In the United States, four manufacturers currently market FDA (Food and Drug Administration) approved mammary prostheses. These are Allergan®, Mentor®, Sientra®, and Ideal®. Dr. Laverson uses implants from all four manufacturers, depending on what he believes is best for you based on your size, shape, and texture request, whether or not you want shaped or round implants, whether or not you want silicone gel or salt water implants, and also based on your presenting breast anatomy. From a quality standpoint, all four manufacturers produce the best implants available, have unsurpassed standards for design and manufacture, and all have been extensively laboratory tested and have been in safe clinical use for millions of patients for many years.
