Dental Newsletter Service Dental implants are given to patients as perfect or near perfect replacements to their missing teeth. Rarely is it 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 need to be thoroughly accustomed to the risks and realize that dental implants can fail. With the right planning, implant placement is extremely predictable, safe and helps to create a functional and esthetic result for patients. Teeth implants have come a lengthy since their inception in the 1950's. Dental implant technologies are changing with an incredibly fast rate. As each new technologies are adapted, dental implant success usually improves. Occasionally a technology has the marketplace that's mostly great marketing and only doesn't not improve the success or actually hinders it. Fortunately that does not happen very often. dental practice newsletter So what makes teeth implants fail ? There are numerous of factors that cause an increased chance of dental implant failure. Unfortunately a number of the risks are not avoidable and that's why teeth implants are about 90-95% successful depending on various studies (the number is actually nearer to 95%). As with long bone fractures, despite having the best approximation from the fracture and great immobility, some fractures simply aren't healed when the cast is taken away. Either a nonunion occurs (meaning no healing ever really started) or a fibrous union occurs (where rather than bone forwards and backwards sides with the fracture you have scar tissue). Based on the type where the fracture is and the patient, non-unions and fibrous unions occur about 5% of that time period. That is similar to the failure rate of dental implants. The same principles of healing from your fracture are congruent with the healing of the implant. You need good approximation from the bone for the implant surface along with a period of immobility to have a successful osseointegration with the implant. Osseointegration means the bone accepted the implant and incorporates itself across the implant. As you can see, the failure rate of implants is similar to the rate of fractures not healing properly. You will get failure from the bone to osseointegrate (just like non-unions) and as opposed to bone around an implant you have a fibrous encapsulation (just like the fibrous union in bone fractures). However certain problems that increase the likelihood 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 lead to an increased chance of implant failure. People with these disorders and/or on these medications should bring the theifs to the attention of their implant surgeon so a therapy plan may be tailored to match their needs in addition to their medical conditions. There are more factors that can lead to a rise in dental implant failure. Implants can fail in the beginning in the healing phase or late. Early failures could be defined as at any time before osseointegration occurs (healing phase) or at that time the crown is affixed towards the implant. Late failure is defined as any time following the implant with the tooth is under function.
