Do implants always work? No! Implants have a very high success rate, but their success is predicated on a host of conditions such as; quality of bone, location of the implant, biting forces on the implant, the immune system of the body, amount of surrounding bone, home care of the patient, etc. Implants may require additional treatment once placed in the mouth due to compromising situations and such treatment is not covered under this warranty. However, if implants placed in our office fail with a 5 year period of time we will replace the implant or the placement fee will be credited toward alternative therapy in our office.
