What are the chances of rejection of implants?
Implants that fail do so because the bone has not integrated sufficiently with the implant surface. Hence, implants are not “rejected” like an organ transplant, they simply fail to bond with the bone. This may occur if the bone is very soft at the time the implant is placed, or if the implant is initially unstable. Other reasons include inadvertent loading of the implant via a removable denture or by the action of chewing hard food over the implant site at the early stages of healing. Infection may also cause an implant to be lost. Most modern implant systems report success rates of 85-95% over a 5 to 15 years period.
