Some of my earlier designed blades had horizontal threading through the posts, fig. 90, to allow for "screwing in" of the prosthesis without the use of cement, figs. 91, 92, 93. However discoloration of the underlying metal developed as well as cases of halatosis occurred causing me to drop this system. Final x-ray, fig. 94.

Sometimes in totally edentulous cases, figs. 95, 96, a continuous groove rather than interrupted grooves are created, fig. 97, making it a bit easier to line up the blade posts with the opposing teeth, fig. 98. After suturing, fig. 99, and healing, fig. 100, the restoration is cemented, figs. 101, 102. The post-operative x-ray, fig. 103.
