When two cuspids are the only teeth remaining, a full arch restoration is usually obtainable providing the cuspids are well supported by bone, fig. 12. The grooves were made in knife edge ridges on both sides of the arch, figs. 13, 14; the blades were made to fit passively into the grooves, fig. 15, and carefully tapped to their proper depth, fig. 16. The tissues were closed with 000 silk sutures, fig. 17. Within ten days uneventful healing occurred, fig. 18. The teeth were then prepared and the bridge was completed, fig. 19, and cemented, fig. 20. Fig. 21 shows final x-ray.
