Dental implants provide greater structural support and last longer than either dental bridges or dentures. They serve as the artificial root to which new teeth are bonded.
Types of Dental Implants

Root implant :-In implant dentistry, this is the most popular form of dental implant. This type of dental implant is very effective and mirrors the size and shape of a patient's natural tooth. Once the dentist applies the local anesthesia, he or she makes an incision in the gum in order to gain access to the jawbone. The bone is then prepared, and the dental implant is inserted into the jawbone with care and precision. Finally, the dentist stitches the gums and, if necessary, prescribes an appropriate medication.

During the Osseo integration step, which lasts anywhere from three to eight months, the jawbone firmly attaches itself to the dental implant. Once Osseo integration is complete the dental implant is fitted with the new tooth.

Plate form implant :-Another form of implant dentistry is the Plate form implant. This dental implant is ideal in situations where the jawbone is not wide enough to properly support a root implant. The plate form dental implant is long and thin, unlike the root implant, and anchors into thin jawbones. The insertion process is the same as for a root implant, but in certain cases, plate dental implants are immediately fitted with the restoration without waiting for the Osseo integration period.

Subperiosteal implant :- This dental implant method is utilized when the jawbone has receded to the point where it no longer supports a permanent implant. These implants are placed on top of the bone and embedded in the gum's, but not in the jawbone as with the other types of dental implants. The dentist applies a local anesthesia, and makes a mold of the mouth and jawbone. From this impression, a dental lab constructs implants to custom fit the patient's jaw. The dentist exposes the jawbone and inserts the dental implant on top of it. Over the next month the gum's grow up and around the implant. This same type of implant can sometimes be performed in a single procedure with the use of an initial CAT scan of the gum line and jawbone.

Preservation Required
Although patients should always practice proper dental hygiene, this is especially true once a dental implant has been put into place. When teeth and gum's are not properly cleaned, bacteria can attack sensitive areas, causing the gum's to swell and the jawbone to gradually recede.
