Why Can't a 14 Year-old Have a Chin Implant?

I agree with Dr. Blinski.  Facial growth and development take longer to fully develop in boys than in girls, and isn't complete until a minimum of 17-18.

Chin implants shouldn't really be placed until someone's facial growth is complete. The jaw will likely continue to grow if your son is 14 so placing an implant now may ultimately produce an improper result.

If your son has a disfigurement, like you describe, this may be å more significant issue that would be better addressed by a craniofacial surgeon or oral surgery. They can assess your son to see if surgery to change the position of the upper and/or lower jaw would help with your son's facial issues.

It is important to ascertain that growth has been completed prior to undergoing surgery. In males, this is frequently, but not always, around age 18. Additionally, having the maturity to participate in the decision making process is also significant. There are no hard and fast rules but certainly there may be need for multi specialty consultation so definitely planning ahead is a good way to proceed.
