Dental implants are offered to sufferers as perfect or near perfect alternatives to their lost teeth. Rarely are they advised of the risks and counseled on the failing rates and the processes can have serious effects and is not perfect. Implants can and do fail, sufferers want to be thoroughly informed about the risks and realize that dental implants can fail. With suitable arranging, implant placement is very predictable, secure and makes a useful and aesthetic final result for patients. Dental Implants have appeared long since their beginning in the 1950’s and dental implant technology is modifying at an amazing rate.
So what creates dental implant failure? There are a variety of things that cause an improved risk in a dental implants procedure, unfortunately a few of the risks are not avoidable and that is why dental implants are about 90-95% effective based on numerous studies. As with long bone injuries, even with the best approximation of the fracture and excellent immobility, some fractures basically aren’t recovered when the cast is removed. Either a non-union happens (meaning no healing ever actually started) or a fibrous union happens where instead of the bone between the two ends of the fracture you have scar cells. Based on the kind of fracture and where it is, non-unions and fibrous unions happen about 5% of the time.
The similar concepts of healing from a fracture are congruent with the treatment of an implant. You require good approximation of the bone to the implant surface area and a time of immobility to have an effective Osseointegration of the implant. Osseointegration means the bone accepted the implant and contains itself within the implant. As you can see, the failed amount of implants is similar to the rate of fractures not healing effectively. You can get failure of the bone to Osseointegrate (comparable to non-unions) and instead of bone around an implant you get a fibrous encapsulation (just like fibrous union in bone fractures).
However certain situations that improve the risk of implant failure are: badly handled diabetes, some bone metabolic and congenital conditions, specific medicines like glucocorticoids (prednisone), immunosuppressants and bisphosphonate medicines (Zometa, Fosamax, Actonel, Boniva, etc.) Furthermore, smoking and weak hygienic behavior can cause an increased risk of implant failure. People with these conditions and/or on these medications should bring those to the attention of their implant surgeon so a treatment plan can be designed to fit to their requirements and their medical circumstances.
There are other aspects that can cause an increase in dental implant failure. Implants can fail early on in the healing stage or late. Early failures would be identified at any moment before Osseointegration happens (healing phase) or during the time the crown is affixed to the implant. Late failure is identified at any moment after the implant with the tooth is under function. Before having the implant positioned, the surgeon should describe almost everything to you and if you think that you did not obtain sufficient information then wait until you are ready and totally informed, find good details to help teach you.
