Will Silicon Implant in Chin and Jawline Need Replaced?

Silcone chin implants are solid so there isn't an issue with leakage over time (unlike silicone breast implants). Chin implants can last years and don't have a certain time frame where they necessarily have to be replaced. Chin implants in general may cause a small amount of resorption of bone over the chin but this is typically minimal and not clinically significant (and isn't a reason to remove the implant).

Dear Ms LizLiz - thanks for your question - the solid silicone implant is a very safe and stable product - with good implant technique and good post-operative care the implant will be incorporated by your body and provide the profile improvement that you are looking for.  While the implant does not change it can create a minor amount of boney resorption on the jaw.   As you age the bone of the jaw will change and if you loose your teeth it may change even more.  This is the only scenario that may require a change or a removal of the implant.  Take care of your teeth and you will do well.

Not necessarily. Chin implants can last many years. I have patient with silicon chin implant who has had them for 20 years. Solid chin implants could cause some bone resorption over many years, since they exert pressure on the bone but this is not the reason to change them. This is true with any implant in the body.
