Implant therapy in older patients: Prosthetic considerations and biomechanical implications for frailty/aging

Periodontology 2000, EarlyView.
Abstract Background Population aging is reshaping prosthodontic care for both partially and completely edentulous individuals. In older adults, conditions such as frailty, comorbidities, polypharmacy, and cognitive decline can have a direct impact on the biological and biomechanical demands of implant therapy, thereby influencing the success of implant
