This case lasted about seven years before resorption of the bone around the already weakened anterior teeth and beneath the implants had dictated their removals. Figs. 25, 26 reveals a close up of the implant and master stone model. The implants are inserted, fig. 27, and the tissues sutured together, fig. 28. A vent-plant screw was screwed into the bone between the subperiosteal implant and remaining incisor tooth to give more support, fig. 29, 30. An impression was taken, fig. 31, for a gold framework, fig. 32, onto which acrylic was processed, fig. 33. The case as seen in the mouth, fig. 34, and the post-operative x-ray, fig. 35.
