Abstract
An endosseous dental implant system comprises a root formed, mechanically retained base and an intimate, inter-locking threaded coronal attachment. The root formed base is comprised of a self-locking, externally threaded, tapered shell, and an anti-rotational internally threaded, countersunk plug which is permanently attached below the coronal surface of the shell, thus forming a single unit. Internally, the coronal portion of the shell has a downward tapered bevel for locking the anti-rotational coronal attachment to the base once attached via the internal threads of the permanently connected countersunk plug. Self-tapping threads are incorporated into the apex of the root formed base for easy insertion and immediate locking with the osteotomy. Downward from the coronal portion through the midsection of the root formed base is a specially designed stress distributing thread for uniform loading through the implant site. Finally, to simulate the physiological conditions, the implant system is manufactured from a material that closely replicates the natural dentition.
