the periodontally involved left cuspid, fig. 38. Another full arch fixed restoration was inserted and cemented, figs. 39, 40, 41A, 41B.

Sometimes, but not too often, in a totally edentulous mandible, fig. 42, the insertion of two anterior blades, figs. 43, 44, 45, can be enough to stabilize a denture, especially when no bone exists posteriorly. Splinting the blades to each other with a Dolder bar with resilient Gerber attachments, figs. 46, 47, to take the pressure off of the implants, can sometimes serve the purpose, figs. 48, 49, 50, 51. A post-operative x-ray of the case, fig. 52.
