Dental implants provide stable support for replacement teeth and other prostheses. This lesson introduces how implants connect with bone, the main ways they are used, and the materials commonly used to make them.
A dental implant, also called an endosseous implant or fixture, is a prosthetic device placed in the bone of the jaw or skull. It provides an anchor for a crown, bridge, denture, facial prosthesis, or orthodontic appliance. The implant fixture usually resembles a screw and acts much like an artificial tooth root.

What is a dental implant fixture?
It is the part placed in jaw or skull bone that serves as an anchor for a dental or other prosthesis.
Define osseointegration.
Osseointegration is the close biological connection that forms when bone grows into contact with a suitable implant surface.
What is the function of an abutment?
An abutment connects the implant fixture to the crown, bridge, denture, or other prosthesis.
Name two materials used for dental implants.
Titanium, including titanium alloys, is most common; zirconia-based ceramics are another option.
What are two non-tooth-replacement uses of implants?
Implants can provide orthodontic anchorage and can retain facial prostheses or obturators.
Quiz questions
During implant site preparation, why is irrigation used while drilling?Answer: To limit heat and protect bone cells during drilling.
What characterizes a one-stage implant surgery approach?Answer: A healing abutment remains exposed through the gingiva during healing.
When is delayed immediate implant placement commonly performed after extraction?Answer: After a short healing interval, commonly two weeks to three months.
How does secondary stability develop around a dental implant?Answer: Biological support develops as bone grows around the implant.
What does implant survival generally indicate?Answer: The implant remains in place.
