How long can dental implants last for patients with periodontitis?

For patients with periodontitis, dental implants can typically last more than 10 years—and in some cases 20 years or longer—if the condition is well-controlled and proper care is maintained. If any discomfort occurs, it is advisable to seek medical attention promptly and follow the doctor's instructions for treatment.

If periodontal inflammation has been successfully treated and alveolar bone loss controlled prior to implant placement, and if regular follow-up maintenance is performed after surgery, the integration between the implant and the jawbone can remain stable. Under these conditions, the lifespan of the implant can be close to that seen in individuals without periodontal disease. However, if periodontitis is not fully controlled before surgery or if inflammation recurs afterward, accelerated alveolar bone loss may occur, leading to implant loosening and a shortened functional lifespan.

The longevity of dental implants is also closely related to daily maintenance. Patients who maintain good oral hygiene, avoid chewing excessively hard foods on the implant, and undergo regular periodontal examinations and professional cleanings can reduce the risk of inflammation and extend the life of their implants. Conversely, inadequate care may lead to peri-implantitis, compromising the stability of the implant.

Daily care should include brushing with a soft-bristled toothbrush, using dental floss and interdental cleaners to clean around the implant and adjacent teeth, and rinsing with a water flosser to remove debris from hard-to-reach areas. Rinsing after meals helps prevent food accumulation. Additionally, patients should schedule a periodontal evaluation and implant maintenance appointment every six months to one year.
