Mandibular defects, often due to tumors, considerably impair life expectancy. The standard treatment is to reconstruct the mandible with a fibula graft using a freehand technique. With the color-coded L1® Mandible ReconGuide, the focus is on holistic simplification of this demanding surgical procedure. This is facilitated not only by gold-marked fixing screws and pre-bent implants adapted to the guide, but also by the red screwdriver handle to ensure the exclusive use in the septic mandible area. This cleverly contrived concept is consequently transmitted to the storage system. This leads to reduced OR time and to safe, reliable procedures.
