The Mentor CPG (Contour Profile Gel) Implant
Known simply as the CPG, Mentor's cohesive gel filled implant is becoming increasingly popular. Recognizing the increasing popularity of the MM version of the 410, Mentor initially made a single size of the CPG, which was similar to the MM. They also believed that some surgeons considered the 410 to be too firm, so they formulated their gel to be a little softer than the 410.
Subsequently, the CPG line has been expanded to include 4 different shapes of implants in Europe. However, only the original reduced height version has been available.
