General Considerations:
- An implant is a man-made replacement for a tooth root.
- Because of their very unique design, they become securely attached to the jawbone through a process called osseointegration.
- After a waiting period that allows the bone to heal around the implant, final restorations are screwed or cemented onto the implant or implant component.
- The final restoration is made utilizing procedures that are very similar to traditional crown and bridge dentistry.
- With Michigan Dental Implants, it is possible to replace a single tooth, multiple teeth, or an entire arch of teeth.
- For patients who are faced with losing all of their teeth, implant dentistry provides a tooth-replacement option that is much more stable and permanent than removable dentures or partials.
Implant Composition
- Implants are constructed from titanium.
- Titanium is a lightweight, soft, noncorroding metal.
- The surface of the titanium forms a natural ceramic coating when exposed to oxygen which enables bones cells to attach to it.
- Since bone cells react better to titanium surfaces that are rough, most implants are put through a roughening process by the manufacturer.
- To enhance bone healing, implants are sometimes coated with hydroxyapatite.
- Implants are often threaded. In order to enhance implant placement and stability, thread shape and pitch are carefully calculated to help transfer biting force to the surrounding bone.
Osseointegration
- Osseointegration describes the attachment of bone to the surface of an implant.
- Observation of an osseointegrated implant under a microscope reveals that bone attaches to the implant surface, but not in a continuous fashion. There are areas of direct contact separated by marrow spaces; therefore, only 40%-50% of the implant is in contact with bone.
- Surface treatment, such as a hydroxyapatite coating, work to increase the bone/implant contact.
- Under clinical observation, an osseointegrated implant will feel solid with no present mobility.
- When an implant fails to osseointegrate, slight mobility is noted. In such cases the bone surface is separated from the implant surface by a thin fibrous membrane which may be visible with careful x-ray analysis.
- A waiting period is required for successful osseointegration to occur because a complex series of events must occur.
