times as you want on the same photo. You're paying for the photo slot, not per export.

Standard gives you one photo simulation with full DJS and genioplasty controls. Pro gives you up to three photos and unlocks the cosmetic tab — jaw angle implants and infraorbital rim implants — for patients considering combined orthognathic and cosmetic procedures.

A standard side profile photo with a neutral expression and your mouth closed. Natural lighting works best. The photo should show your full face from the side. Try to avoiding odd angles or backgrounds that are similar to your hair or skin tone, and leave some space around your head for the background so your face has enough space on the screen during the simulation.
