Which is better for me: sliding genioplasty or chin implant?

Chin implants work best when you only need improvement in the horizontal direction. You need an increase in your height as well, so a sliding genioplasty would give you a better result. A sliding genioplasty in experienced hands is about a 30min procedure with same day discharge home.

I perform both procedures and for horizontal advancements greater than 5 mm I prefer the genioplasty procedure. Both procedures are performed in the office with intravenous sedation. The genioplasty procedure moves your own chin forward and provides the most natural results. The muscles of the chin will re-attach to the bone as opposed to a chin implant that becomes encapsulated. Based on your photos, you would benefit from an advancement greater than 5 mm so I would recommend a genioplasty. In my experience, the recovery times are similar for both procedures. Orthognathic surgery is unnecessary if you are satisfied with your bite . Good luck

I think your idea of sliding genioplasty may not be the orthognathic surgery that you mentioned in your question.  Typically orthognathic surgery addresses your bite and can involve moving her entire mandible forward in a procedure called bilateral sagittal split osteotomy or BSSO.  This procedure is involved and has a prolonged recovery period.  A sliding genioplasty only involves moving the bottom portion of the mandible bone in either the horizontal versus vertical plane (without affecting your bite).  The sliding genioplasty is more versatile as I can give you vertical height as well as anterior projection.  A chin implant typically only gives you anterior projection and if placed very low can give you a slight vertical augmentation.  The recovery period for both a sliding genioplasty inch implant are fairly similar.  Depending on the area, the cost may be different however.

If you are looking for the the most economical approach to your chin augmentation then an implant would be used. If you are looking for the best aesthetic and long-term result than a sliding genioplasty would be better. With a short chin and overbite your chin augmentation needs both horizontal augmentation with some vertical increase for which a sliding geniplasty accomplished these changes the best.

A sliding genioplasty is performed by an oral surgeon under general anesthesia in a hospital setting with an overnight stay at the hospital and is much more invasive.  A sliding genioplasty is performed when the teeth are significantly out of alignment.  A chin implant is placed under local anesthesia which takes approximately 30 minutes, and It is much less invasive.

Dear Vivid1860,If you do not have any current bite issues then a sliding genioplasty is not needed. Genioplasty is a very involved procedure and it has a long post operative recovery. You should be an ideal candidate for chin augmentation to provide more projection to your weak chin. I would combine this with sub-mental liposuction to balance your facial profile and overall facial aesthetic nicely. I like to use a silastic chin implant and these come in many shapes and sizes. I prefer to use a small incision placed under the chin which allows the patient a speedy recovery and less risk of infection then an intra-oral incision. See some experts in the field and have imaging performed to show you how chin augmentation will improve your facial aesthetics. See many before and afters in the link below and the imaging process in the video attached. Best regards, Michael V. Elam, M.D.
 

You have to consider the fact that the lower jaw is underdeveloped; and the 'overbite' is leading to the 'deep' fold between the lip and chin. You need some 'vertical' increase in height as well as forward projection, if you only do a chin surgery. A genioplasty can accomplish that for you; whereas the implant won't.
