There are some details in implant overdentures design that can influence their long-term survival. Biomechanics determine the way overdenture works under function, so it will be a main factor to decide the number of implants, type of attachment and teeth mounting procedures. Besides, attachment selection is very closey related to the need of splinting implants and the incidence of complications will depend mainly on the bar design. We also know that, as bone resorption takes place below an implant-mucosa supported overdenture, the load directed to the implants increases, and this area of the overdenture is so thin that it can fracture. For this reason, it is necessary to reinforce the overdenture with a Co-Cr structure. In this article, all this factors will be dealt with in detail.
