Soft-tissue augmentation devices: longevity of effects

Abstract

The search for an ideal device or technique intended for soft-tissue augmentation has led to the development of a myriad of procedures and products. Currently, minimally invasive options can be sub-divided into those which offer temporary or permanent effects. The durability of results offered by these techniques and devices are presented here, focusing on products approved in the United States. Collagens and hyaluronic acid-based products offer effective results that are short term, generally providing a few months of augmentation. Fat replacement offers variable results and devices, such as polymethylmethacrylate, can give permanent correction. Long-lasting devices that are not permanent, such as calcium hydroxylapatite and poly-L-lactic acid, fill the gap between temporary and permanent devices, and can offer effective, durable correction.
