Implants are a fairly modern practice that involves placing objects underneath the skin. Silicone and titanium are common materials that are used for implants.

There are different types of implants that range from microdermal implants, transdermal, eyeball, dental, and magnetic implants.

Generally these type of body modification implants are solely for aesthetics and do not provide any other benefit.

If you decide to get an implant, consider doing heavy research, as if  the implant is not performed properly, infection, migration, and rejection may occur. You want to find a practitioner who is familiar with implants.
