In the field of dentistry, dental implants are used to resemble the natural tooth root. Typically these structures are made from titanium and work by supporting tooth restorations. Examples of prostheses used with implants: bridges, dentures and crowns.
In general, implants are constructed with pure titanium. They include screws that are designed to mimic the natural root of a tooth. A rough or smooth surface can be obtained by techniques such as etching, plasma spraying, sandblasting, and anodizing.
These structures must be placed using surgery. Prior to performing the surgery, a dentist may advise that other tests and procedures be performed. Radiographs may be done pre-surgery to assess the dimensions, shapes and structures of a mouth. This step is important to the overall process because it assures that the implants are the correct sized and properly oriented. CT scans may also be required before the surgery. Stents may be set up for surgeons to use as a guide during implant placement.
During the actual surgery, the bone will be prepped using hand osteotomes or precision drills, both of which have speed-regulation functions to prevent pressure necrosis. It is integral that osseointegration, the bone growing to the top of the implant, occurs before any type of restoration is placed. This duration of this process depends upon the overall quality and quantity of bone.
It is common for most dentists to wait up to six months for the mouth to fully heal. This healing time will vary considerable. However, if a restoration is installed too soon after the initial surgery, the implant can fail. In some cases an implant can take up to a year to fully heal. The estimated success rate for this procedure is at 95 percent. With that said, quality and quantity of bone, oral hygiene, surgeon skill, and post-surgery maintenance all impact outcome. Most failures are the result of osseointegration not occurring.
The jawbone plays an important role in the outcome of this procedure. It must have enough strength and mass to support the implant. If not, a technique called the graft procedure may help. As is true of any surgery, complications may arise. Infection of the area can occur, and if the body identifies the implant as foreign, it will reject it. Other potential complications: periodontal disease, incision point opening, inflammation and fixtures falling out.
Dental implants are used in the field of dentistry. They are designed to resemble the natural root of a tooth and support prostheses such as crowns, bridges and dentures. Because they are installed in a surgical procedure, complications and implant failure is not uncommon.
