What does dental implant failure mean?
Implant “failure” can describe several different situations. The implant may not bond with the bone during healing, it may lose supporting bone over time, or a mechanical part may fracture. The crown or bridge can also fail while the implant itself remains stable.
The main categories include:
- Early integration failure: the implant does not become firmly anchored during the healing phase
- Peri-implant disease: inflammation affects the gum and, in peri-implantitis, the supporting bone
- Mechanical complications: screws, abutments, the implant body, or restorative materials loosen or fracture
- Restorative failure: a crown, bridge, denture, or full-arch prosthesis chips, wears, breaks, or no longer fits
- Positional or aesthetic complications: the implant cannot support a cleanable, functional, or acceptable restoration
These categories can overlap. A loose screw may alter the bite, a poorly fitting restoration may be difficult to clean, and inflammation can develop alongside component damage.
