ABSTRACT:
An implantable screw for maintaining space during bone grafting procedures is provided, where the screw has a highly-polished contoured head having a region adapted to support soft tissue, a threaded shaft and a tip adapted to penetrate bone tissue. Also provided, a device combining multiple implantable screws in series in order to increase the available space to grow new bone and a method for implanting the implantable screw. The implantable screws provided may be used in conjunction with bone graft materials and are removable once a desired amount of new bone is generated.
