When no implant can be inserted
Although the implant can be considered the almost ideal solution for lost teeth, there are certain situations where an implant is out of the question. People who suffer from a change in the bone structure, as is the case with osteoporosis, for example, or who have to take bisphosponates, are usually unsuitable for implants, as great difficulties must be expected during the growing together with the jawbone. Patients after chemotherapy also have to wait for some time because chemotherapy weakens the immune system so much and the implant cannot be securely anchored in the jawbone as a foreign body.
Implants should also not be placed if oral hygiene is inadequate, as the risk of periimplantitis, a disease similar to periodontosis, is increased. It causes the bone to retract and as a result the implants fall out. An already existing, untreated periodontitis is also an exclusion criterion.
Untreated periodontitis causes the jawbone to retract over time due to the inflammation caused by plaque. The implant can then no longer be sufficiently anchored and falls out. On the other hand, treated periodontitis is not a reason to exclude an implant.
