The most popular chin implant is from solid silicone. These are Dr. Z’s preferences as they provide firm support but are also flexible when needed, can be carved to make fine adjustments in size or shape, and can be removed easily if necessary. They are not associated with the same issues as liquid silicone breast implants and have been used successfully for many decades. An alternative to silicone is ePTFE, which has many of the benefits of silicone, but allows for some tissue ingrowth, thus would be more difficult to remove. Another material and implant type is the medpore, which is not flexible and has more ingrowth, thus even harder to remove.
