Dental implants are generally not age-restricted and can be placed in the elderly. The success or failure of dental implants depends on the quality and quantity of the alveolar bone. The bone quality of the elderly is relatively lax, and the alveolar bone resorption is obvious, but this does not mean that the elderly cannot have dental implants. Under the premise of controlling diabetes, hypertension, heart disease, cerebrovascular disease and other chronic diseases common to the elderly, a considerable number of elderly patients with missing teeth are suitable for dental implant restoration. For patients with poor alveolar bone conditions, doctors use minimally invasive rapid, bone grafting techniques, bone extrusion and other techniques to make the alveolar bone fully capable of meeting the requirements for dental implants, and there are some elderly people whose alveolar bone is in very good condition and thus more suitable for implant surgery. We have successfully performed dental implant surgery for 85-year-old patients, and many elderly patients are currently undergoing implant surgery in our hospital, and we have conducted corresponding clinical and basic research on implants for the elderly.
