Is there a way to have a chin implant with extended sides to fill in and smooth out the jawline without causing bone loss?

You shouldn’t have bone loss with a chin implant, nor should you need fillers to smooth out depressions. It sounds like you were not fitted properly. Spend some time interviewing the most expert facial plastic surgeons in your area to find one who gets consistently great results with chin implants. Once you find this expert, you’ll get all of the other answers to your questions, too. I hope this helps.

There are several treatment options. If you elect to replace the implant with another implant then I would recommend a custom implant design that is created from a 3 -D CT scan. A genioplasty is another viable consideration because your own chin can be moved forward up to 9-10 mm. A genioplasty can add height as well if that is necessary. Both procedures can be performed in the office with IV sedation and require 4-7 days recovery depending on age of the patient. 

Thank you for sending your question.  An extended anatomic implant is the commonest implant used in my practice.  This implant provides a natural transition as the implant extends laterally.    Bone loss while common is not often clinically significant.   See a surgeon who performs chin implants frequently and review product designs from the implant catalog.   Together you can pick the implant that will give you the best chance of obtaining the look you are hoping for.   Good luck with our procedure.
