Often the implant can be placed at the same time as removal of the tooth all on the same day. If an implant has a screw-thread on its outer surface it can be screwed into position and if it does not, it is usually tapped into place.
The main aim during installation of any implant is to achieve immediate close contact with the surrounding bone. This creates an initial stability, which over time is steadily enhanced by further growth of bone into microscopic roughnesses on the implant surface.
In order to support replacement teeth, dental implants normally have some form of 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.
