1. A temporary implantable screw for preserving the integrity of an oral socket, the screw comprising:
a healing abutment head wherein the head ranges in height from about 3 mm to about 5 mm and ranges in diameter at a base of the head from about 3 mm to about 6 mm, wherein the head has a straight wall design defined by a top surface, a bottom base, and side surfaces, wherein the head has smooth rounded edges between the top surface and the side surfaces and between the bottom base and the side surfaces; an unthreaded neck extending from the bottom base; and a shaft for anchoring the screw in the bone, the shaft including a threaded proximal end extending from the neck and a threaded distal end opposite the proximal end, the shaft comprising a middle portion between the proximal end and the distal end, the shaft having a thread extending continuously across the shaft from the proximal end, through the middle portion to the distal end, the thread being adapted to penetrate bone tissue; wherein the screw is monolithic and has an arcuate shape between the bottom base of the head and the proximal end of the shaft, a major diameter of the thread is about 2.0 mm or less and a minor diameter of the thread is about 1.8 mm or less, and the minor diameter is less than the major diameter. |
