Can dental implants happen twice? Or, more accurately, will dental implants have to be repeated

A dental implant is a surgical component, a replacement root for teeth, usually made of titanium, which connects the bone of the skull or jaw, to the prosthesis that the patient may require. They are in the form of a screw with either a rough or smooth surface. Though titanium is most common, ceramic implants are also available.

While dental implants, in general, have very high success rates, there are cases where they may have to be replaced. Failures also happen usually in the first year after implant.

Following are some common possibilities:
  1. Loosened Dental Crown: Crown is a cap or cover put over a tooth that is damaged or weakened. This is not serious, but the crown may have to be tightened or replaced.
  2. Bone Loss: Poor bone quality or quantity could lead to failure of osseointegration, the direct interface between the implant and bone, further leading to implant failure.
  3. Overheating, contamination, and trauma during surgery is another cause.
  4. Bacterial infection: these affect the implants just as much as the normal teeth. So, when any other cause pushes the implant into the failure path, these bacteria worsen the situation by causing infection in the area.
  5. Failure of Angiogenesis: the formation of new blood vessels is called angiogenesis. As the implant and its surface are non-organic, the supply of blood to these areas is problematic. Hence, when insufficient new blood vessels form, the likelihood of implant failure increases.
  6. When an implant causes clinical symptoms like severe and recurring pain, facial mobility, it may be considered defective and may have to be replaced or reimplanted.

Here, it must be noted that, relative to initial implants, replacement implants have a smaller success rate. Above all that, the patient may have to go through additional hard and soft tissue graft; teeth crowns may need a replacement; longer time to heal and last but not the least, more financial costs.
