What is the risk of screw fixation causing degradation of a silicone chin implant?

Placing small bone screws to fixate plates and implants has been performed safely for years. It is the best and most secure technique to avoid migration of the implant. It cannot cause an implant to degrade. It is possible to re-position your current implant or replace it with a new implant. Suturing the implant does not prevent migration of the implant.

Thank you for your question. When placing a chin implant, the most crucial step is creating a pocket under the muscle for the implant to sit in. Some surgeons use a screw to fixate the implant, and some don't. I personally like using a screw just as an insurance policy, and I've never experienced any issues with degradation.

There are numerous misconceptions in your inquiry including that implants degrade over time, screws causing implant degradation and that a 'pocket adjustment' first needs to be done before a new implant is placed later. In reality you can have your existing chin implant removed and replaced immediately in a lower and better position on the bone with screw fixation.
