Contraindications to Implantology

There are certain medical contraindications to implant therapy, as complications that may arise can be serious or even fatal in certain conditions. Contraindications may be classified into three categories:

  • Absolute contraindications: dental implants cannot be considered;
  • Relative contraindications: dental implants may be considered only after a specific problem has been solved;
  • Local contraindications: dental implants may be considered by taking extra precautions regarding problems involving the mouth or jaws.

Here is a non-exhaustive list of the most frequent local, relative and absolute contraindications.  It includes information about the risks of dental implants under these conditions, as well as possible solutions. It is worth noting that only a specialist can accurately assess the eligibility of a patient for dental implants, according to the information collected during the initial consultation with the patient (including known contraindications).

  • Undergo an orthodontic treatment before the installation of the implant.

Are orthodontic treatments a contraindication to implants?

Are orthodontic treatments a contraindication to implants?

An orthodontic treatment is not a contraindication to dental implants. However, if a patient with a malocclusion is considering the insertion of dental implants, it is important to consult an orthodontist beforehand. This specialist will determine the best time to proceed with the implantology treatment in order not to impair the orthodontic treatment, as a dental implant cannot be moved with braces.

In addition, an orthodontic treatment may, in some cases, prevent the need for dental implants. The patient will therefore benefit from consulting an orthodontist in the first place!
