Mike,
Thanks for your question regarding chin augmentation material. We use a company called Impantech for our implants. We usually us silicone implants. Silicone is a polymer of siloxane. It can be made into a liquid, gel, semi-solid or solid depending on how many molecules you link together. In the case of chin implants it is a flexible solid, ie bendable but maintains its shape. We also will us autologous fat to augment the chin in certain circumstances. I hope you find this information helpful. Please feel free to contact us with any further questions.
