What is it indicated for?
OSSDSIGN Cranioplug is an implant intended to cover and plug holes drilled into the skull during surgery and to reattach cranial bone removed during surgery. These osseous defects are surgically created and are not intrinsic to the stability of the bony structure. The ceramic component of Cranioplug resorbs and is replaced with bone during the healing process. Cranioplug is indicated for use in adults and adolescents age 12 and older.
Indications for use as stated in the FDA summary.
