[Single support of atrophic edentulous mandible with endosseous implants. Modified method of implantation with Ledermann titanium plasma-coated screw implants (TPS)]

In contrast to the usual technique of Ledermann to implant four TPS-implants in edentulous mandibles a modified method with only two implants is described. The advantages of taking only two implants are the easier implantation technique, the lower costs, and especially a better dynamic of the full denture. In connection with a round bar most of the pressure produced by the masticatory muscles is taken by the mucosae and almost no eccentric forces effect on the implants. This technique should only be applied combined with a denture in the edentulous upper jaw. Strictly regarding the range of indications our rate of failure with two implants is not higher than with the usual method described by Ledermann.
