A method is proposed using a silicone tube to allow the restoration of incongruous prostheses due to the retention of removable prostheses anchored to implants by ball-attachment, also in medical facilities Health Care Residence (RSA) where the equipment characteristic of dental clinics is lacking. One hundred and thirty-seven patients belonging to the Health Care Residence of the Monza and Brianza area were analyzed. Of these, 13 required retention replacement for ball attachment of total lower prostheses to implant anchorage. The new retention procedure was carried out with the patients bedridden according to the methodology of the present work. All 13 patients were perfectly rehabilitated in the Health Care Residence offices without discomfort and pain. The method presented is easily repeatable, risk-free and can also be carried out in structures not dedicated to dentistry, saving economic resources and inconveniences for patients who are not cooperative.
