A three quarter fixed prosthesis was fabricated for this patient with a cantilevered pontic extending distally from the right cuspid crown. The bridge was cemented permanently while the sockets from two extracted teeth on the right side had three months to heal. A double posted blade was then tapped into a groove made in the healed bone, fig. 60, and a four unit fixed pros-thesis was cemented into position using the cantilevered pontic as anterior support, figs. 61, 62. Doing it in this manner allows the bladevent to resist bucco-lingual movements far greater than if an isolated unilateral fixed bridge were to be made. Fig. 63, shows the final x-ray.

Occasionally, when excellent bone support exists both in the edentulous area and around a remaining cuspid tooth, even though the span is greater than usual, a blade can be used as posterior support, fig. 64, with just the cuspid for support anteriorly. With bladevents in the mandible the type of restoration makes no difference as to the overall success. Here is seen a porcelainfused-to-metal fixed bridge, fig. 65, but gold veneer crowns or acrylic over gold crowns can also be used successfully. A final panoramic x-ray shows this case, fig. 66. Another case shows a single posted blade with two anterior abutments, fig. 67. However, a four unit acrylic veneer bridge was processed with gold occlusals, figs. 68, 69. Fig. 70 shows the final x-ray.
