number of factors influence whether implants can be placed, and whether
they will be successful in the long term. These factors include:
The health of the jawbone and its capacity to heal well, the bone
density and the general health of the mouth.
The number of implants and the type of prosthesis.
Whether the implants are wanted in the upper jaw or lower jaw.
general health of the patient.
Implant failure - There are virtually no recorded instances of allergy
to titanium metal, so the possibility of the implant being ''rejected''
does not arise. However, occasionally the bond between the bone and
the implant, necessary for the success of the implant, does not occur.
This involves about 2 - 3% of all implants and the reason is not fully
Discovery of this failure normally occurs at the time of second stage,
and the implant will then often be immediately replaced with a larger
diameter fixture. This second fixture has then the same high probability
of successful integration as the original. Replacement of a failed
fixture does add extra time to the treatment process.
Dental implants have a high success rate, which has been scientifically
documented over 35 years.
