Dental implants can hijack your immune system, scientists discover
Scientists at Rutgers have identified that titanium particles from corroding dental implants trigger an immune response that traps cells in a state of chronic inflammation. This mechanism explains why traditional antibiotics are often ineffective at treating peri-implantitis.
Why it matters
This discovery provides a specific drug target for a common, costly complication that affects up to 20% of dental implant patients.
For tens of millions of people, dental implants have provided a way to replace missing teeth with a full set of fixed, functional teeth rather than removable dentures. However, an estimated 10% to 20% of implant patients eventually develop peri-implantitis, a serious infection that damages the surrounding jawbone.
Antibiotics frequently fail to control this condition, and scientists have struggled to understand why. Now, researchers believe they have uncovered the mechanism responsible.
A new study published in PNAS Nexus by scientists at the Rutgers School of Dental Medicine reveals that bacteria can gradually corrode dental implants, releasing microscopic titanium particles into nearby tissues. These particles interfere with the immune cells responsible for fighting infection, trapping them in a state of excessive inflammation that progressively destroys jawbone.
