Background: in nursing homes there are 50-80% of partial or total edentulous need prostheses. Loss of these dentures is frequent, so it is important to put an identification mark. This would also serve the purpose of forensic identification. The aim of this work is to collect different solutions to prevent the loss of dentures of elderly people in residences, and propose a new one. Materials and methods: a literature review of scientific papers on the loss of dentures of the elderly in residences has been made. Results: according to the bibliography consulted, a) the marking of the prosthesis can be on its surface (engraved, painted, barcode), b) it also be included in it (identification marks, lenticular card, barcode, microchip, photographs, code of data matrix, microlabels, memory card), or c) it can be marked outside the prosthesis (boxes with the name). Conclusion: a simple method is proposed to prevent the loss of dentures. A dental floss is attached to the prosthesis that is in the mouth and on the other hand it is attached to a safety pin that is fixed on the patient's clothes.
