Implant materials for jawline and chin?

The type of material depends on what the final goal will be and where the starting point is. Do you need an implant ,is an injection possible or is a procedure on the bone the best option?

Typically you can choose between Silastic (popular relatively inexpensive); a type of acrylic/ plastic (Porex is a common one); Gortex-like (most biocompatible more cost) and even Coral-like (hydroxyapatite). In the chin area, they all 'work' but they do yield different appearances due to their contours, ability to shape at surgery, Density and palpability.  The choice 'should ' be based upon the best balance for your face including the present shape of the chin and the amount of muscle activity present.
