Dental implants are used to replace missing teeth, or badly damaged teeth that have no chance of survival. Implants can replace one tooth, or a whole set. Metal fixtures, acting as artificial roots, are screwed into the jawbone to act as anchors for the new false teeth, which are known as crowns.
In time the implants fuse with the jawbone in a process known as osseointegration, creating a strong permanent bond. The attached crowns closely simulate the function and appearance of real teeth, making implants an attractive and effective alternative to bridges and dentures.
Instead of attaching artificial teeth, implants may also be fitted with clips to securely hold dentures.
