IMPLANT INFORMATION about Head/Brain/Nerves

   
What … for? (Indications)

1)    Hard structures
Bone substitutes and/or fixing materials are used to maintain bone structures of the skull or spine after e.g. diseases or traumata.

2)   Soft structures
Membranes, nerves, brain is used to maintain or reconstruct soft tissues.

3)   Fluids
Fluids are substituted to manage the flow of fluids.

4)   Nerv (influencing)
Nerv influencing implants are used to stimulate or influence nerves or brain, e. g. at chronic pain (neurostimulation).
