IDS-55250: Penguin II device
The Penguin II device uses specialized plugs designed to measure implant stability and osseointegration level. These plugs emit magnetic resonance and capture the returning frequency, translating it into precise ISQ levels. Exclusively designed for use with the Penguin device, these plugs are compatible with different platforms (each plug for a different platform, for selection). Crafted from top-quality materials, they are reusable and capable of enduring up to 20 sterilizations in an autoclave.
