A dental implant is essentially a substitute for a natural root, and commonly, it is screw or cylinder shaped. Each implant is placed into a socket carefully drilled at the precise location of the intended tooth. Often, the implant can be placed at the same time as tooth removal.
If an implant has a screw-thread on its outer surface,, it can be screwed into position,; if it does not, it is usually tapped into place. The main aim during implant placement is to achieve close contact with the surrounding bone. This creates an initial stability, which is steadily enhanced by further growth of bone into microscopic roughnesses on the implant surface over time.
To support replacement teeth, dental implants usually have some form of an internal screw thread or post space that allows a variety of components to be fitted. Once fitted, these components provide the foundation for long-term support of crowns, bridges or dentures.
