What actually are the components of Dental Implants? The Dental Implant Complex comprises a series of parts that are stacked on each other and bolted or cemented together.

At the base of the complex is the dental implant fixture. This is usually a titanium or titanium alloy screw that is inserted into the jaw bone with a minor surgery. Implant fixtures made of other materials such as Zirconia are also available.

After a period of healing, the jaw bone fuses with the implant fixture, stablizing it and anchoring it to the bone. This usually takes 2-3 months.

At this point, an impression is made to register the position, depth and angulation of the dental implant fixture. This can be done with a conventional silicone impression or digitally via an intraoral scan. An analog or digital model is then fabricated.

Depending on the type of restoration that is being planned, the parts for the dental implants will differ. For single crowns and bridges, the restorations can be cemented or screw retained. For cemented restorations, a titanium or ziconia post is connected to the impant fixture. Based on the design of the abutment, these can be fixed with a retaining screw, or directly screwed into the dental implant fixture.

The crown or bridge is then fabricated, similar to what is done with tooth-bourne restorations, and the restoration is cemented onto the implant abutments.

Screw-retained implant restorations do not use an abutment. Instead the restoration is bolted directly to the dental implant fixture with a retaining screw. The restoration can be a single piece, with porcelain baked directly onto a metal framework or a monolithic zirconia crown or bridge. Alternatively, it can be a zirconia restoration that is cemented onto a titanium base.

Screw-retained restorations are technically more difficult to make and deliver, but they use less components, resulting in a lower complication rate. They are also easier to maintain.

In the case of implant-retained dentures, specialized parts, such as locator attachments, are connected to the implant fixtures. The complementary parts are embedded into the denture. These attachements allow the dentures to clip on to the dental implants, improving retention and stability.
