Which statement about artificial dental implants and infection risk is accurate?

• A. Implants have no effect on infection risk
• B. Implants prevent bacterial colonization
• C. Implants can be sites where bacteria attach and cause implant failure
• D. Implants always cause infection

Answer: (C)

Bacteria can attach to the surface of dental implants and form biofilms, which can drive infection around the implant. The patch of bacteria trapped on the implant surface triggers inflammation in the surrounding tissues (peri-implant mucositis) and can progress to peri-implantitis, where bone around the implant is lost and the implant may become loose or fail. This is why implants are not immune to infection; the surface and surrounding environment can harbor microorganisms just like natural teeth, especially if hygiene is poor or risk factors exist. Therefore, this statement is the best choice because it accurately captures that implants can be sites where bacteria attach and lead to implant failure. It’s not that implants inherently create infections in every case, nor that they completely prevent bacterial colonization, nor that they always cause infection; those are less accurate frames of reference. Proper oral hygiene, regular maintenance, and risk-factor management help reduce the likelihood of these infectious complications.
