Soft tissue implants and fillers.

The number and variety of soft tissue implants and fillers at the clinician's disposal continues to increase rapidly as new materials and bioengineering techniques evolve. The ideal implant for all purposes does not yet exist, so the clinician must be familiar with a wide variety of products for each application. Continued advances in synthetic, allogeneic, and autologous products and experience with existing products will further augment the surgeon's armamentarium in the coming years.
