Weak Chin - Jaw Surgery Vs. Chin Implant?

Hi, I have suffered from TMJ pain for about 4 years. I have tried various methods (night guard, soft foods, massage, etc) with no success. I have made an appointment with a mouth doctor. I have a weak/small chin, but not a terrible underbite (jaw wise). I have been considering a Chin implant ever since I discovered it's possible. For TMJ, I understand open jaw surgery is last resort but also that it restructures the jaw and might give me a better chin? Is it wrong to think of open jaw surgery as killing 2 birds with one stone?

Chin implant or mandibular osteotomies will improve weak chin

A small to medium-sized chin implant placed through a submental incision would give a stronger chin profile. Mandibular osteotomies or open jaw surgery could also strengthen your chin. However, neither of these two procedures will address nor improve your TMJ issues.
Chin implants are inserted throughout sub mental approach as an outpatient surgical procedure under local anesthesia.
Mandibular osteotomy is performed under general anesthesia and usually requires a 24-48 hour stay in the hospital. If the teeth are out of alignment significantly, this may be the best route to proceed with.

Weak chin-jaw surgery vs chin implant

The first thing is you need a correct Diagnosis, do you indeed have a weak chin from a small lower jaw or do you have an isolated weak/small chin. Considering you acknowledge your underbite, you likely have a small/retrognathic mandible. So your best option would be to see a plastic surgeon whom is familiar with tooth/skeletal relationships to discuss your options. Not all plastic surgeons are the same with regards to this topic, do your research and find one who can and routinely performs either corrective jaw surgery or placement of chin implants. In regards to your TMJ pain, your malocclusion (underbite) is likely contributing to this, correcting your occlusion orthodontically would be a good place to start so having a consultation with an orthodontist would be another valuable consult for you to help you decide what your best options would be.good luck

In this situation, it is not wrong to think of orthognathic surgery as a two for one type procedure.  Advancing the lower jaw with bone grafts or implants will alter the projection of your chin while possibly alleviating your TMJ symptoms at the same time.  After the jaw augmentation if the chin projection is not corrected sufficiently a chin augmentation can be done at the same time.  However, without a physical exam it is difficult for me to say definitively whether or not you would still require a chin implant in conjunction with the mandibular advancement.  Be sure to confirm that your doctor is a board certified oral maxillofacial surgeon before your consultation.  It would also be helpful to obtain any recent imaging studies you may have from a dentist or orthodontist and bring them to your consultation.

Be well and good luck!


Chin Implant Surgery may improve the appearance of your weak chin.

You seem to be an ideal candidate for Chin Implant Surgery. You would have improvement in the appearance of your chin and jawline. This would also have the added benefit of making your nose look smaller. Chin Implant surgery is relatively inexpensive, and takes less than 30 minutes. Downtime is about a week, and your results are permanent.

I'm not a big fan of sliding genioplasty surgery (surgically advancing your chin-bone forward).

I've attached a link to my Chin Implant photos for your perusal.

I hope this is helpful for you.

If your bite is not contributing to the TMJ pain. Then it is a chin implant and then deal with the TMJ. TMJ surgery will not affect the chin, surgery on the mandible may  improve the profile some.

Chin augmentation

 You could have some chin enhancement and usually a chin implant is used.  Occasionally a sliding genioplasty is done but fewer surgeons do these.  I'd look at it as a separate issue from your TMJ.

If occlusion of your teeth, your bite, is right then a Chin implant will give you a outstanding result

Silastic silicone chin implants in the proper patient placed under the on the bone of the jaw give wonderful long lasting results. Make sure your plastic surgeon evaluates you bite and certifies that it is right before going ahead with the chin implant. If you have a bad bite you might be able to have them both corrected at the same time. An extended chin implant in your case will give you a lovely result that will bring a nice balance to your face. I feel sliding genioplasty will work but is much more involved with more likely undesirable side effects.

TMJ surgery and chin and neck contours

In many instances jaw surgery can accomplish both goals. However, traditionally these are different surgical proceduress. TMj surgery typically does not improve chin projection whereas a SSO for malocclusion or sliding genioplasty can definitively achieve chin enlargement. The use of submental liposuction can enhance the result as well.

This would be a good option. you would be getting both of these things done at the same time given that moving your jaw forward is the answer.

In looking at your photo, you appeared to be an ideal candidate for a nice chin implant. The procedure is very easy to perform in skilled hands. You should achieve an excellent aesthetic facial balance that would enhance your already beautiful face.

Unless you have a severe malocclusion problem necessitating major reconstructive or orthognathic surgery, I would strongly advise you to go with the chin implant. Except in cases of severe malocclusion, the TMJ entity is another matter unrelated to the cosmetic aspects of your chin. I would advise you to address the TMJ as a separate entity.
