It has become necessary to consider how to deal with implant patients when they reach a very old age or require nursing care. In the case of patients who are no longer able to visit the dentist for maintenance or who require nursing care due to aging or disease, it will be difficult to manage the implant prosthetic device and respond to changes in the oral cavity. In addition, it is difficult to cope with peri-implantitis, implant mobility, fracture of the superstructure or abutment due to age-related changes, and loosening of screws due to deterioration of oral hygiene.

In future implant treatment, prosthetic devices that can adapt to changes in the patient's oral cavity and maintain long-term stability during the patient's life stages will be required.
