Implant Survival.

Implants have been reported to be still present after 30 years but several factors are associated reductions in implant survival. There appear to be two types of implant failure:

  1. Early Loss (within the first 12 months ~1-3%); and
  2. Late implant loss (usually after the 5th year and up to 20%).
Early Loss:

The early implant loss seems to be associated with implant exposure into the oral cavity and a reduction in the initial post-surgery stability. Higher plaque scores and gingival inflammation are found to correlate with this early loss and the initial bone loss after implant placement. This suggests that a combination of bacterial colonization into implant sites and the lack of stability of the implant may allow bacteria to prevent integration of the bone around the implant. Several steps can be taken to reduce this initial implant loss and we consider these approaches to be the normal measures we apply when we place the implants to prevent this early loss.

Late Loss:

Most implants that are lost occur via this mechanism. Factors that relate to this late loss are:
