A dental implant is a metal (usually titanium) screw that is placed into the jaw bone through surgery in a dental practice. The screw acts as an anchor for an artificial tooth or a set of artificial teeth. Dental implants are an excellent option for people in good oral health who have lost a tooth or teeth. Implanted teeth look and feel like a patient's own teeth. They are very secure.
There are two types of implants - Endosteal and Subperiosteal.
Endosteal Implant Procedure (most common)
Surgery is performed to place an anchor (screw) into the jawbone. This is called osseointergration. Healing may take up to 6 months for bone to grow around the anchor and hold it in place.
A second surgery may be performed to attach a post to the anchor. This may also be done during the first surgery.
The restorative (replacement) teeth are made and fitted to the post portion of the anchor.
Subperiosteal Implant Procedure
A Subperiosteal implant rests on the jawbone rather than being placed into the jawbone. The jawbone is surgically exposed and an implant is made of the jawbone. Subperiosteal implants are generally used for patients who have minimal bone height and are unable to wear traditional dentures.
From the mold, a metal frame is fabricated.
During the second surgery, the jaw is reopened and the metal frame fitted onto the jawbone. Posts protrude through the gum tissue. As the gum tissue heals, the implant is attached to the jaw.
The protruding posts support a denture.
