Dental Practice Newsletters

Dental implants are made available to patients as perfect or near perfect replacements for their missing teeth. Rarely could they be informed from the risks and counseled about the failure rates. The procedures may have serious consequences and isn't perfect. Implants can and do fail. Patients have to be thoroughly informed about the risks and realize that dental implants can fail. With correct planning, implant placement is extremely predictable, safe and fosters a functional and esthetic result for patients.Tooth implants have come an extended since their inception in the 1950's. Dental implant technologies are changing at an incredibly fast rate. As each new technologies are adapted, dental implant success usually improves. Occasionally a technology makes the marketplace which is mostly great marketing and only doesn't not improve the success or actually hinders it. Fortunately that does not happen often.dental practice newsletterSo what makes teeth implants fail ? There are a number of factors that lead to an increased risk of dental implant failure. Unfortunately some of the risks usually are not avoidable and that's why teeth implants are about 90-95% successful according to various studies (the number is actually nearer to 95%). As with long bone fractures, even with the best approximation with the fracture and great immobility, some fractures simply aren't healed if the cast is taken away. Either a non-union occurs (meaning no healing ever really started) or perhaps a fibrous union occurs (where instead of bone between the two sides from the fracture you've scar tissue). With respect to the type and where the fracture is as well as the patient, non-unions and fibrous unions occur about 5% of the time. That is similar to the failure rate of tooth implants.The same principles of healing from the fracture are congruent with all the healing of your implant. You will need good approximation from the bone towards the implant surface along with a period of immobility to get a successful osseointegration from the implant. Osseointegration means the bone accepted the implant and incorporates itself round the implant. As you have seen, the failure rate of implants is comparable to the rate of fractures not healing properly. You may get failure from the bone to osseointegrate (just like non-unions) and instead of bone around an implant you have a fibrous encapsulation (just like the fibrous union in bone fractures).However certain issues that increase the chance of implant failure are poorly controlled diabetes, some bone metabolic and congenital disorders, certain medications like glucocorticoids (prednisone), immunosupressants and bisphosphonate medications (Zometa, Fosamax, Actonel, Boniva, etc.) Additionally, smoking and poor hygienic habits can result in an increased chance of implant failure. People who have these disorders and/or on these medications should bring the crooks to the attention of these implant surgeon so a therapy plan can be tailored to suit their needs and their medical conditions.There are other factors that can lead to a boost in dental implant failure. Implants can fail in the beginning in the healing phase or late. Early failures would be defined as at any time before osseointegration occurs (healing phase) or at that time the crown is affixed for the implant. Late failure is understood to be any time after the implant with the tooth is under function.
