Demographic developments indicate an increasing proportion of elderly persons in the population as well as longer life expectancies. Furthermore, the prevalence of edentulism is decreasing, and natural teeth are being retained until later in life. Geriatric patients are more frequently fragile with multiple co-morbidities, including frequent medication-related side effects such as xerostomia. Cognitive impairment also increases with age and presents a considerable challenge to oral hygiene and dental treatment. Edentulous patients present a particular challenge, as muscle skill and the ability to adapt to a new denture diminish with age. Duplication techniques reduce the adaptation of replacement dentures, and implants are increasingly used to stabilise lower complete dentures, significantly improving chewing efficiency and preventing peri-implant bone loss. Implant overdentures may reverse some of the functional, psychological and psychosocial effects of tooth loss and thus increase the oral health-related quality of life until late in life. Evidence from RCTs exists on the 10-year survival of implants and implant overdentures, but few studies have investigated the problems and survival rates when the patient loses autonomy. The standard of care in geriatric patients has to be adapted to the patient's motivation, functional and cognitive impairment, and medical condition as well as his/her socio-economic context.
