The most common chin implant for women used by Dr. Moynihan is a Mittleman prejowl extended implant. Using a silastic implant (a safe, silicone rubber) has two advantages: It allows sculpting of the implant to beautifully match your unique facial anatomy. In the rare event that you are unhappy with the implant, no matter how much time has passed, it can be removed with little difficulty and the ability to restore the previous anatomic setup. For males, who typically want a squarer, more structured jawline, a Terrino implant can create a more dramatic masculinization.
