An extremely resorbed clinical picture, fig. 212, reveals also an extremely atrophied mandible, fig. 213. An impression and bite of heavy silicone material was used, fig. 214, which began the processing of the subperiosteal implant, fig. 215, which fitted with extreme accuracy, fig. 216. The temporary denture was carefully checked, fig. 217. The tissues healed remarkably well, fig. 218, and the dentures were completed, fig. 219. Fig. 220 shows the x-ray.
