Unbeknownst to many, there are multiple reasons for implant failure. Although dental implants have a high success rate of 98%, they may fail occasionally due to existing factors. So what causes dental implant failure and why?
Early and Late Implant Rejection
There are two stages of the dental implant process when implant rejection may occur. These are known as early and late implant rejections.
Early rejection can occur if the patient receiving the implant has an allergic reaction to the material being used. If the jawbone rejects the metal that was inserted as the foundation, it will halt the process of osseointegration and result in a failed implant.
In contrast, late implant rejection may occur once the dental implant has been successfully placed. Some factors that may cause implant failure include:
- Misaligned implants
- Post-op trauma
- Poor dental hygiene
It’s important to note that dental hygiene as well as following the dentist’s instructions are extremely important for a positive outcome. Although dental implants are not susceptible to decay, they still require proper care. Failure to maintain good hygiene practices could result in a failed implant.
A failed osseointegration is much like early implant rejection as they both occur in the beginning stages of implant placement. Osseointegration is known as the time period in which the implant and the bone bond together, establishing a strong foundation for the prosthetic tooth. Without proper osseointegration, which is the most important part of the dental implant process, treatment may no longer be possible.
A major cause of implant failure is known as peri-implantitis, which is an infection that affects the gums and forms due to bad hygiene habits. Peri-implantitis is a type of gum disease that may cause the dental implants to fail as a result of the bacteria that forms around the implants.
Peri-implantitis may occur either during or after the dental implant procedure and may lead to bone loss if not treated in time. Although this infection is treatable, in more serious cases, peri-implantitis may cause the implant to fail – leading to implant replacement.
