expectations, fig. 66, and the implant denture was fitted to place, fig. 67. Although asymmetry of both sides of the jaw existed, the patient wore this appliance successfully for more than six years before he had a heart attack and died. The post-operative x-ray, fig. 68.

Many problems occurred with the retention of the dentures after several years with the early designed extremely short posts. Internal clasps broke reducing the overall retention of the implant denture even though the implants were successfully functioning.

Before I started designing the posts to be much larger, improvising the existing short posted subperiosteal implants had to be done. Dolder or Andrew type bars attached to gold copings were used with internal clips, figs. 69, 70, 71, 72. Sometimes Hardy posterior teeth are used in those cases where patients require a sharper grinding apparatus, figs. 73, 74, 75, 76.
