In this situation, the patient had only two remaining teeth, fig. 25, of which one was later removed. She also had a severe overbite and overjet which I thought could be greatly reduced by designing the anterior posts of a universal subperiosteal implant to rest extremely in a labial position. The tissues were incised and retracted as well as the left loose cuspid extracted and an impression for the universal type subperiosteal implant was taken, figs. 26, 27. Fig. 28 shows the anterior posts on the labial edge of the ridge, which when inserted over the bone, figs. 29, 30, made it impossible to suture the tissues closed. By removing both anterior posts and their secondary supporting struts, still leaving the entire implant in one piece, thus not reducing its over-all retention, fig. 31, a double-posted bladevent was inserted in the anterior quadrant, figs. 32, 33, and the tissues were sutured together, fig. 34. Healing was excellent, fig. 35. The x-ray shows
