Most common causes of dental implant failure

Fortunately, over 95% of dental implants are successful.

But what causes the rare failures that can occur?

Implant related gum disease (peri-implantitis)

The soft and hard tissues surrounding an implant are susceptible to a form of inflammation known as peri-implantitis. This can lead to bone loss and infection which could result in the loss of an implant.

Excessive stress on the implant

If a patient has the habit of grinding or clenching their teeth when they are stressed, this can place high levels of pressure on their teeth that an implant may not be able to withstand.

Poor overall health

People who are taking certain medications or who are in poor health may not be ideal candidates for dental implants. If your immune system has been compromised you may be less likely to heal well following an implant procedure.

Smoking or other tobacco use

Smokers suffer from the highest rates of implant failure. Nicotine causes blood vessels to constrict which limits the supply of oxygen and nutrients available for healing. Smoking can also cause inflammation around an implant which may result in peri-implantitis.

Insufficient bone structure or failed bone grafts

Thick, dense bone is the best foundation for a strong implant. In areas where there is insufficient bone or the bone has degenerated due to tooth loss, Oral surgeons can perform bone grafts to increase the volume of bone.

Poor oral hygiene habits

Good oral hygiene is important for the ongoing success of an implant. While you no longer have to worry about tooth decay, maintaining healthy gums and surrounding teeth will ensure your initially successful implant does not fail due to a later development of gum disease.
