Contraindications to implantology

Certain conditions that a patient may have are contraindications to implant surgery, as the complications that can occur can be serious and even life-threatening. Contraindications can be classified into three categories:

  • absolute contraindications: dental implants cannot be considered;
  • relative contraindications: dental implants can be considered only after a solution is applied to a condition;
  • local contraindications: dental implants can be considered with additional precautions for problems in the mouth or jaws.

The following blocks present a non-exhaustive list of the most common absolute, relative and local contraindications, the risks of placing dental implants under these conditions, as well as possible solutions. It should be noted that only a specialist can accurately assess a patient’s eligibility for implantology, based on the information gathered during the initial consultation with the patient and the known contraindications.
