A screw made of human bone.

The human bone material from which the Shark Screw® graft is made is recognized, accepted and converted into its own bone by the body. Renouncing metal or absorbable materials such as polylactide minimizes complications, inflammation and irritation; the bone can heal faster and with less pain. For patients, this means significant relief, a more comfortable healing process and shorter, professional downtime.
