PURPOSE: A regenerated bone screw and a regenerated bone cover mesh are provided to fix regenerated bone tissue to a damaged alveolar bone, cover the operation area of alveolar bone, and protect the exposure of a screw head part, thereby preventing the damage due to external impact. CONSTITUTION: A regenerated bone screw(100) comprises a body unit(10), a screw thread(20), and a head unit(30). The body unit is made of a titanium metal material, and combines an alveolar bone and a regenerated bone tissue. The screw thread is formed helically along the surface of the body unit to be a male screw. A cross shaped groove or slotted groove(31) is formed on the head unit. A regenerated bone cover mesh comprises a center body, a plurality of long foot shaped units, and a plurality of round shaped protrusion units. |
