What is it indicated for?
The Lorenz BLUE Device is intended as a bone stabilizer, and distraction devices when correction of congenital deficiencies or post traumatic defects of oral (including the mandible, alveolar ridge, palate, and symphysis areas), cranial, and maxillo-facial bone require gradual distraction. This is the same intended use as previously cleared for the Lorenz Distraction System (K992952).
