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
for illustrated information.
