A subdermal implant is a body modification placed under the skin, allowing the body to heal over the implant and creating a raised design. Such implants fall under the broad category of body modification. Many subdermal implants are made out of silicone, either carved or mold injected. Many people who have subdermal implants use them in conjunction with other types of body modification to create a desired, dramatic effect. This process is also known as a 3-D implant, or pocketing. History The first subdermal implant was implanted in 1994. It is generally agreed upon that they were pioneered by Steve Haworth. In his shop, HTC Body Piercing, in Phoenix, Arizona, he first began these procedures after being asked for a bracelet. He concluded that he could put a row of beads under the woman's wrist to create the effect she desired. This was followed in 1998 by the scientist Kevin Warwick who experimented with both an RFID and an electrode array implant. Since then, many different artists have done many kinds of implants. Some of the well-known names in the industry include Samppa Von Cyborg, Max Yampolskiy, Brian Decker, Emilio Gonzales and Stelarc, who had a cell-cultivated ear implanted on his arm. Types According to the Church of Body Modification, there are two main types of subdermal implants: subdermal (or subcutaneous) implants and transdermal implants. Magnetic subdermal implants also exist. Subdermal "Subdermal implants," as defined by the Church of Body Modification, are completely buried in the dermis. These are used for both cosmetic and medical purposes, such as the contraceptive Norplant, consisting of six levonorgestrel-releasing Silastic capsules, and is placed under the skin of the upper arm, generally a woman’s arm. The cosmetic variant can be molded into any shape desired; though usually made of silicone. However, Teflon variants exist as well. Transdermal Transdermal implants are placed partially under the skin, with the rest exposed. This is done through a process known as "dermal punching". First the implant is placed in between the layers of skin. It is necessary for the part of the implant that will be located under the skin to have a proper shape. This must be one with holes in it (like a figure eight) so that the body will be able to grow around it. Once the implant is placed, the part that will protrude out is exposed using a dermal punch.
