Crisalix has a built-in catalog with more than 6500 references for breast implants. You can customize this catalog so that only the brands and references that you mostly work with are shown. If you cannot see any implant at all or only some brands are displayed, then you must check the settings of your simulator.
For that, you can follow the steps described in this article Defining the breast implants you use most commonly or check the Settings of your simulator on the left-hand side menu inside the simulator (Settings > Implant Catalog).
