Can the success of an implant therapy be guaranteed?
Dental implants have been in use for over fifty years. They have been proved to last for a very long time. A great number of clinical studies have attested to this fact. Your implants could give you good and long lasting service (over thirty years). When have bonded with the bone they cannot be dislodged.
Once successfully placed and integrated they have been documented to have a survival rate of 99%. That means that only one in hundred cases face the prospect of implant rejection. Usually this happens because of poor patient selection or improper implant placement. The skill and judgment of an implantologist cannot be over-estimated.
Poor outcome can be expected when patient has deficient or low quality bone. The contributing factors are uncontrolled diabetes or smoking habits.
While no absolute dental implant guarantees can be given, dentists will often offer to remove and replace an implant that has not bonded with the underlying bone with another one after a suitable interval of healing.
