When the ridge is high and wide, fig. 164, the making of the grooves becomes less difficult, fig. 165. The blades can be tapped into position with a little more authority, figs. 166, 167, and the tissues are then sutured, fig. 168. Within several weeks healing is almost completed, fig. 169, and the bridgework is cemented with a hard cement, figs. 170, 171. Final x-ray, fig. 172. Sometimes there exists a labial overhang of bone, fig. 173, which should be removed to lessen the chances of perforation of the underlying labial plate of bone when the groove is made and the implants are set into them, fig. 174. The healed tissues, fig. 175, readily accept the full arch fixed restoration, figs. 176, 177, 178, 179. Final x-ray, fig. 180.
