Dental implants are given to patients as perfect or near perfect replacements with their missing teeth. Rarely could they be informed with the risks and counseled on 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 understand that dental implants can fail. With the right planning, implant placement is extremely predictable, safe and creates a functional and esthetic result for patients.Teeth implants have come an extended since their inception in the 1950's. Dental implant technology is changing at an incredibly fast rate. As each new technologies are adapted, dental implant success usually improves. Occasionally a technology comes into the marketplace that is mostly great marketing and either doesn't not improve the success or actually hinders it. Fortunately that does not happen very newsletter serviceSo what makes dental implants fail ? There are numerous of factors that lead to an increased chance of dental implant failure. Unfortunately a few of the risks usually are not avoidable and that is why dental implants are about 90-95% successful depending on various studies (the amount is actually closer to 95%). As with long bone fractures, despite the best approximation from the fracture and great immobility, some fractures simply aren't healed if the cast is slowly removed. Either a non-union occurs (meaning no healing ever really started) or even a fibrous union occurs (where rather than bone forwards and backwards sides of the fracture you've got scar tissue). Depending on the type and 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 teeth implants.The same principles of healing from a fracture are congruent with all the healing of your implant. You'll need good approximation of the bone for the implant surface along with a period of immobility to have a successful osseointegration of the implant. Osseointegration means the bone accepted the implant and incorporates itself across the implant. As you can tell, the failure rate of implants resembles the rate of fractures not healing properly. You can get failure with the bone to osseointegrate (just like non-unions) and rather than bone around an implant you have a fibrous encapsulation (similar to the fibrous union in bone fractures).However certain issues 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 likelihood of implant failure. People with these disorders and/or on these medications should bring those to the attention of their implant surgeon so a treatment plan can be tailored to suit their needs and their medical conditions.There are many 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 would be defined as at any time before osseointegration occurs (healing phase) or during the time the crown is affixed to the implant. Late failure is defined as any time following your implant using the tooth is under function.
